Every PDF Billino generates is a valid Factur-X 1.0 / ZUGFeRD 2.x document at the EN 16931 (Comfort) profile — the full standard, not a stripped-down subset. Here's exactly what that means and how to verify it.
ZUGFeRD (Germany) and Factur-X (France/EU) are the same technical format under different names. Both embed a machine-readable XML invoice inside a PDF/A-3 file — the PDF looks like a normal invoice to the human eye, but accounting software and tax authorities can extract and process the data automatically without any manual entry.
The format is built on the UN/CEFACT Cross Industry Invoice (CII) schema and the European core standard EN 16931:2017. It is accepted by every major German and European accounting system — DATEV, Lexware, sevDesk, FastBill, and all e-invoicing platforms mandated by the EU.
ZUGFeRD defines several profiles, each carrying a different amount of data. Billino uses the EN 16931 profile — known as "Comfort" in ZUGFeRD terminology. This is the most complete interoperability level short of the extended (XRechnung) profile required for invoicing German public authorities.
| Profile | ZUGFeRD name | Line-level tax | Payment terms | Addresses | Billino |
|---|---|---|---|---|---|
| MINIMUM | Minimum | — | — | — | — |
| BASIC WL | Basic WL | — | Header only | Partial | — |
| BASIC | Basic | Partial | Header only | Partial | — |
| EN 16931 | Comfort | Full ✓ | Full ✓ | Full ✓ | Used |
| EXTENDED | Extended / XRechnung | Full ✓ | Full ✓ | Full ✓ | — |
The EN 16931 profile is required for invoicing B2B customers who process invoices in DATEV or similar systems, and is the level most commonly required by medium-sized businesses. XRechnung (EXTENDED) adds fields only required when invoicing German government bodies — Billino is aimed at freelancers and small businesses, so EN 16931 / Comfort is the right fit.
Every Billino PDF embeds an XML block covering:
