Peppol BIS 3.0 / KSeF XML Auditor

Paste a UBL Invoice XML document and validate it against Peppol BIS Billing 3.0 (EN 16931) structural and calculation business rules, plus optional country overlays for France, Poland, Belgium, Germany and Australia. Reports per-rule pass/fail with detail, and exports a Markdown report and a Policy Mandate JSON.

⚠ This auditor checks a curated subset of the EN 16931 / Peppol BIS 3.0 business-rule set — the core structural and calculation rules — not the full Schematron. A clean result here is an indicator, not a substitute for certified validation by your access point or PDP.
