The official rules
The check uses the rule sets that recipients and invoice portals use as well: EN 16931, XRechnung, Peppol BIS Billing and Factur-X / ZUGFeRD. The tool tells from the invoice itself which of them apply.

Your file stays with you
The check and the display run entirely in your browser. The invoice is not uploaded for it.
Read, print, correct
The content of the e-invoice is shown as a readable document. You can print it, save it as a PDF or open the invoice in the e-invoice generator and correct it.
Many invoices at once
Choose several e-invoices or a ZIP archive, or simply drop them onto the page. An overview shows the number, biller, amount and result of every invoice. Save the list as a CSV file for your accounting or print it as a validation report.
Find errors, open attachments
Every broken rule is listed, the common errors with a hint on what to do. The affected details are marked in the displayed invoice. Attachments of the e-invoice, such as delivery notes, can be opened and saved.
Check incoming invoices
Since 2025, businesses in Germany must be able to receive e-invoices. Check incoming invoices before you book and pay them, and ask the sender for a corrected version if there are errors.
