EN 16931 format validation
Every incoming XRechnung is validated against the European EN 16931 standard. Missing required fields and wrong structures are detected immediately.
Validate XRechnung
Validate XRechnung with readable results instead of XML guesswork.
The public XRechnung validator checks uploaded XML and PDF files for format, totals logic, and required fields. It immediately shows German SMEs and tax advisors whether an invoice is ready for export, needs manual review, or is not an e-invoice. The file remains limited to that validation request and is not stored permanently.
The file is validated in memory only and is never stored.
Sum and tax logic
Does net plus tax equal gross? Do line items match the total amount? Automatic checks catch calculation errors.
Readable validation reports
Instead of cryptic error codes like BR-CO-10, you get clear guidance: what is wrong, which field is affected, and what to do next.

What does the public XRechnung validator check?
It checks format, required fields, totals, and tax logic, then classifies the result as valid, warning, invalid, or not an e-invoice.
Is the uploaded file stored?
No. The file remains limited to that validation request and is not stored permanently by the public validator.
Can I also validate a ZUGFeRD PDF?
Yes. The validator accepts XML and PDF files and detects whether they contain a supported structured e-invoice.
