Factur-X
Factur-X is the French hybrid e-invoice format, technically identical to ZUGFeRD, that embeds structured EN 16931 data inside a human-readable PDF/A file.
Factur-X and ZUGFeRD are the same hybrid PDF-plus-XML approach developed jointly by France and Germany. A single file works as a readable invoice and as structured data, which suits cross-border trade between the two markets.
For a European AP team that receives from both German and French suppliers, being able to read either name transparently removes a whole class of format friction.
Cortena treats Factur-X and ZUGFeRD the same way and pulls their embedded data straight into coding.
