View an e-invoice

Upload an XRechnung or ZUGFeRD invoice and read it like an invoice on paper. Free, no sign-up.

The file goes over HTTPS to our API only for the view. We do not store it and delete it right after the request. More in the privacy policy (German).

What does the view show?

An XRechnung, or the XML inside a ZUGFeRD invoice, is hard for people to read. The view turns it into a page with seller, buyer, line items, taxes and payment details. At the top you switch between Overview, Items, further Information and the Attachments. With “Print to PDF” you save the invoice as a PDF.

It is based on the visualisation by KoSIT, the body that also publishes XRechnung. It is licensed under Apache 2.0 and reaches us through the Mustang Project. At the same time we check the file against EN 16931. If it is invalid, you see the errors at the top and below them everything that can still be read. The full check with suggested fixes is under Validate.

Frequently asked questions

Does the view count against my check quota?
No. The view has its own daily limit against abuse: 20 views a day without an account, 50 on the free plan, 500 on Automate and 2,000 on Scale.
Do you store my invoice?
No. The file stays on our server in Germany only for the duration of the request and is deleted afterwards, even if something goes wrong.
Which files can I view?
XRechnung in UBL and CII syntax, CII invoices under EN 16931, and ZUGFeRD 2.x and Factur-X as a PDF with embedded XML. A PDF without embedded XML is not an e-invoice; just open it in your PDF reader.
Can I build the view into my software?
Yes, with POST /v1/view of the REST API or the MCP tool view_invoice. The response holds cleaned HTML without script.
