FAQ

What is a Peppol validator?

A Peppol validator checks whether a UBL XML invoice complies with Peppol BIS Billing 3.0 and EN16931 business rules. It runs schematron-based checks for schema issues, missing fields, invalid identifiers, and rule violations.

What is an e-invoice?

An electronic invoice (e-invoice) is a structured digital document exchanged directly between seller and buyer systems, not a PDF or scanned image. In Europe, e-invoices follow the EN16931 standard and are typically encoded as UBL 2.1 XML. They can be validated, processed, and booked automatically without manual data e

How do I validate EN16931 invoices?

Upload your UBL XML invoice above and run validation against EN16931 and Peppol BIS schematron rules. Errors and warnings are shown inline with rule references. For CII / Factur-X invoices, use our Factur-X validator.

What causes Peppol validation errors?

Common causes include missing mandatory fields (like seller/buyer identifiers or tax breakdowns), incorrect InvoiceTypeCode (BT-3), scheme ID mismatches on electronic addresses (PEPPOL-EN16931-R004), empty XML elements (PEPPOL-EN16931-R008), and calculation mismatches on line or document totals (BR-CO rules).

Can I validate Peppol credit notes?

Yes. Upload a UBL CreditNote XML file and it will be validated against the same Peppol BIS 3.0 and EN16931 rules. Peppol supports two approaches: a dedicated CreditNote document (code 381, positive amounts) or a negative Invoice (code 380, negative amounts). Both are valid.
