Once an invoice is sent via the Peppol network, it is automatically locked for editing or deletion. No changes can be made to the invoice — not even minor corrections like typos.
This is a security and compliance requirement under Peppol regulations.
If you notice an error after sending the invoice (e.g. in the address, amount, or description), use the credit note (correction invoice) option.
The system will automatically:
generate a credit note with the appropriate negative values,
allow you to send the correction via Peppol to the same recipient,
include the correction in your statistics and reports.
This procedure ensures full compliance with Peppol standards and maintains clear, auditable documentation.
