Validate your e-invoices in CI — XRechnung, Peppol BIS, Factur-X. FatturaPA Q3 2026.

Compliance-as-code for EU electronic invoicing: a REST API, a CLI and a GitHub Action that run the published Schematron rules for Peppol BIS, XRechnung, Factur-X, UBL and CII. Every error comes with a plain-English explanation and the fix. FatturaPA (Italy / SdI) private beta opens Q3 2026.

We're explicit about coverage: see exactly what validates today and what's next. Built on the open Mustang / phive Schematron engines — the value here is the CI packaging, the error→fix mapping, and the upcoming FatturaPA coverage (currently in private beta).

Free tier: 20/hour on the web validator, 500/day & 5,000/month with a free API key. No credit card.

Never ship a broken invoice.

Add the Action to your workflow; the build fails — with the rule ID, the explanation and the suggested fix — before a rejected invoice (a scarto from the SdI, a refusal from Chorus Pro, a KSeF error) ever happens.
