Klasku FAQ

Question 1

What is Klasku, and what kind of school is it for?

Accepted Answer

Klasku is an administration platform for course schools — tutoring centers, music, language, and sports schools, all the way to private lessons — bringing student records, schedules, attendance, invoices, and parent messaging into one system. Staff work in the tenant panel through a browser, while parents and teachers sign in to their own portals on a phone. The screens are built for non-technical admins, so there is no training program to schedule first; if setup stalls, our team helps over WhatsApp. One school account switches on four surfaces at once: the tenant panel for staff, the Parents Portal, the Teachers Portal, and your school's page on klasku.id. They all read the same data, so the attendance a teacher marks this afternoon is readable by parents immediately and immediately changes the remaining sessions the invoicing runs on.

Question 2

What if it is not a fit — can I stop?

Accepted Answer

Yes, any time. A Klasku subscription is monthly with no contract: stopping simply means the next renewal is not billed, with no penalty. Before you go, your school's data can be exported to a spreadsheet file on the Pro plan. The 14-day trial also runs without a credit card, so using it to the last day issues no invoice at all. The school you fill in during the trial is the same school you keep once you subscribe — nothing is migrated halfway through. School data is never used as a way to hold a customer in place. A student who leaves is closed through a status change, so their attendance and payment history stays intact, and permanent deletion under data protection law is carried out by our team on request — not through a button a staff member can hit by accident.

Question 3

Will my admin staff need special training?

Accepted Answer

No. The screens follow the daily work of a course-school admin — adding students, placing them into classes, marking attendance, issuing invoices — so what you learn is the flow, not the system's vocabulary. If setup stalls, our team helps over WhatsApp. Teachers need no training session either: you invite them from the Teachers menu, they sign in with a mobile number plus a 6-digit PIN from their own phone, and all that opens there is their schedule and their classes' attendance. What replaces training in Klasku is guardrails. A payment model must be chosen when a student is placed into a class, attendance refuses a student whose pack has run out and says which student, and an invoice that could never be settled is turned down at the input screen. A new admin can still misclick, but it is hard to create data nobody can explain.

Question 4

My school has only a few dozen students — is Klasku overkill?

Accepted Answer

There is no minimum student count. The smallest plan is built for a single-branch school, and the fewer students you have the faster you are running: branches, classes, schedules, and students can be entered by hand in one afternoon, with no import at all. What decides whether it fits is not the size of the school but whether you are still counting remaining sessions, chasing payments, and messaging parents one by one. That work does not shrink in proportion to student count — in a small school it is precisely what eats the owner's own time. Klasku's plan limits grow with the school: moving up a plan or adding student capacity never demands a change of system, and a second branch is created the day it actually exists. Data already entered never has to move again.

Question 5

How is this different from keeping a spreadsheet?

Accepted Answer

A spreadsheet records; Klasku executes. Attendance marked by a teacher deducts the student's remaining sessions right then, invoices are issued on the date you set, reminders leave on their own, and parents check their child's remaining sessions without asking the admin. The difference shows most when a number is disputed. In a spreadsheet, remaining sessions is a figure somebody typed; in Klasku it is the result of the attendance history, so it can always be traced back to the session that deducted it — including when that attendance is corrected. Klasku also separates who may see what: teachers see no amounts, parents see only their own children, branch staff see only their branch. A spreadsheet file shared with many people has no boundary like that.

Question 6

Is there a trial before subscribing?

Accepted Answer

Yes: 14 days free, no credit card. Signup is self-service from the signup page on klasku.id, and the moment it finishes your school has its own address along with a live tenant panel, Parents Portal, and Teachers Portal. What you put into the school during the trial is your own data — classes, students, schedules, invoices. When you pick a plan, that same school carries on: nothing is rebuilt, nothing is imported twice. Klasku messages your school's contact before the trial ends, through the same channels as every other message, rather than switching the portals off unannounced. If you do not continue, what stops is access — the contents of the school are not thrown away the day the date passes.

Question 7

Who uses Klasku inside one school?

Accepted Answer

Four groups, each with a surface of their own. Owners and admin staff work in the tenant panel on a computer browser; teachers use the Teachers Portal on a phone; parents use the Parents Portal on a phone; and the school has its own public page on klasku.id. What separates them is not the layout but the data boundary. Staff see what their role allows, teachers only the classes they teach, parents only their own children. All four read the same data, so the attendance a teacher marks this afternoon reaches parents without anyone copying it over. Adding people does not mean adding licenses to think about one by one: teachers and parents are invited from the tenant panel at no per-head cost, and what a plan counts is the number of staff seats and active students.

Question 8

Which kinds of courses is Klasku a good fit for?

Accepted Answer

Courses whose students come back on a schedule: tutoring and early literacy, music, languages, dance, swimming and martial arts, robotics, and one-on-one private lessons. Online classes work too, because a class can store its own meeting link. What decides the fit is not the subject but the shape of the money: if your students pay for a number of sessions — monthly, as a credit pack, or as a course with a fixed number of meetings — Klasku was built for exactly that. Private lessons use the same engine, only with a capacity of one. Programs in Klasku are separate from classes: one school can run Guitar, Violin, and Voice with their own report aspects and calendar colors, with many classes underneath. A school teaching two different fields therefore does not need two accounts.

Question 9

Does Klasku also provide online learning material?

Accepted Answer

No. Klasku runs the administration of a school — students, schedules, attendance, session packs, invoices, report cards, and parent messaging — rather than supplying material, quizzes, or a virtual classroom. For online classes, what Klasku stores is the meeting link, which it sends to parents on the morning of the session. That boundary is deliberate. Course schools already have their own way of teaching and usually already use a video meeting app they like; what has no home yet is the administrative work — remaining sessions, invoices, and keeping parents informed. Because it never touches how you teach, Klasku can be adopted without changing your curriculum or your teachers' habits. What changes is where attendance and invoices are recorded, and that can start with a single branch.

Question 10

What devices does it need, and must everyone be online?

Accepted Answer

A browser is enough: a computer or laptop for staff, and an ordinary phone for teachers and parents. There is no app to install from a store, no program that updates itself, and no special hardware to buy. An internet connection is needed to open a screen and to save — including when a teacher marks attendance in class. That is why attendance is kept light: one screen, one roster, one save. The parent and teacher portals can also be added to a phone's home screen so they open like an app. School data lives on the server, not on anyone's phone. A teacher who changes phones, an admin who switches laptops, or a lost device therefore takes no data away — access is revoked from the tenant panel, and the history stays intact.

Question 11

What language and currency does Klasku use?

Accepted Answer

Indonesian throughout the tenant panel, the Parents Portal, and the Teachers Portal, including the messages sent to parents. The currency is the rupiah, written out in full as Rp 1.250.000, so no figure has to be interpreted twice. Every date and time is computed in the Asia/Jakarta time zone — schedules, make-up deadlines, invoice due dates, and automatic issuing. Month names are never abbreviated in messages, so a due date cannot be misread. Klasku's own public pages come in two languages, Indonesian and English, but the contents of your school stay exactly as you entered them: class names, program names, and report card notes appear as written.

Question 12

If something stalls, who do I ask?

Accepted Answer

Our team, over WhatsApp — answered by a human, not a bot. The link sits on Klasku's public pages and inside the tenant panel, so a question does not have to wait for a ticket to be opened first. Inside the tenant panel there is also a short guide per screen for the questions that come up most during setup: the order in which to fill in the school, what each payment model means, and how to switch on message channels. What takes the most time at the start is rarely how a screen works — it is deciding the payment model for each class. So that decision is asked for at one clear point, when a student is placed into a class, rather than scattered across settings that are easy to miss.

Question 13

My student data still lives in Excel — is moving it painful?

Accepted Answer

It works, through CSV. From Excel: File → Save As → CSV UTF-8, then upload — Klasku detects the column separator and the header row by itself. .xlsx files are turned down on purpose, because Excel alters data as it saves: the leading zero of a phone number disappears and dates become numbers. Only valid rows are written; rows with a problem come back with a reason so you can fix them. A CSV template can be downloaded from the import screen so the column names match from the start. All you really need is the student's name, the parent's mobile number, and the class; the rest can be filled in later without repeating the import. The import runs row by row, not as one all-or-nothing file. Rows with a broken number or an unknown class come back each with its own reason, and the rows that passed are already in — so a 300-student file never fails outright because of three bad lines.

Question 14

How do I start using Klasku?

Accepted Answer

Sign up yourself from the signup page on klasku.id: your school's name, the owner's name and contact number, then a plan. The school is created immediately with an address of its own, and the 14-day trial runs without a credit card. Everything after that happens in the tenant panel through a browser: create branches, programs, and classes; write the schedule patterns; then enter students and their families — by hand for a small school, or in one go through a CSV upload when the list is already long. Signup does not wait for our team to verify anything by hand: the school is born active and can be filled in right away. The form is protected by a bot check so school names and addresses are not consumed by junk registrations.

Question 15

How long until my school is actually running?

Accepted Answer

One afternoon is enough for a single-branch school. The smoothest order: branches → programs and classes → schedule patterns → students and their families → place students into classes with their payment model → invite teachers → switch on message channels. The step that matters most is placing students into classes, because that is where the payment model is chosen. A placement without a model is refused — exactly so that no student can attend without a pack to deduct the session from. A schedule only has to be written once as a pattern: sessions up to 90 days ahead are born from it by a daily check. So "the school is running" does not mean you filled in a calendar date by date — it means the pattern is right.

Question 16

What data do I need to prepare before starting?

Accepted Answer

Three things are enough to run: the student's name, the parent's mobile number, and the class the student belongs to. The rest — date of birth, address, nickname, notes — can be completed later without redoing anything. On the school's side, what has to be decided first is the list of branches, the list of programs, and the classes with their schedule patterns. The decisive choice is not the data but the payment model of each class: recurring monthly, a credit pack paid up front, or a course with a fixed number of sessions. A parent's mobile number is more than a contact field in Klasku — it is the identity used to sign in to the Parents Portal and the destination of every message. That is why a number can be changed at any time but never emptied: a student with no number is a student who cannot be told about an invoice.

Question 17

Some of my import rows were rejected — do I start over?

Accepted Answer

No. The import runs row by row: the ones that passed are already in, and the ones with a problem come back each with its own reason. Fix only those rows and upload again — students already imported are not duplicated, because the same student is recognized from their name and number. The most common reasons for rejection: a mobile number that is not a valid Indonesian number, a class name that does not match any class in the school, or an empty required column. The CSV template from the import screen prevents the first two, because the column names already match. Klasku deliberately refuses .xlsx files and accepts CSV only. Excel alters data as it saves — the leading zero of a phone number disappears, dates turn into numbers — and an import that accepted such a file would enter 300 students with wrong numbers without a single warning.

Question 18

Are my old invoices and payments moved over too?

Accepted Answer

Not automatically. What the CSV import brings in is students and their families; the invoice history of previous years stays in your old records, and that is usually the practical choice — old bookkeeping does not need rebuilding for you to start invoicing next month. What does need to move is the state of TODAY: a student with sessions left is given a credit pack the size of that balance, and money parents have already put down is recorded as a deposit into the family wallet. Old arrears you still intend to collect become manual invoices with their own due dates. Those three routes are not workarounds but the everyday mechanics, so the numbers stay alive: remaining sessions are deducted by attendance like any other pack, deposits are spent when paying, and manual arrears are picked up by the automatic reminders.

Question 19

What if my school has more than one branch?

Accepted Answer

Branches are created from the tenant panel, and from then on students, classes, staff, schedules, and invoices belong to a branch of their own. The Basic plan is built for a single branch; a school with several branches uses the Pro plan. A branch is more than a label. Staff can be restricted to their branch, reports can be read per branch, and an invoice never crosses branches — a family with children at two branches receives two invoices. A branch can be added at any point, including a year after the school started. The first branch's data does not move, and a student who transfers is simply placed into a class at the new branch — their attendance and payment history stays attached to them.

Question 20

How do I add admin staff to the system?

Accepted Answer

From the users menu in the tenant panel: invite the person, pick their role, and restrict them to a branch if needed. Staff sign in with their own email and password, rather than sharing the owner's account. The number of staff seats follows your plan, and extra seats can be bought without moving up a plan. Teachers do not take a staff seat: they are invited from the Teachers menu and sign in to the Teachers Portal with a mobile number plus a PIN. A shared account passed around is the fastest way to lose track of who changed what. So Klasku separates the person from the role: revoking a staff member's rights does not erase their work, and a recorded payment still names who recorded it.

Question 21

I am starting mid-semester — what should I watch out for?

Accepted Answer

Two things: each student's remaining sessions, and the invoice issue date. A student with meetings left is given a credit pack the size of that balance, so attendance starts deducting from the right number. A student on a monthly subscription is simply placed into a class with a monthly pack. For invoicing, set the school's issue date first, then decide whether the first invoice is prorated. The current month you already billed outside the system is simply skipped — automatic issuing only applies to the next period. Klasku never forces a school to start at the top of an academic year. Because a pack belongs to a student in a class rather than to the school calendar, students may join at any time with different balances without making the arithmetic messy.

Question 22

My system runs on credit packs or quotas, not monthly tuition — can it work?

Accepted Answer

That is exactly our specialty. Pick a credit pack or a monthly quota per class, and for a course whose number of sessions is already fixed, pick fixed-session classes. Attendance deducts a session automatically, the balance and validity window count themselves down, and parents can check the sessions they have left from their own phone. A credit pack may have no expiry at all — an eight-session course paid up front will not expire before the class even runs. A monthly pack works the other way around: the quota belongs to the current period and does not roll over into the next one. Remaining sessions are never typed by a human. Klasku keeps them as a consumption history — one row per attendance mark — so the balance can always be traced back to the session that deducted it, and correcting the attendance corrects the balance with it.

Question 23

What is a session pack in Klasku?

Accepted Answer

A session pack is how Klasku ties money to attendance: a student holds a pack containing a number of sessions, and attendance marked Present consumes one session from it. The pack belongs to the STUDENT in the class they were placed into, not to the class itself. That is why remaining sessions are not a figure an admin maintains. It is the result of a consumption history — one row per attendance mark — so every deduction traces back to the session that caused it, and correcting attendance repairs the balance without a manual adjustment. This single engine is what lets every school run a different payment model without a second system: all that changes is how a pack is refilled — renewed every period, or bought up front and used until empty — while attendance, invoicing, and the balance display behave exactly the same.

Question 24

What is the difference between a monthly pack and a credit pack?

Accepted Answer

A monthly pack recurs: its session quota belongs to the running period, its invoice is issued on the school's issue date, and unused sessions do not roll over into the next month. A credit pack is bought up front for a number of sessions, used until it is empty, and is not renewed automatically. Credit applies in the class the pack was sold for, so a student in two classes holds a pack for each — and a balance in one class is never quietly spent by the other. For a course whose session count is fixed, the class is set as fixed-session and the pack is born exactly that size. Both may live side by side in the same school, even for the same student in different classes. What determines the refill style is the shape of the CLASS — continuing or fixed-session — not one global setting that forces the whole school into one mold.

Question 25

A student's sessions run out mid-term — what happens?

Accepted Answer

That student's attendance is locked until the pack is refilled. The attendance screen disables their row and states the situation, and forcing a save is still refused, naming the student — so no presence is ever recorded without a session to deduct it from. For a continuing class, the student's card offers a new pack for sale. For a fixed-session class, an empty pack means the student has finished instead: the state shows as Completed in green, with no refill prompt and no alarm. Two things still work while a pack is empty: correcting attendance that was already saved, and marking a student who came in on a make-up right — that session was paid for earlier. The lock runs at both attendance doors, the tenant panel and the Teachers Portal, and is checked before the attendance row is written. A quota rule guarded at only one door has drifted in this product before, so both now read the same checker.

Question 26

Must a credit pack have an expiry date?

Accepted Answer

No. Expiry is an optional checkbox when the pack is sold: fill it in if the school wants the credit to lapse on a given date, leave it out if not. A pack with no expiry lives until its sessions are used up. If the expiry date does pass, the pack's status changes to expired through a daily check — not the moment somebody happens to open the screen. A student with an expired pack lands in the same state as an empty one: attendance is locked until there is a new pack. Fixed-session classes deliberately use credit with no expiry: an eight-session course paid up front must not lapse merely because the class started a month late. The preset numbers come from one place, so three screens that sell packs cannot use different session counts.

Question 27

A student joins mid-month — is the invoice the full amount?

Accepted Answer

Not necessarily. The first invoice of a monthly pack can be prorated — per remaining session or per day, depending on the school's setting — and the basis of that calculation is frozen as a note on the invoice, so it can still be explained months later. The order of calculation is the same for every recurring invoice: prorating first, then automatic discounts, then the family wallet balance if it is used. Because the order is fixed, two admins cannot produce different figures for the same case. The next period returns to the full amount by itself, because prorating only ever touches the FIRST invoice of a pack. Monthly renewals are issued by the daily check on the school's issue date, with a guard so one pack-period is never billed twice.

Question 28

Can I give sibling discounts or run a promo?

Accepted Answer

Yes, through discount rules the school sets itself: siblings, a discount for paying up front, students enrolled in more than one class, and a date-limited promo on the first invoice. The default is empty — with no rules, no discount is ever born quietly. Discounts do not stack: when one invoice matches two rules, the single largest value applies. Manually typed invoices are untouched by automatic rules, so a one-off concession can be given without changing the school's rules. The discount value and its note are frozen onto the invoice when it is issued. Changing a rule next month therefore never rewrites invoices already out there — the archive keeps explaining the amount that was actually charged at the time.

Question 29

My course is just 8 meetings and then it ends — is that supported?

Accepted Answer

Yes. The class is set as fixed-session with its number of meetings, and a student's pack is born exactly that size: paid once, with no expiry and no automatic renewal. When the last session is used, the student does not enter an emergency state. Their card shows Completed in green — no refill prompt, no alarm — because an empty pack in a class like this means the student has graduated, not fallen behind. The course session count is written on the class, not retyped every time a pack is sold, so three screens that sell packs cannot use different numbers. If the course is extended, that figure changes in one place and the next pack follows it.

Question 30

My student attends two classes — do the packs merge?

Accepted Answer

No, and that is the right answer. A student in two classes holds one pack per class, because the price and the session count belong to that class. Attendance in class A deducts the class A pack and never touches the balance in class B. On screen, each class has its own pack card with its own balance and state — so a student can hold a healthy pack in one class and an empty one in another without either number masking the other. Parents see the same separation in the Parents Portal. Credit spendable across classes sounds generous, but it erases the meaning of a balance: there is no longer a single answer to how many meetings are left in this class. So Klasku refuses it as a shape, not as a setting that could be switched on.

Question 31

How do I refill a student's empty pack?

Accepted Answer

From the student's pack card in the tenant panel: sell a new pack, pick the number of sessions, and the invoice is issued from there. For monthly packs there is nothing to touch at all — the next period's renewal is issued on the school's issue date. A pack that is still active cannot be overwritten by a new one; the system refuses and says the student still holds a running pack in that class. The only thing allowed is a new pack replacing one that is empty, expired, or absent. That refusal protects the meaning of the balance. Two active packs in one class leave a simple question — how many sessions are left, and which pack does the next attendance deduct — without a single answer, and that is exactly the sort of fog that sends an admin back to a spreadsheet.

Question 32

Can I switch from monthly to a credit pack partway through?

Accepted Answer

Yes, and what decides is the shape of the class: a continuing class offers both monthly and credit packs, a fixed-session class always uses credit the size of its session count. Changing the shape of the class changes the options offered the next time a pack is sold. A pack already running does not change with it — it finishes under its own rules. So the switch happens on the NEXT pack, and no student suddenly loses sessions they already paid for. The two engines may live side by side in the same school, even for the same student in different classes. There is no global setting forcing the whole school into one mold, because a private guitar class and a regular language class are rarely paid for the same way.

Question 33

How are private one-on-one lessons handled?

Accepted Answer

Like any other class, only with a capacity of one. A private class has its own schedule, teacher, and session pack; attendance deducts a session, an excused absence grants a make-up right, and the invoice comes from the same pack. A credit pack usually fits best here: the parent buys ten meetings, the balance drops each time the student comes, and rescheduling demands no manual arithmetic because what is counted is sessions, not dates. Because class capacity is checked at scheduling time, a private class cannot be overfilled by a misplaced student. And when the lesson time is moved, the moved session is still the same session — not a new one that deducts twice.

Question 34

Can parents see their child's remaining sessions themselves?

Accepted Answer

Yes, from the Parents Portal on a phone, without asking an admin. What they see is not a figure somebody typed but the result of the attendance history: each presence deducts one session, and the card names the child and the class it refers to. A family with more than one child sees a separate card per child per class, so no numbers blend together. The attendance history underneath explains how the figure got there. Opening the balance to parents is the cheapest way to cut questions to the admin — and the most honest one, because the number a parent sees is exactly the number the school invoices on.

Question 35

Where do registration fees and book charges go?

Accepted Answer

Into manual invoices, separate from session packs. One-off charges — registration, uniforms, books, exam fees — are created as their own invoice at any time, with their own due date. Manual invoices are untouched by automatic discount rules, so a sibling discount does not quietly cut the price of a textbook. If a concession really is intended, its value is written on that invoice directly. The separation keeps reports readable: recurring revenue from session packs does not blend with one-off charges, while due-date reminders still run for both through the same pipeline.

Question 36

A student is excused — is that session lost or can it be made up?

Accepted Answer

Not lost. Attendance has three marks: Present deducts one session from the pack, Absent burns one, and Excused deducts nothing — it grants a make-up right instead, with a deadline your school sets. A make-up right is booked into a suitable session of another class. If the student attends the make-up, the right is used; if they are absent, it is burned; if they are excused again, the booking is canceled and the right returns to available as long as its deadline has not passed. Because attendance is what consumes a pack, the make-up right is born from that same single tap — staff never have to track owed sessions somewhere else. Each right carries its own state (Available, Booked, Used, Expired), so the parent question "how many sessions does my child have left?" has exactly one answer.

Question 37

Attendance was marked wrong — can it be corrected?

Accepted Answer

Yes. A school admin may correct attendance at any time from the tenant panel, and the correction repairs the pack consumption with it: the old consumption row is replaced rather than stacked, so the student's balance is right again without a manual adjustment. Teachers themselves can only fill in attendance on the day of the session; outside that day the screen is locked and correcting becomes the admin's job. The history records who marked what, so "who took attendance here?" has an answer. Because attendance is pack consumption, correcting attendance means correcting money too: one stray tap deducts a session nobody used, and the parent sees the same number on their phone. That is why the correction path is kept open — even when the student's pack has already run out.

Question 38

A class is canceled — does the session still deduct the pack?

Accepted Answer

No. A canceled session, whether because of a school holiday or because the teacher could not make it, consumes nobody's pack, and any quota already spent is restored. If the school switches on compensation, students whose session was canceled receive a make-up right, and parents are told through the message channels that the session is off. Deleting a holiday date restores the sessions that were canceled, so a wrong date is not permanent damage. Klasku treats a holiday as an event on the SESSION rather than as a deletion of the schedule: the pattern stays intact, the calendar keeps showing that date as a holiday, and the following weeks do not shift.

Question 39

Is attendance marked by teachers or admins?

Accepted Answer

Both can, with different time limits. Teachers mark their class from a phone on the day the session runs; outside that day the screen is locked and says why. School admins may fill in and correct attendance at any time from the tenant panel. A substitute teacher gets the same right as the original teacher for that day, so a class whose teacher is away is still marked on time. The history records who marked what. The split follows the consequence, not the hierarchy: attendance deducts a student's pack, so presence marked days later changes money with nobody checking. Late marking therefore stays with the admin, who is accountable for the invoice anyway.

Question 40

How long does a make-up right stay valid?

Accepted Answer

Until the deadline the school sets itself, counted from the date of the missed session — fourteen days by default. A school that wants it looser or stricter simply changes the number in settings. Each right carries its own state: Available, Booked, Used, or Expired. A right past its deadline expires through the daily check, not the moment somebody happens to open the screen. The deadline is a school setting rather than a Klasku rule, because it is the school that pays for the room and the teacher's hours. What Klasku guarantees is only this: a right that exists never disappears quietly — its state is always readable on the student's card.

Question 41

How do I book a student into a make-up class?

Accepted Answer

From the student's make-up right: pick a suitable session in another class, and the student joins that session as a make-up attendee. The target class's capacity is checked at booking time, so a full class cannot be overfilled. Parents are told the make-up schedule through the message channels, and the session appears in the child's schedule in the Parents Portal. If the student attends, the right is used; if absent, it is burned; if excused again, the booking is canceled and the right returns to available while its deadline holds. A make-up attendee can still be marked even when their pack is empty, and that is not a loophole: the session they are attending was already paid for through the one they missed. Charging for it twice is exactly what makes a quota system lose parents' trust.

Question 42

A student shows up in a class that is not theirs — how do I record it?

Accepted Answer

Through the make-up route, not by adding them to that class's roster. A student can only be marked in a class they are enrolled in, because that is where the pack that deducts the session lives. If the move is permanent, the action is not attendance but placement: the student is placed into the new class with a payment model, and the old enrollment is ended. Attendance history in the old class stays intact. This boundary is what keeps remaining sessions accountable. Presence recorded in a class without a pack is a meeting that was never deducted from anywhere — and at the end of the month it surfaces as a gap nobody can explain.

Question 43

Can I see a month's attendance summary for a student?

Accepted Answer

Yes. Attendance history is available per student, per class, and per date range, with the status of every session. On the student's card the summary sits beside their pack balance, so two numbers that explain each other are read together. On the Pro plan, lists and reports can be exported to a spreadsheet file straight from the screen showing them — useful when a school has to attach an attendance summary to a report or hand it to a parent. A Klasku summary is not recalculated from memory: it is the same list of events that deducted the student's pack. So attendance figures in a report and the balance on a student's card cannot tell different stories.

Question 44

A student does not show up without telling anyone — is the session lost?

Accepted Answer

Yes. Absent burns one session from the pack and grants no make-up right — that is the difference from Excused, which deducts nothing but grants a make-up right with a deadline. If word arrives late and the school decides to accept it, the admin simply corrects that mark to Excused. The correction repairs the pack consumption and creates the make-up right, with no manual adjustment anywhere else. Separating Excused from Absent is a money decision, not a discipline policy: one returns the session to the student, the other acknowledges that the seat and the teacher's hour were already spent. Because both are a single tap, staff never track owed sessions elsewhere.

Question 45

My class has 20 students — do I mark them one by one?

Accepted Answer

No. There is a mark-everyone-present button, after which you only change the students who are excused or absent. One save for the whole class, and every student's balance is deducted from that moment. Students whose pack is empty or expired are left out of that button and their row is disabled with their state spelled out, so no presence is recorded without a session to deduct it from. The rest saves as usual. That check runs at both attendance doors — the tenant panel and the Teachers Portal — and runs before the row is written. A quota rule guarded at only one door has drifted in this product before, so both now read the same checker.

Question 46

Where does the payment money land?

Accepted Answer

Online payments are processed by a licensed payment gateway, then passed on to your school's bank account on its settlement schedule. Cash and bank transfers can still be recorded by hand. An invoice paid through the gateway turns paid the moment the payment is confirmed, without staff reconciling bank statements line by line. The default is one invoice per student; a school that switches on family consolidation receives one sheet per family per branch, itemized per child. Klasku separates money COMING IN from money PASSED ON. Every payment carries its own trail, and a payout to the school's account is recorded as a separate event — so the gap between "the parent has paid" and "it is in our account" can always be explained rather than guessed.

Question 47

When are invoices issued, and when are they due?

Accepted Answer

Recurring invoices are issued on the issue date the school picks itself (the 25th by default) through a daily check — not through a button somebody has to remember. The due date is that issue date plus the school's payment window, seven days by default. Outside that cycle, manual invoices can be created at any time: a new student's registration, teaching materials, or a pack sold mid-month. Invoices never cross branches — a family with children at two branches receives two invoices. Recurring issuing is guarded against duplication: one pack in one period can only ever produce one invoice, however many times the daily check runs. An invoice that totals zero because of a full discount is born already paid, and its message is skipped — not sent quoting Rp 0.

Question 48

Does Klasku remind parents who have not paid?

Accepted Answer

Yes, automatically. Reminders are scheduled at day offsets around the due date that the school sets itself — 7 days before, 3 days before, on the day, 3 days after, and 7 days after by default — and one invoice gets one reminder per offset, however often the check runs. Beyond that, staff can send bulk reminders from the invoice screen, or forward a single invoice over their own WhatsApp from its detail screen. Invoices past their due date are flagged Overdue, and the number on the navigation badge uses the same predicate as the screen it opens. The amount a reminder quotes is always the REMAINING balance, not the original total: partial payments and any family wallet balance already applied are deducted before the sentence is assembled. Chasing money that has already been paid is the fastest way to lose a parent's trust.

Question 49

How do parents actually pay?

Accepted Answer

From the Parents Portal: open the invoice, tap pay, and the payment link leads to a licensed gateway with channels such as QRIS and virtual accounts. A successful payment turns the invoice paid by itself. One payment attempt is valid for 60 minutes; after that the link expires and a new one is simply created. Cash or a direct transfer to the school can still be recorded by staff, including a partial payment — the invoice then sits as partly paid until the rest arrives. Proof of payment in Klasku is not the page shown after checkout but the confirmation from the gateway. So an invoice is never declared paid merely because a parent came back to the portal, and a check-status button is available for confirmations that arrive late.

Question 50

My invoices must include VAT — can it be calculated automatically?

Accepted Answer

Yes. The tax rate is set once in the school's settings, and every invoice issued afterward computes it itself: tax on the subtotal after discounts, added to the total, with its own line on the invoice the parent sees. The rate in force is frozen onto the invoice as it is issued. Changing the rate next month therefore does not rewrite old invoices — the archive keeps explaining the amount that was actually charged at the time. A school with no tax obligation simply leaves the rate at zero, and its invoices are born exactly as before — without an empty line to confuse parents. No rate ever appears because the system assumed one.

Question 51

Can I charge a late fee on overdue payments?

Accepted Answer

Yes, and it is applied by an admin deliberately — never automatically. The add-a-late-fee button only EXISTS on an invoice that is genuinely past due, prefilled with the amount from the school's settings and still editable case by case. A late fee raises that invoice's total, so it is reflected in the balance quoted by the next reminder and in the billed figures on reports. No late fee is ever born from a background check. Klasku's owner chose this deliberately: a fee applied by the system itself keeps running against the family who already spoke to the school and was granted leeway — and the school only finds out when the parent is angry.

Question 52

A parent wants to pay three months at once — how is that recorded?

Accepted Answer

As a deposit into the family wallet. The money is recorded as that family's balance, visible to staff and to the parent, and is then spent when the coming invoices are paid — partly or in full, as chosen at the moment of payment. The balance does not attach itself to invoices at random. Whoever pays chooses which invoice it closes, so money paid ahead is never quietly consumed by an invoice nobody meant. The family wallet is also home to overpayments and refunds: extra money does not become a note in an admin's head but a recorded balance that can be spent or returned. Its history explains every addition and every use.

Question 53

I have two children at one school — do parents get two invoices?

Accepted Answer

By default yes, one invoice per student. A school that prefers otherwise can switch on family consolidation, after which recurring invoices are issued as one sheet per family per branch, itemized per child. The invoice message names the children so parents know what the sheet covers. Consolidation never crosses branches: a family with children at two branches still receives two invoices, one per branch. What the school picks here is the billing format, not the arithmetic: each child's session pack stays separate and is still deducted by their own attendance. Consolidation only merges the sheet, so one payment settles everything at once.

Question 54

A parent pays half now — can that be recorded?

Accepted Answer

Yes. A partial payment is recorded as it is, the invoice sits as partly paid, and the remainder is computed. The next reminder quotes the latest balance rather than the original total. What is not allowed is recording a payment larger than the remaining balance — the amount field refuses it. Extra money the school genuinely received is recorded as a deposit into the family wallet, so it stays visible as that family's money. The overpayment ban is not fussiness: an invoice recorded as overpaid makes the revenue report count money the school has not earned yet. The family wallet solves both at once — the money is recorded, and the invoice stays honest.

Question 55

A parent asks for a receipt — do I have to make one by hand?

Accepted Answer

No. An invoice that is fully paid can be downloaded by the parent as a PDF receipt from the Parents Portal, complete with the invoice number, its line items, and the school's identity. Receipts are only issued for invoices that are genuinely settled. An invoice that is partly paid cannot be downloaded as one, because a document saying PAID over an unpaid balance is a document that lies. The details on the receipt come from the invoice itself — never retyped — so amounts, discounts, tax, and recorded payments cannot differ from what the school sees in the tenant panel.

Question 56

An invoice was issued in error — can I just delete it?

Accepted Answer

It is not deleted but voided or corrected. An unpaid invoice can be voided so it is no longer chased or reminded about; an invoice already partly or fully paid is corrected with a credit note for the amount to be reduced. A credit note records its reason and its author, then adjusts the invoice balance accordingly. If money has to go back to the family, its value lands in the family wallet and can be spent on the next invoice or refunded. Deleting an invoice would delete its trail too — including payments already recorded against it — and that is precisely the kind of hole that makes a school's books untrustworthy. Klasku chose corrections that leave a trail over deletions that look tidy on screen.

Question 57

Is there a report of income per month or per branch?

Accepted Answer

Yes. Klasku reports separate what was BILLED from what was COLLECTED, over a date range, and can be broken down per branch or per program — two figures often treated as one, when the distance between them is exactly that month's admin work. There is also an arrears report per student, so the list of who to chase does not have to be assembled by hand. On the Pro plan, all of it can be exported to a spreadsheet file. Report figures are derived from the same invoices and payments parents see, so there is no second version to reconcile. Overpayments are deliberately not counted as revenue — that money is a family's deposit, not yet the school's earnings.

Question 58

My classes repeat every week — do I re-enter them every month?

Accepted Answer

No. A schedule is written once as a recurring pattern — weekly (optionally every other week), specific dates each month, or the nth week of each month — and its sessions are then born from that pattern up to the end date you set. Sessions already born can still be touched one at a time: canceled for a holiday, moved to another hour, or handed to a substitute teacher. Time clashes and class capacity are checked when scheduling, not when the teacher is already standing in front of the class. Patterns and sessions are stored separately, and that is what makes changes safe: editing a pattern does not delete sessions whose attendance is already filled in, and canceling one session does not shift the following weeks. All times are computed in the Asia/Jakarta zone.

Question 59

How do I mark a public holiday or a school closure?

Accepted Answer

Holiday dates are recorded once in the tenant panel, and class sessions on those dates are marked canceled — including sessions born from a schedule pattern afterward. The calendar still shows the date as a holiday, not as a day that vanished without explanation. Canceled sessions do not deduct student packs, and if compensation is switched on, the students receive a make-up right. Deleting the holiday date restores those sessions. Klasku chose to create holiday sessions in a canceled state rather than not creating them at all: a session that never existed cannot be restored when the date turns out to be a typo, and a gap in the calendar with no explanation always reads to an admin as breakage.

Question 60

A teacher cannot make it — who arranges the substitute?

Accepted Answer

The teacher reports it from their phone, the admin decides. From that report the admin can appoint a substitute teacher for the session or cancel it; teachers never call off a class unilaterally. The substitute sees the session in their own schedule and can fill in its attendance. If the session is canceled instead, it follows the holiday path: no pack is deducted and parents are informed. A teacher can also withdraw their report while it is still undecided, and the decision is sent back to them. The decision deliberately stays with the admin because one session touches room capacity, other teachers' schedules, and students' make-up rights at once. What Klasku automates is the consequences — restored quota, notifications, and make-up bookings — not the judgment call.

Question 61

How does Klasku stop a teacher from being booked in two places at once?

Accepted Answer

A teacher's availability is judged on the PERSON, not on the class. Saving a schedule that would have one teacher in two overlapping sessions is refused, including when the two classes sit at different branches. Room and class capacity clashes are checked at scheduling time as well, not when the teacher is already in front of the class. What is compared is the hours, so back-to-back classes may still be taught by the same person. Checking at the person level matters for part-time teachers working across branches: a schedule that only knows its own branch will wave through exactly the clash that happens most — and it surfaces on the day of the session.

Question 62

The class is full but people still want in — is there a waitlist?

Accepted Answer

Yes. A prospective student joins that class's queue, and once a seat frees up, staff offer it to whoever is at the front. The offer is sent to the parent through the message channels with a deadline to reply — three days by default, adjustable per offer. An offer not answered by its deadline expires, and the person returns to the back of the queue with the attempt recorded. Offers are always a staff decision, never automatic: a free seat has often already been promised in a conversation the system knows nothing about. Class capacity is guarded from the other direction too — it cannot be lowered below the number of students already active in that class. A capacity smaller than its contents makes every screen that reads it report an impossible state.

Question 63

Can my online classes be managed in Klasku too?

Accepted Answer

Yes. A class is marked as online and stores its own meeting link. On the morning of the session that link is sent to parents through the message channels, so no link drowns in a chat group the night before. Everything else works as in a face-to-face class: teachers still mark attendance, sessions still deduct packs, and an excused absence still grants a make-up right. Klasku does not provide the video room itself — schools use the app they already know. The link lives on the class rather than being retyped every week, so the morning send always uses the same link the teacher holds. Changing it is done once and applies to every session after it.

Question 64

One meeting has to move — does the whole pattern change?

Accepted Answer

No. A session that has already been created can be moved to another time or date on its own without touching the class's schedule pattern, so the following weeks stay where they are. Teacher clashes and capacity are re-checked at its new position. The reverse holds as well: editing a pattern does not delete sessions whose attendance is already filled in. Patterns and sessions are stored separately — that is what makes a mid-semester schedule change safe. A moved session is still the SAME session, not a new one that doubles the deduction from a student's pack. That difference is invisible on the calendar, but it decides whether the balances are right at the end of the month.
