- From 2025: Businesses must be able to receive B2B e-invoices from domestic partners.
- From 2027: Companies with an annual turnover of more than 800,000 Euros must be able to send B2B e-invoices.

Supported Formats.
Formats that are supported for validation, receiving invoices (inbound), and sending invoices (outbound):

Hybrid format that combines XML and PDF. Machine and human-readable (read-only copy). - XRechnung 3.02 (UBL / CII):
Only machine-readable, XML-based. Does not include a read-only copy. - Peppol BIS Billing 3.0 (UBL)
How It Works.
Receiving Invoices (Inbound).
Once the e-invoice is received, the data is validated against the underlying regulations and standards according to EN16931. Different E-Invoice formats are automatically detected. In addition, the e-invoices are validated against the latest versions of the official national regulations. After the e-invoice is successfully validated, a readable copy of the transmitted invoice is generated in a standardised layout as PDF/A-3. A readable copy of a ZUGFeRD invoice is also generated.
Sending Invoices (Outbound).
The source format of the customer’s invoice data is converted into the requested e-invoice format for Germany. If the ZUGFeRD e-invoice format is chosen, a readable PDF with the CII format is generated per e-invoice. If the Peppol communication channel is chosen, the Peppol BIS Billing V3 format is selected as standard.
