In brief

The eInvoice Validator for KoSIT validates your e-invoice with the official KoSIT validator and shows the report in plain language. The official KoSIT validator is the validation program of the German Coordinating Office for IT Standards for XRechnung. You drag the invoice into the app and read the result with every finding and its explanation.

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

The original report

You download the report exactly as the KoSIT validator wrote it.

XML and PDF

The app accepts XRechnung, Peppol BIS and ZUGFeRD and Factur-X as XML or PDF.

In practice

How others use it

The accounting team with a disputed invoice

The clerk drags the invoice into the app and reads the findings with their explanations. Then she downloads the report and attaches it to her query to the supplier.

The software company that creates invoices

Developers and consultants check their outgoing invoices against the rules a public authority applies, before the invoice goes out.
