Invoices in MAS9 are generated in two different scenarios, depending on the student’s chosen payment method:
1. Credit Card or ACH Payments - If the student is paying by credit card or ACH, the payment is processed automatically on the due date. A payment receipt is also sent to the student on the same day.
2. Cash or In-House Payments - If the student is paying by cash or through an in-house method, an invoice is automatically generated 7 days before the due date. This invoice is then sent to the student as a reminder.
