When a credit invoice is allocated to an invoice and it is sent, the program asks whether to make payments for the invoice and the credit invoice. If the user answers Yes, a payment corresponding to the amount of the credit invoice will be made on the original invoice, and the credit invoice will be marked as paid.
However, payments for the credit invoice are only made when certain conditions are met:
- The credit invoice must be allocated to the original invoice.
- The invoice must have at least as much open balance as the credit invoice.
If these conditions are not met, payments must be made manually on the invoices.
