What is an XRechnung?

An XRechnung is an electronic invoice in a structured XML format following the European standard EN 16931. Unlike a PDF it is made for software, not for people: opening the file directly only shows XML code.

Why am I receiving XML files instead of invoices?

Senders deliver XRechnungen as .xml files so that software can process invoice data. For receiving and sending obligations and exceptions, see our FAQ on obligations and deadlines.

How can I open and read an XRechnung?

Use our free XRechnung viewer: drag the file into your browser and read it like a regular paper invoice, or save it as PDF via the print dialog. The file stays on your computer; nothing is uploaded.

XRechnung, ZUGFeRD, Factur-X — what's the difference?

All three follow the same standard, EN 16931. XRechnung is pure XML (in two syntaxes: UBL or UN/CEFACT CII). ZUGFeRD and its French counterpart Factur-X are PDF files with embedded XML — you see an ordinary PDF, the machine reads the XML. Our viewer opens all three formats; for PDFs, see how to open a ZUGFeRD file.
