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).

Key features (bullet list for the gallery / "features" field)

* PDF → ZUGFeRD in ~30 seconds
* LLM-based field extraction (you review and correct before commit)
* EN 16931 validation built in
* ZUGFeRD/Factur-X viewer with parsed invoice display
* IBAN cross-check against the original document
* Uploaded files auto-delete after 5 minutes
* German servers, ISO 27001-certified data center
* Free for everyone, no
