Which ZUGFeRD version do you generate?
We generate ZUGFeRD 2.5 / Factur-X 1.09. The latest published specification is ZUGFeRD 2.5.2 / Factur-X 1.09.2 of 4 August 2026. For recognition as an e-invoice, the BMF accepts ZUGFeRD from version 2.0.1 with XML that meets EN 16931.
Which profile do you generate, and is MINIMUM a valid e-invoice?
The default is EN 16931. Select EXTENDED before upload if the invoice must carry a delivery-note reference. MINIMUM and BASIC WL do not count as e-invoices because they lack mandatory invoice data; we do not generate them.
Can recipients read ZUGFeRD without special software?
Yes. Any PDF reader shows the invoice. Accounting software also reads the embedded XML and imports the data without retyping.
Do you send the invoice for me?
No. We create and validate the file; sending it is up to you, for example by email. ZUGFeRD does not replace a sending channel.
What is the difference between Factur-X and ZUGFeRD?
Technically none: ZUGFeRD 2.5 / Factur-X 1.09 describe the same format with the same profiles from MINIMUM to EXTENDED. ZUGFeRD is the German name and adds the XRECHNUNG profile; Factur-X is the French name.
Do I need a subscription?
No, a subscription is optional: you can pay for each conversion on its own. The first subscription includes a free 3-day trial. You pay only when you download. If a paid single conversion fails because of a technical error that our support cannot fix, we refund it on request (money-back guarantee).
What happens if data is read incorrectly?
You check and correct every recognised field before you pay. Validation errors and missing data that the profile requires block the valid hybrid PDF. We refund only on request and only when the conversion fails because of a technical error that our support cannot fix; you make content corrections in the review step.
Do I have to issue e-invoices as a small business (Kleinunternehmer)?
No. Small businesses under § 19 UStG (Kleinunternehmer) are exempt from the German issuing duty, but they must be able to receive e-invoices. If a customer still asks for an e-invoice, you can create it here.
