B2B e-invoicing mandate
Germany
In Germany domestic B2B invoices are issued as electronic documents following the EN 16931 data model, and the obligation to be able to receive them started on 1 January 2025. TecT creates the document in SAP and handles conversion and delivery in the integration layer.
Supported processes
Outgoing e-invoice
The document is produced in a format compliant with the EN 16931 data model and delivered to the buyer's channel.
Incoming e-invoice
The received document is validated and written into SAP; missing fields reach the user with the reason.
Archive and audit trail
Sent and received documents are stored together with their status history.
Integration path
The document is created inside SAP. Country-specific rules are applied outside SAP, in the TecT BTP Bridge layer; from there the document is sent to the buyer's electronic channel and the result is written back to the record in SAP.
Clean Core is preserved: no local add-on is installed in the SAP core, and when the regulation changes the update is made in the integration layer. The same structure works from SAP R/3 through to Public Cloud.
