Factur-X / ZUGFeRD validator (France & Germany)
France’s phased B2B mandate (2026–27) accepts Factur-X; Germany uses the ZUGFeRD variant.
Factur-X (France) and ZUGFeRD (Germany) are hybrid invoices: a human-readable PDF/A-3 with an embedded EN 16931 XML in UN/CEFACT CII syntax. They let one file serve both people and machines.
InvoiceHub validates EN 16931 today via the UBL syntax. CII validation and extracting/validating the XML embedded in a Factur-X PDF are on our roadmap — follow the docs for status.
