ADI-diary.NET counts all the fees paid by all pupils and deducts them from assigned invoices. The software also notifies you about the funds left in prepaid amounts.

When the prepaid amount does not have enough funds to cover the lesson, a dialog box appears, giving you the opportunity to do one of the following:

1. Select Top-up Invoice if pupil pays cash to instructor to cover for extra time.
2. Select ignore if you expect further payments from the pupil. The lesson will be inserted in the Invoice, showing an undercharge in totals. You can balance the charges later in the Balance Sheet by creating a Top-up Invoice.
3. Give complimentary time
