Validation against the official rule sets
This validation uses the same Schematron rule sets as the official KoSIT validator: EN 16931 and the format-specific rules for XRechnung, PEPPOL, ZUGFeRD and ebInterface. The "Analysis" tab only looks at the structure — here the full rule set is applied.
Parties that receive your invoice, such as authorities or business partners, may apply additional rules of their own.
For this, your invoice is sent to our validation service, checked there and not stored — it is neither logged nor shared with third parties.
We run the service using Phorm by Philip Helger (open source, Apache-2.0).
No guarantee for official submissions — please validate independently before formal use. The issuer remains solely responsible for the tax correctness of any invoice.
