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.
Scope & reliance — 🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only. Embedded rates, thresholds, and regulatory citations are static reference values that may age — verify against current primary sources and your own data before relying on any output for commercial, legal, or compliance decisions. Deterministic logic · no inference · zero PII · CC BY 4.0.
