Open and read an XRechnung invoice

Open an XRechnung in UBL or CII and read it as a document: who it is from and to, every line, the VAT breakdown, the totals and how to pay. Each value links back to its line in the XML.

What the viewer shows

What it opens

  • XRechnung invoices and credit notes in UBL 2.1 and in UN/CEFACT CII, the syntax behind XRechnung CII and the XML of ZUGFeRD and Factur-X.
  • Dates in CII are read from their format code; a date in a format the viewer cannot read safely is shown as written, with a note.
  • A PDF cannot be opened: open the XML instead. Documents up to 5 MiB.

Viewing is not validating

A document that opens cleanly can still break the XRechnung rules. Validate it here, or in the XRechnung validator, to check it against the official rules.

Open the XRechnung validator

Questions

Which files can I open?
An XRechnung invoice or credit note in XML, in UBL 2.1 or UN/CEFACT CII, up to 5 MiB. The viewer also reads the CII XML of ZUGFeRD and Factur-X invoices, but it does not open PDFs.
Does opening a file check it?
No. Viewing shows what the document says; it does not decide whether it is valid. Use Validate this document to check it against the XRechnung rules.
What happens to my file?
It is sent to Ironfang's servers in the UK to be read, and the readable view comes back to your browser. Nothing is stored. Content-free request and security metadata, including your IP address, may be kept for up to 90 days.
Why are some parts not shown?
The readable view shows the invoice fields people need. Anything else in the document, such as extension content, is counted and named above the document, and the XML tab always has the whole file.
Can I get a PDF?
Use Print to print the readable view or save it as a PDF from your browser. The viewer does not convert XRechnung to a PDF invoice.
