Editing an invoice in OkiOki – what is allowed and what is not?

Am I allowed to edit an invoice in OkiOki?

Have you discovered an error in an invoice you have already created? Don’t panic — but the answer to the question "can I still edit it?" depends on the status of your invoice.

Sent invoices: not directly

Have you already sent an invoice via Peppol, or downloaded it to send by post? Unfortunately, you can no longer simply modify it. Once an invoice has been sent, it is legally binding. Belgian accounting law does not allow a sent invoice to be modified afterwards — regardless of whether it is an electronic or paper version.

The correct procedure is:

1. Create a credit note for the original invoice — this cancels it in a legally correct way.
2. Create a new invoice with the correct details.
3. Send the new invoice via Peppol or by post.

This way your bookkeeping remains accurate and you comply with legal obligations.

Invoices in draft mode: simply edit

Is your invoice still in draft? Then nothing has been sent yet and you can freely edit it. No credit note needed, no extra steps — just edit and send it when it is ready.
