UBL invoice validation checklist before Peppol submission

Use this checklist before sending a UBL invoice. It is a practical review aid, not a replacement for current Peppol validation or your Access Point's controls.

Document identity

• Invoice ID is present and comes from the invoicing system.
• Issue date uses the required date format.
• Invoice type code and document currency code are present and appropriate.

Seller and buyer

• Seller and buyer legal names are populated.
• Required identifiers use the correct identifier type and value.
• VAT identifiers include the applicable country prefix when required.

Electronic routing

• Buyer and seller cbc:EndpointID values are present where required.
• Each EndpointID has the correct schemeID.
• The identifiers match the participants registered or agreed with the Access Point.

Invoice lines and totals

• At least one invoice line exists.
• The document line total equals the sum of line net amounts.
• Document allowances and charges reconcile with their totals.
• Total without VAT, VAT total, total with VAT and payable amount reconcile in sequence.
• Rounding and decimal precision are consistent with the applicable rules.

VAT and payment information

• VAT categories, rates and breakdowns match the invoice lines and document-level adjustments.
• If the amount due is positive, a due date or payment terms are provided when required.
• Payment and bank information reflects the real commercial arrangement.

Final checks

• Validate the regenerated XML, not an earlier copy.
• Review fatal findings before warnings.
• Keep the latest rejection report for comparison after resubmission.
