Invoice by Juros-AI builds the United Kingdom e-invoice — EN 16931 UBL (Peppol BIS 3.0) — and checks it against the official schema on your own machine before anything is sent. Invoice by Juros-AI reads any invoice into clean data and is adding compliant invoice creation — the same rules on this page, built into the engine, run entirely on your own hardware. No cloud, nothing uploaded, no figure invented.
Every generated invoice is validated on your machine against the official artefacts — the OASIS UBL/CII schemas, the CEN EN 16931 schematron, Peppol BIS 3.0, KoSIT XRechnung, FatturaPA, KSeF FA(3) and the Peppol PINT packages. This page is a reference for build scoping; it is not legal or tax advice.
