ZUGFeRD Invoice Generator (PDF + Embedded XML)

ZUGFeRD is the German hybrid e-invoice format: a readable PDF for humans and an embedded XML file for machines. It’s widely used for B2B billing and aligns with EN 16931 requirements. This page lets you create a ZUGFeRD invoice online and download it instantly.

Who is this for?

Finance teams, freelancers, and SaaS platforms that need a compliant invoice format for Germany. If you want one file that works for recipients and for automated processing, ZUGFeRD is a practical choice.

The generator focuses on hybrid invoices: PDF/A-3 + embedded XML (UN/CEFACT CII). You keep a human-friendly PDF while enabling structured, machine-readable accounting.

What you get

  • • ZUGFeRD PDF/A-3 invoice with embedded XML
  • • EN 16931-aligned structured data (CII)
  • • No account required for one-off invoices
  • • Stateless processing (no long-term storage)

ZUGFeRD vs XRechnung

If you need a PDF that humans can open and approve, choose ZUGFeRD. If you need an XML-only format for specific public-sector workflows, XRechnung may be required. InvoiceXML supports both approaches via API.
