How do I add admin staff to the system?
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.
