Our ERP team needed to test outbound Factur-X generation against EN 16931. The validator gave us machine-readable error reports we could feed straight into our QA pipeline. Cut the test cycle from 2 weeks to 3 days.

The PA-specific business rules are the differentiator. Other validators just check XSD. This one tells us we'll fail on a French tax-amount-mismatch rule before the PA does. Saves a roundtrip every time.
