Is XRechnung mandatory for all German businesses?

For B2G (government): Yes, already mandatory. For B2B: Not yet, but receiving e-invoices becomes mandatory January 2025, and sending phases in 2027-2028.

What's the difference between XRechnung and ZUGFeRD?

XRechnung is pure XML (no visual component). ZUGFeRD is a hybrid PDF with embedded XML. Both are EN 16931-compliant. ZUGFeRD with XRechnung profile satisfies government requirements. Compare XRechnung vs ZUGFeRD

What is a Leitweg-ID?

The Leitweg-ID is a routing identifier that directs invoices to the correct German government department. Format: 04011-xxxxx-xx. Required for all B2G invoices.

Can I view XRechnung files?

XRechnung is pure XML and needs a viewer to display in human-readable format. You can use online XRechnung viewers or our validator which shows invoice details.

Which syntax should I use—UBL or CII?

Most implementations use UBL because it's the Peppol standard. CII is compatible with ZUGFeRD/Factur-X. Both are equally valid for XRechnung.

XRechnung Explained: Germany's E-Invoice Standard (2026)

How XRechnung Works

XRechnung defines a strict XML structure based on the European standard EN 16931. It supports two syntaxes:

UBL 2.1 (Universal Business Language) — Most common, used by Peppol
UN/CEFACT CII (Cross-Industry Invoice) — Used by ZUGFeRD/Factur-X

German-Specific Rules

XRechnung adds 21 business rules beyond EN 16931, including:

Leitweg-ID: Required routing identifier for German government invoices
Payment terms: Specific format requirements
VAT categories: Mapping to German tax codes

Submission Methods

XRechnung invoices can be submitted via:

ZRE (Zentrale Rechnungseingangsplattform): Federal government portal
OZG-RE: State government portals
Peppol: Via certified Access Point
Email: To specific submission addresses (varies by authority)

Why XRechnung Matters

B2G: Already Mandatory

Since November 2020, all invoices to German federal authorities must be XRechnung-compliant. Most state governments have similar requirements. Non-compliant invoices may be rejected.

B2B: Coming 2025-2028

Germany's B2B e-invoicing mandate phases in:

January 2025: All businesses must receive EN 16931 invoices
January 2027: Businesses >€800K must send e-invoices
January 2028: All businesses must send e-invoices

XRechnung or ZUGFeRD are both accepted for the B2B mandate.

Invoice Navigator supports all XRechnung versions and automatically validates against the latest KoSIT rule set, catching format-specific errors that generic validators miss.

How to Get Started

Step 1: Check Your Requirements

Are you invoicing government (B2G) or only businesses (B2B)? Government requires XRechnung; B2B can use XRechnung or ZUGFeRD.

Step 2: Get Your Leitweg-ID

For government invoices, you need the recipient's Leitweg-ID routing number. This is usually provided on purchase orders or contracts.

Step 3: Generate or Convert

Use your accounting software's XRechnung export, or convert existing invoices using our generator.
