Validate your Factur-X
Drop your PDF or XML: we read the Factur-X metadata (declared version, profile, PDF/A) and test the EN 16931 rules behind most e-invoicing platform rejections.
Why Factur-X invoices get rejected by certified platforms
Since 1 September 2026 every French VAT-registered company must be able to receive e-invoices in Factur-X, UBL or CII syntax compliant with the EN 16931 European standard. Rejections come from four causes: a plain PDF without embedded XML, a too-low profile (MINIMUM), inconsistent amounts across lines and totals (BR-CO rules), or missing Factur-X XMP metadata. This validator checks all four and tells you what to fix, rule by rule.
The tool analyzes your file in memory on a server hosted in France: the spec version declared by your software (XMP fx:Version), the profile (MINIMUM to EXTENDED), the syntax (CII or UBL) and every violated EN 16931 rule with its official code (BR-02, BR-CO-10…). Nothing is stored.
