An Assistant That Does the Work for You

Stay compliant, skip the hassle

Forget filling out forms. Just say what you need in plain words and the assistant takes care of ZUGFeRD compliance, XRechnung and EN 16931 included.

Just Describe What You Need

Skip the menus and the data entry. Give the assistant an instruction ("turn this PDF into ZUGFeRD" or "check this XML") and it runs.

XML

Works With PDF & XML

Attach any PDF or XML invoice. The assistant reads it, understands the data, and returns a compliant file you can download in the chat.

EN

EN 16931 Compliant

Whatever the assistant generates matches the European EN 16931 standard and the ZUGFeRD PDF/A-3 specification, ready for XRechnung, Peppol BIS and the German B2B e-invoicing mandate.

Private by Design

Your files are processed in-memory and never stored on our servers. They are purged the moment your request is complete - fully GDPR compliant.

PDF → ZUGFeRD

Let your PDFs become compliant e-invoices on their own.

Stop retyping supplier invoices. The assistant scans your PDF, works out its layout and hands back a validated ZUGFeRD file that satisfies XRechnung and the German e-invoicing mandate.

  • OCR and AI read it for you
