eunormio turns your invoice data into a ZUGFeRD/Factur-X PDF/A-3 to EN 16931 — and validates every result before it is delivered.

What eunormio does

Generate e-invoices

From JSON or CII-XML plus your PDF, eunormio builds a ZUGFeRD/Factur-X PDF/A-3 that meets EN 16931.

Guaranteed valid

Every output passes an automated validation gate — anything that would not pass is never delivered.

Private by design

Invoice data and PDFs are processed only in memory and never stored. We keep just accounts and quotas.

Multiple input formats

Fill in a guided form, or hand over structured JSON or CII-XML — whichever fits your workflow.

Built for integration

Automate conversions over a simple HTTP API — see the Documentation for endpoints and examples.
