XRechnung is the standard for electronic invoicing for public contracting authorities and definitively implements Directive 2014/55/EU in Germany. The Coordination Office for IT Standards (Koordinierungsstelle für IT-Standards, in short: KoSIT) maintains and develops the XRechnung standard on behalf of the IT Planning Council. Furthermore, KoSIT coordinates the continuous development of XRechnung with assistance by experts from the Federal Government, the states and the municipalities. 

Further information can be found on the KoSIT website .

The current version of the XRechnung standard must always be used when issuing electronic invoices to the Federal Administration. Any other standard (e.g. ZUGFeRD 2.1.1 with the XRechnung profile as a purely structured XML file) can also be used, if it meets the requirements of the European standard for electronic invoicing (EN-16931), the Federal Government’s Regulation on Electronic Invoicing (E-RechV) and the Federal Government’s terms of use for the invoice submission platforms.
