Supplier information XRechnung

Since 27 November 2020, as an official contracting authority, KfW has been legally obliged to request electronic invoices in XRechnung format from its suppliers

What is an XRechnung?

Within the meaning of EU Directive 2014/55/EU, an XRechnung is an invoice that is issued, transmitted and received in a structured electronic format that enables automatic and electronic processing.

An XRechnung is a standardised format specification for an electronic invoice. From a technical perspective, an XRechnung is an XML-based data model. It is the German application specification of the European CEN technical standard data model and thus the national standard for public administration.

The XML file in XRechnung format represents the invoice. An invoice in PDF format or a scanned paper invoice does not meet the requirements of the E-Invoicing Ordinance (ERechV).
