Why these tools?
From January 1, 2025, companies in Germany are required to receive and process electronic invoices in XRechnung or ZUGFeRD format. For many accountants, developers, and small businesses, this raises daily practical questions:
- Is my XML file really EN 16931-compliant?
- Which mandatory field is missing because the portal rejected the invoice?
- What does this ZUGFeRD XML look like in human-readable form?
- How do I quickly convert my Excel data into a valid XRechnung?
These free tools answer exactly these questions – directly in the browser, without installation, without registration, and without your invoice data leaving our servers.
Validate XRechnung online (KoSIT-compatible)
Our validator checks all mandatory fields per EN 16931 and the German CIUS XRechnung 3.0. It recognizes both UBL 2.1 and CII formats and reports missing Business Terms with their official BT number. Functionally equivalent to a KoSIT Validator online – without local Java installation.

No account, no credit card – just enter data and download XML. For higher volumes or direct PDF-to-XRechnung conversion, the paid SaaS version is available.
Make ZUGFeRD XML readable
