A frequently requested function from our customers was that customer invoices could be offset against credit notes. This function has now been integrated into the detailed view of invoices.
The prerequisite for this function is that the invoice is not in draft status (e.g. sent, due, etc.) and that both the invoice and the credit note have the same address.
This offset is treated by the system as a payment and is also booked to an auxiliary account 9942. This is only for technical reasons for the correct calculation of the open items list.
The accounting is done automatically as usual and you do not have to do anything else.
