Free Factur-X Validator
Factur-X is France's standard hybrid e-invoice format for the upcoming B2B mandate (September 2026). It combines a visual PDF with embedded CII XML, compatible with Chorus Pro (B2G) and the new PPF/PDP ecosystem (B2B). French-specific fields like SIRET and code de service distinguish it from the German ZUGFeRD variant.
