Zaamm displays the content of e-invoice files, runs basic arithmetic and completeness checks based on the European standard EN 16931 and creates UBL 2.1 invoice files from the data you enter.

Zaamm is not a certified e-invoicing provider, access point or validator, and it does not transmit invoices to anyone. The checks cover only part of the applicable rules; a file that passes them may still be rejected by an official validator, a tax authority or your business partner. The display is a convenience view; the invoice file itself remains the authoritative document.

Nothing on this site is tax, accounting or legal advice. Dates and rules shown for individual countries are a summary at the date stated on the page and may have changed.

The service is provided as is, without any warranty. You remain responsible for the invoices you issue, receive and archive.
