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 extracts the embedded CII XML from a Factur-X/ZUGFeRD PDF and validates it against the official EN 16931 CII Schematron, and generates genuinely PDF/A-3b conformant Factur-X files (verified with veraPDF) — see /formats/factur-x for the full detail.
