What are ZUGFeRD and Factur-X?
ZUGFeRD and Factur-X describe a hybrid invoice format. You receive a PDF file that also contains a structured XML invoice. The visible PDF helps humans read the invoice, while the embedded XML is intended for structured processing and automation. Factur-X is essentially the French label for the same technical approach.
Why is the PDF alone not enough?
The PDF only gives you the visual representation. For validation, follow-up processing or integration with other systems, the structured data matters. The viewer extracts those invoice fields and turns them into a clear invoice view you can actually work with.
How to open ZUGFeRD or Factur-X
- Open the free viewer.
- Drag the PDF into the browser or pick it from your device.
- The viewer detects the embedded XML and displays the invoice in a readable layout.
What the viewer handles for you
- Automatic format detection.
- Extraction of the structured data from the PDF document.
- Readable rendering of line items, totals and partner information.
- Technical details and validation support when you need more than the visible PDF.
Privacy and intended use
Processing stays local in your browser session. Neither the PDF nor the XML data is uploaded to our servers or stored there. The viewer is ideal when you need to understand, review or share individual ZUGFeRD or Factur-X invoices quickly.
When hybrid invoices turn into a recurring workflow
Once those files arrive every day, viewing and printing are only the first step. Then you need allocation, checks, approvals and posting. That is where the next level starts: automated e-invoice workflows around SAP Business One.
