E-invoicing mandate — Stella generates both formats automatically.
ZUGFeRD PDF/A-3 with embedded XML for classic recipients or pure XRechnung XML for public authorities. Both formats are generated automatically from every order - without switching tools.
- ZUGFeRD 2.x (PDF/A-3 with embedded XML)
- XRechnung (pure XML for public authorities)
- Mandatory receipt in B2B already in force
- Automatic validation before sending
What applies to e-invoicing?
With the Growth Opportunities Act (Wachstumschancengesetz), structured electronic invoices become mandatory in the B2B sector. There are transition periods for sending, but the obligation to receive already applies.
- Since 2025: companies must be able to receive e-invoices
- Stella handles both: receiving and sending
- GoBD-compliant retention for 10 years including XML validation
- Transition period: PDF with embedded XML still permitted
ZUGFeRD — PDF/A-3 with embedded XML
A classic PDF invoice with an embedded XML data record. People read the PDF, the software reads the XML. Compatible with the common accounting programs such as DATEV, Lexware, or sevDesk.
- EN 16931 profile, extended profile on request
- XML in the PDF/A-3 attachment, embedded per the standard
- PDF visually identical to the classic invoice (logo, IBAN, layout)
- Automatic validation before sending
XRechnung — pure XML for public authorities
Mandatory for public-sector clients (federal, state, municipal): pure XML without a PDF. Stella generates the XML automatically from the order - you don't have to fill in the many required fields by hand.
- XRechnung schema (UN/CEFACT Cross Industry Invoice)
- Validation before sending against the schema and requirements
- Sending by email or optionally via the Peppol network
- Format accepted by federal, state, and local authorities
Incoming e-invoices prepared automatically
When a supplier invoice arrives as a ZUGFeRD PDF, Stella detects the XML, reads out the fields, and suggests a posting in the open-items list. You review, approve - done.
- Automatically detects embedded XML in incoming PDFs
- Field mapping: supplier, document number, VAT, gross total, due date
- Posting suggestion for you to approve - no posting without confirmation
- The original XML is archived unchanged (GoBD)
10 years of retention including validation
Every e-invoice is archived both as a PDF and as a separate XML file. The audit log shows who created what and when. A checksum chain prevents subsequent manipulation.
- Original PDF and extracted XML stored separately in the archive
- Checksum per file in a tamper-proof audit log
- Re-validation possible at any time
- Export package for the tax audit: all receipts with a checklist
