When an invoice or an invoice line get the status definite, it is not possible anymore to modify the invoice. However, there is a possibility to correct a definite invoice. This happens in the form of a credit invoice. Just as a normal invoice, a credit invoice consists invoice lines.
- Click 'Financial' | 'Invoice' and go to the tab 'Definite'
- Open the desired Invoice
- Click 'Credit' and click [OK]
A credit invoice is now made with the next invoice number.
The original invoice can you see at the general tab of the credit invoice.
- Go to the tab 'Concept' and set the credit invoice definite.
Credit invoices can't be deleted, even if they have the status concept.
