The formats of the e-invoice
Two formats have been established for electronic invoice exchange: XRechnung and ZUGFeRD. Both comply with the EU standard EN 16931 and enable automatic, seamless processing.
XRechnung
- Pure XML format with the extension .xml
- Is already established in invoicing with authorities (B2G)
- Supports UBL and CII as XML syntax
ZUGFeRD
- Hybrid format: combination of PDF/A-3 and embedded XML file
- File extension .pdf, XML attachment: zugferd-invoice.xml
- Primarily intended for business-to-business exchanges (B2B)
- Uses only the CII standard
While XRechnung is mandatory for public contracting authorities in Germany, the use of ZUGFeRD remains voluntary in the B2B sector. Nevertheless, both formats are legally recognized and meet the legal requirements of the E-Invoicing Regulation.
How must electronic invoices be archived?
Electronic invoices must be processed and archived digitally—a paper printout is not sufficient. Since formats such as XRechnung and ZUGFeRD are legally equivalent to paper invoices, they are subject to a ten-year retention period.
With SAP Business One, documents can be exported directly to SharePoint. If SharePoint is configured as an audit-proof repository, it meets all compliance requirements. Since the necessary licenses are usually already included in Microsoft 365, there are generally no additional costs – a particularly cost-effective solution.
This is how you ensure that your company complies with legal requirements while also operating efficiently.
