When you send an invoice via Peppol, the UBL file is the only authoritative source.
The PDF is provided for visual reference only and is not used for processing.
What is taken into account?
- Bank account (IBAN): the value in the UBL is used
- Invoice number: only the number in the UBL is valid
- Payment, accounting, and VAT checks: processed exclusively based on the UBL
Any information shown in the PDF is ignored by client systems.
Always ensure that:
- The PDF matches the UBL exactly
- The UBL is treated as the single source of truth
