E-Invoicing Barometer: Modeled XRechnung vs. ZUGFeRD Index
A modeled index of how B2B invoice output splits between pure XML (XRechnung) and hybrid PDF/A-3 (ZUGFeRD / Factur-X) in the run-up to the German issuing mandates. The weekly series is modeled, not a weekly measurement.
Modeled index — not observed weekly data
This barometer is a model, not a measurement. Its weekly series is a fixed baseline published with the model version. This version does not read or blend live telemetry. The values are editorial assumptions, not a representative statistic of the German national market.
Model version: modeled-index-2026.09.3 · Data source: fixed modeled trajectory; no live telemetry
ZUGFeRD 57.7% vs. XRechnung 42.3%
These values come only from a fixed baseline trajectory published with the model version. This version does not read or blend live telemetry.
Modeled Adoption Trajectory
Modeled weekly trajectory across 20 baseline weeks leading into the 2027 and 2028 German issuance mandate milestones. The curve shows the model, not recorded weekly observations.
Citation & Data Syndication
Cite the barometer as a modeled index and name its model version. It is not an observed national statistic.
"The E-Invoicing Barometer from Invoice-Converter.com, a modeled index (model version modeled-index-2026.09.3), puts hybrid ZUGFeRD at 57.7% and pure XRechnung XML at 42.3% for the modeled week 2026-W38. The figures are modeled, not an observed national statistic."
Side-by-Side Format Comparison
Under the German Wachstumschancengesetz, both XRechnung and ZUGFeRD (EN 16931 profile) qualify as structured electronic invoices.
ZUGFeRD / Factur-X
Combines a human-readable visual PDF with structured EN 16931 XML. Enables immediate visual inspection without specialised viewer tools.
- Preserves visual inspection, approval stamps, and PDF archiving
- Broad acceptance across German tax advisors, DATEV, and accounting software
- Practical default standard for commercial SME transactions
XRechnung
Machine-only invoice data stream without visual rendering. Mandatory for public sector procurement (B2G) across federal and state administrations in Germany.
- Mandatory for federal, state, and municipal public buyers (B2G)
- Direct automated routing via OZG-RE and Peppol
- Enables touchless straight-through processing in enterprise ERPs
What the Model Assumes
The model assumes a clear operational division of labor across the German economy: ZUGFeRD carries the majority of overall volume among commercial SMEs, where teams prioritize human readability and seamless integration with existing PDF workflows. That is an editorial assumption of the model, not a measured sample.
The modeled trajectory moves pure XRechnung steadily upward, driven by public procurement requirements (B2G) and mid-market firms upgrading ERP pipelines ahead of the January 2027 issuance deadline. Treat the direction as an expectation, not as a measured trend.
German Mandate Rollout Schedule
Receiving obligation active for all domestic B2B
All domestic businesses in Germany must be equipped to receive structured e-invoices.
Issuing obligation for turnover > EUR 800,000
Businesses above the turnover threshold must issue structured invoices; paper and simple PDFs phase out.
Universal B2B issuing obligation
All transition periods expire; all domestic B2B transactions require structured e-invoices.
Methodology, Model Limits, and Privacy
Every published week is modeled. Weeks 2026-W18 to 2026-W37 come from a fixed baseline trajectory published with the model version, and later weeks repeat its last value. This model version does not read or blend live telemetry. The trajectory is an editorial assumption, not a representative sample or an observed trend in the German national market.
Frequently Asked Questions
Are these measured German market figures?â–¾
No. Every week on this page follows one fixed published model trajectory. This version uses no live telemetry. The series is not a representative survey of Germany.
Can German businesses choose between ZUGFeRD and XRechnung?â–¾
For domestic B2B invoicing, trading partners may agree to use either ZUGFeRD (EN 16931 profile) or XRechnung. When billing German public contracting authorities (B2G), XRechnung is mandatory in most federal and state jurisdictions.
Does ZUGFeRD satisfy the legal German e-invoicing mandate?â–¾
Yes. ZUGFeRD profile EN 16931 (also known as Factur-X) adheres strictly to the European standard EN 16931 and is officially acknowledged by the German Federal Ministry of Finance (BMF) as fully compliant.
How often do the values change?â–¾
The fixed modeled trajectory changes only when a new model version is published. All values stay unchanged between versions; this version reads no live telemetry.
