The Prepaid lessons are completely automated and maintained by ADI-diary.NET. It calculates all the funds for all the pupils and notifies you of remaining amounts.

First create an invoice

1. Go to Payments Menu and click New Invoice
2. Check the Pupil edit box and select a different pupil if necessary
3. Select Prepaid
4. Set Payment Method
5. Scroll the hours up and down. (The amount will be recalculated according to the pupils's rate)
6. Click Create

The Invoices dialog box appears, which will display newly created Invoice with the current date. Change the date if necessary. The lessons list will be empty.

Click Exit button. Insert some lessons for the pupil. Any lesson that is inserted on the invoice creation date or in the future is automatically inserted in the list, notifying you of the remaining funds left in the pupil's account.

When the amount is exhausted, ADI-diary.NET closes the invoice and never inserts any more lessons into the list. If an invoiced lesson is deleted, ADI-diary.NET checks against all invoices of the pupil and opens the invoice again to use up the funds. The cash lessons are not checked against the invoices.
