How it works
Validate any UBL invoice in seconds
Three steps from upload to a clear, actionable report.
2. Run the rules
We check XML schema, EN 16931 semantic rules and Peppol BIS 3.0 CIUS.
3. Read clear errors
Each issue shows the rule ID, the affected line, and a human-readable fix.
What does the UBL validator check?
Our online UBL validator runs the same business rules used by official Peppol Access Points. Every invoice you upload is checked against the UBL 2.1 XML schema, the European e-invoicing standard EN 16931, and the Peppol BIS Billing 3.0 Core Invoice Usage Specification.
Validation covers schema-level errors (malformed XML, missing required elements), semantic rules (BR-01 through BR-CO-26: totals, tax categories, payment terms) and Peppol-specific identifier rules. Errors are returned with the exact rule ID, the affected line in your document, and a plain-language explanation so you can fix issues without digging through specs.
Whether you're an accounting software vendor preparing for German e-Rechnung, a French Factur-X implementer, or a Belgian supplier sending invoices through Peppol, GetUBL helps you ship compliant XML with confidence.
