finisma is a free web tool for German B2B compliance. It does two things and nothing else: 1\. Convert any PDF invoice into a compliant ZUGFeRD (a.k.a. Factur-X) e-invoice: PDF/A-3 with an embedded EN 16931 XML payload that buyers' accounting systems can read automatically. 2\. Verify any ZUGFeRD/Factur-X PDF: structural checks (PDF/A-3, embedded factur-x.xml, AF markers, Factur-X metadata) plus the full parsed invoice in a clean human-readable view. No signup, no credit card, no integration work. Drop a file in the browser, get the result back. Built for the German E-Rechnungspflicht: every B2B company in Germany has to be able to receive e-invoices since 2025, and has to issue them from 2027 (>€800k revenue) or 2028 (all others).
