What it does
Validate a hosted or pasted EU e-invoice against EN 16931 and the KoSIT Schematron business rules — hundreds of rules beyond the XSD, with exact rule-ID and element evidence
Validate one public-sample or pasted EU e-invoice (XRechnung, ZUGFeRD/Factur-X CII, Peppol BIS Billing 3.0, or UBL) against the EN 16931 semantic model plus the national/Peppol Schematron business rules with exact rule-ID, severity, and element evidence, or compare two same-lineage invoices, with a clear structural-conformance-versus-legal-validity boundary and the pinned config version named in every result.

E-Invoice Check questions
Scope and boundaries for E-Invoice Check.
01What does E-Invoice Check actually check?
Validate one public-sample or pasted EU e-invoice (XRechnung, ZUGFeRD/Factur-X CII, Peppol BIS Billing 3.0, or UBL) against the EN 16931 semantic model plus the national/Peppol Schematron business rules with exact rule-ID, severity, and element evidence, or compare two same-lineage invoices, with a clear structural-conformance-versus-legal-validity boundary and the pinned config version named in every result.
02What does it never do?
It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.
03What does it cost?
Nothing. Every published app is free to use with fair-use rate limits.
04Can my assistant connect directly?
Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/einvoice-check/mcp. Marketplace listings are conveniences over the same live engine.
