About FactureJuste

FactureJuste exists because existing e-invoice validators return cryptic rule codes — "BR-CO-15 failed" — without ever saying what's wrong or how to fix it.

We do one thing: check that a Factur-X, UBL or CII invoice complies with EN 16931 and the French rules, and explain every error in plain language — French and English — with a concrete fix. Free, no signup, and your files are never stored.

FactureJuste is built by Colin Lynch, a payments-compliance specialist. Validation runs against the official schemas and rule sets (the exact rule-set version is shown at the bottom of every report).

What FactureJuste is not: a registered transmission platform (Plateforme Agréée), accounting software, or tax advice. For transmission, you choose your own accredited platform.
