Can I use Factur-X for German government invoicing?

Yes — if you use the XRechnung profile. Factur-X with XRechnung profile produces a PDF/A-3 file with CII XML that passes all BR-DE-* validation rules. German government portals accept this.

Which format is better for cross-border invoicing?

Factur-X — it works in France, Germany, and any EN 16931-compatible country. XRechnung is Germany-specific. For pan-European coverage via Peppol, consider Peppol BIS 3.0 (UBL) as a third option.

Can one file be both Factur-X and XRechnung?

Yes. A Factur-X file using the XRechnung profile is simultaneously a valid Factur-X invoice and an XRechnung-compliant invoice. The PDF/A-3 container doesn’t affect the XML validity.

Which ERPs support each format?

Most German ERPs (SAP, DATEV, Lexware) support both. SAP has native XRechnung export and ZUGFeRD/Factur-X generation. DATEV supports ZUGFeRD natively. Check our ERP integration guides for specific configurations.

Factur-X vs XRechnung: Which Format for Germany and France?

Side-by-Side Comparison

Feature	Factur-X	XRechnung
File format	PDF/A-3 with embedded CII XML	Pure XML (UBL 2.1 or CII D16B)
Human readable	Yes — opens as a normal PDF	No — requires a viewer or renderer
XML syntax	CII D16B only	UBL 2.1 or CII D16B
Profile system	6 profiles (Minimum through XRechnung)	Single specification with versioning
EN 16931 compliant	Yes (EN 16931 profile and above)	Yes
Country coverage	France + Germany + cross-border EU	Germany only
German B2G accepted	Yes (with XRechnung profile)	Yes (primary format)
German B2B accepted	Yes (EN 16931+ profiles)	Yes
Peppol delivery	Possible via CII syntax	Standard (UBL via Peppol BIS)
File size	Larger — includes PDF rendering + fonts	Smaller — pure structured data
Archival	PDF/A-3 compliant by design	Requires separate archival strategy

Factur-X

Factur-X (identical to ZUGFeRD 2.x) is a hybrid e-invoice format. It embeds a structured CII D16B XML file (factur-x.xml) inside a PDF/A-3 document. Open it in Adobe Reader — you see a normal invoice. Feed it to an ERP — the XML gets extracted and processed automatically.

Factur-X defines six profiles: Minimum, Basic WL, Basic, EN 16931, Extended, and XRechnung. For EU mandate compliance, use EN 16931 or higher. The format is maintained jointly by the Franco-German FNFE-MPE consortium.

XRechnung

XRechnung is Germany’s national CIUS of EN 16931. It’s pure XML — no PDF, no visual representation, no embedded fonts. The file is structured data only, designed for machine-to-machine processing.

XRechnung supports both UBL 2.1 and CII syntaxes. It adds 26 German-specific rules (BR-DE-01 through BR-DE-26) including Leitweg-ID requirements for government invoicing, mandatory seller contact details, and specific payment means codes. Maintained by KoSIT.

Key Differences Explained

Hybrid vs. pure XML

Factur-X gives you a human-readable PDF plus machine-readable XML in one file. XRechnung gives you pure structured data. If your recipients still need PDFs for approval workflows or archival, Factur-X is the practical choice. If everything is automated, XRechnung is leaner.

Cross-border vs. Germany-only

Factur-X covers France and Germany (and any EN 16931-compatible country). XRechnung is Germany-specific. If you serve both French and German customers, one Factur-X implementation handles both markets. XRechnung only covers Germany.

XML syntax

Factur-X uses CII exclusively. XRechnung supports both UBL and CII. Since Peppol defaults to UBL, most XRechnung implementations use UBL for network compatibility. If you’re building CII-first (for Factur-X/ZUGFeRD), be aware that Peppol delivery typically expects UBL.

When to Use Factur-X

·Recipients need a visual PDF for human review or approval
·You invoice in both France and Germany
·Your archival workflow requires PDF/A-3 documents
·You’re transitioning from PDF-based workflows and need a bridge format

When to Use XRechnung

·Invoicing German government via Peppol (XRechnung is the standard)
·Pure machine-to-machine B2B where no human reads the invoice
·File size and processing speed are priorities
·You’re already on UBL/Peppol and don’t need a PDF layer

Can You Use Both?

Yes. Factur-X with the XRechnung profile gives you a PDF wrapper with XRechnung-compliant CII XML inside. The PDF provides human readability; the XML meets German CIUS rules. This is accepted by German government portals that require XRechnung. You get both visual representation and full compliance in one file.
