Peppol Invoice Validator

Precheck in the browser, then formal validation through the Tooltensor validator service.

Waiting for an XML file.
What this page is for
This page is for staged validation, not legal certification. It helps users see whether the invoice carries the expected structural fields first and then whether the formal validator reports EN 16931, Peppol BIS, or related XML-rule issues.
What people mean by Peppol validator
Users often search for Peppol validator or Peppol validation when they want to know whether an invoice XML file is only readable or whether it also passes deeper invoice rules. This page is built for that second question: staged validation from precheck into formal rule checking.
Best order to use it
The best order is: detect the file family if unclear, open the XML in the viewer if you need readable review, then run this validator when the question changes from "what is in this file?" to "does this file pass deeper invoice rules?"
What Peppol validation checks in practice
Peppol validation in practice means checking whether the invoice XML not only opens, but also aligns with expected structure, mandatory business fields, totals logic, and the deeper rule layer used in formal billing workflows.
What a failed result usually means
A failed result does not always mean the file is unreadable. It usually means the XML structure, mandatory business fields, totals, or standard-specific rules are not aligned strongly enough for formal acceptance. That is why readable inspection and formal validation should be used together.
