In Germany, e-invoices have long since become more than just a digitalization issue—they are increasingly mandated by regulation. Two terms come up particularly often in this context: ZUGFeRD and XRechnung.
Many companies are therefore asking themselves: ZUGFeRD or XRechnung—which format is the right one, and when?
In this post, we explain:
ZUGFeRD (Central User Guide of the German Electronic Invoicing Forum) is a hybrid invoice format.
It combines:
ZUGFeRD is primarily used in the B2B sector, as it enhances existing PDF-based invoicing processes without completely replacing them. For certain profiles, ZUGFeRD also complies with the European standard EN 16931.
Typical applications of ZUGFeRD:
XRechnung is a pure, structured XML format for electronic invoices.
Unlike ZUGFeRD, an XRechnung does not include a visual representation, but consists solely of machine-readable invoice data.
XRechnung was developed specifically for the exchange of invoices with public sector clients and is mandatory in many cases in Germany.

Typical applications of XRechnung:
A comparison of ZUGFeRD and XRechnung shows that while both formats comply with the same European standard, they are designed for different purposes.
One often underestimated difference between ZUGFeRD and XRechnung is the file size.
In practice, this difference is particularly relevant in the following cases:
For the public sector and highly automated processes, XRechnung is therefore often more technically efficient, while ZUGFeRD excels in the B2B environment, where readability is a key priority.
There is no one-size-fits-all answer to the question “XRechnung or ZUGFeRD?”; it depends on the specific context:
It is important to note that the recipient decides which format is accepted.
Regardless of whether ZUGFeRD or XRechnung is used, companies face similar challenges:
Many companies therefore rely on standardized, automated e-invoicing solutions that cover both scenarios.
Anyone who wants to set up future-proof e-invoices should take a holistic view of formats and transmission channels—rather than making decisions in isolation.
