Paid product · One-file app · Demo · eInvoice Viewer – Mustang Validator

In brief

The eInvoice Validator for Mustang validates your e-invoice with Mustang, the open-source validation program from the ZUGFeRD and Factur-X community, and shows the report in plain language. For a PDF, Mustang also checks the PDF itself against PDF/A-3.

Here, the validation runs through the validation service of this website. If you want to validate without the website, you get the app in the shop in an edition for the Validator Bridge on your own computer.

Features

What the app does for you

One drop zone for PDF and XML

The drop zone accepts ZUGFeRD and Factur-X PDFs as well as XML invoices in both CII and UBL syntax.

Clear messages when a file doesn’t fit

A PDF without an embedded invoice, such as a scanned document, is rejected with a clear message, and so is a file with the wrong extension or a file that is too large.

The original report as report.xml

A button above the report saves it exactly as the Mustang validator produced it.

A clear note for newer versions

If an invoice names a version Mustang does not know yet, Mustang checks against the older version, and a note above the report says so.
