AIFE (French State Financial Information Agency), responsible for Chorus Pro, integrated Chorus Pro Factur-X as a hybrid format. On March 24th, 2020, FNFE-MPE and FERD released a joint version that is exactly the same as Factur-X 1.0 and ZUGFeRD 2.1.

After the alignment of Factur-X and ZUGFeRD with FERD, the .05 version of the Factur-X 1.0 documentation was published together with ZUGFeRD 2.1.

Factur-X is the name used in France in the German-French standard for electronic hybrid invoices, currently version 1.0. Fully compatible with ZUGFeRD 2.1 version and technically identical. For this reason, a single version of ZUGFeRD 2.1 / Factur-X 1.0 is mentioned. The mixed form contains a PDF file for users and XML data for further automatic invoice processing. The standard corresponds to the European standard EN 16931, which defines the standards and technical rules for electronic invoicing in Europe in order to ensure interoperability and legal compliance.

Factur-X aims to create added value for suppliers and billers by providing maximum information in a structured format. The standard is continuously developed and maintained under the auspices of the French National Forum for Electronic Invoicing and Public Electronic Procurement (FNFE-MPE).

Factur-X contains several standard data profiles to ensure the broadest acceptance by companies of all sizes:

MINIMUM: Corresponds to the minimum billing information required in Chorus Pro and corresponds to classic OCR header and manual validation data collection

BASIC WL: Compared to document level billing information, which is often required or useful for process automation for buyers

BASIC: Corresponds to the BASIC WL profile with basic line information that is required or useful for process automation buyers

EN16931: Corresponds to all billing information in the European standard EN16931

ADVANCED: Corresponds to the EN16931 profile with some additional billing data. This profile is under construction and will be published later.
