How to issue a credit note (cancellation invoice)

A credit note is a cancellation document that cancels or amends the original invoice. The law does not allow an issued invoice to be simply deleted — a credit note is issued specifically for the purpose of correction. In accounting, the amounts are deducted using negative values.

Procedure

1. Open the original invoice (Documents → Invoices).
2. Click on the ⋮ menu in the top right-hand corner and select “Issue credit note”.
3. The items are copied with negative amounts — you can edit them (e.g. if you are only refunding part of the amount).
4. Save.

You can find all credit notes in Documents → Credit Notes. They have their own numbering sequence (e.g. DP20260001) and the amounts are displayed with a negative sign.
