As answered by people managing Codegres.org and aiDoks.eu.
aiDoks.eu's answer:
aiDoks covers the whole EU e-invoicing workflow — generate, validate, and convert — in one free web tool, across formats that usually require separate tools: PEPPOL BIS 3.0, XRechnung (UBL & CII), Factur-X/ZUGFeRD, Spanish Facturae and Estonian e-arve. Validation runs the official schematron rule sets used by KoSIT, PEPPOL and national authorities, including country CIUS rules for Germany, France, Romania, the Netherlands, Portugal and Spain. And you can upload an existing PDF invoice and let AI extraction fill the e-invoice for you.
aiDoks.eu's answer:
Most free alternatives do one thing: a validator here, a ZUGFeRD library there — and many require signup, watermark the output, or assume developer skills. aiDoks is built for non-technical users: no signup for the first use, watermark-free XML, plain-language validation errors with rule IDs, and format conversion (PDF → e-invoice, CII ↔ UBL, Facturae → UBL, e-arve → UBL) that standalone validators don't offer. Pro is $4.85/month for unlimited use — a fraction of typical e-invoicing platform pricing.
aiDoks.eu's answer:
Small businesses, freelancers and accountants in Europe who need to send or check compliant e-invoices without an ERP system — especially in Germany, France, Belgium, Spain and Estonia, where e-invoicing mandates are already in force or arriving (France's B2B mandate starts 1 September 2026). Also useful for developers and consultants who need a quick validator against the official rule sets.
aiDoks.eu's answer:
Europe's e-invoicing mandates are rolling out country by country, but the tooling was built for large enterprises — small businesses were left choosing between expensive platforms and raw XML. aiDoks started as a simple free validator and grew into a full toolset: generators, validators and converters for every major European format, with AI-powered PDF extraction so nobody has to type an invoice twice. It's built in Latvia and available in seven European languages.
aiDoks.eu's answer:
Java 21 with Spring Boot on the backend, Angular on the frontend, PostgreSQL for storage. Validation uses ph-schematron with the official EN 16931, PEPPOL, KoSIT and national CIUS rule sets. PDF invoice extraction is powered by Azure AI Document Intelligence.
