FAQ about e-invoicing

Answers about XRechnung, ZUGFeRD, and Leitweg-ID.

What's the difference between XRechnung and ZUGFeRD?

expand_more
XRechnung is a pure XML file, mandatory for invoices to German government bodies. ZUGFeRD 2.3 is a PDF file with embedded XML – ideal for business customers because it can be processed automatically AND read by humans.

Do I need a Leitweg-ID?

expand_more
For invoices to German public buyers, yes. The ID is stored on the customer and automatically used in XRechnung. For business customers it is optional.

Does this work for small businesses?

expand_more
Yes. With the small-business rule enabled, VAT rates > 0 are rejected. The country-specific note (e.g. "According to § 19 UStG no VAT is charged.") is auto-embedded in PDF and XML.

Is the invoice validated?

expand_more
Yes, the built-in check validates the XML format and business rules of the EN 16931 standard. You see the result directly in the app – before and after sending.

Can I generate a test invoice?

expand_more
Yes. In the e-invoicing company settings you can generate a test XML in one click and run it against the validator.
