Invoicing and Service Billing Processes
What does this mean for you as our contract partners?

Invoicing and payment processes
With the change to the new SAP system, each contract concluded in 2025 will be assigned a new SAP contract number. You will be informed individually about the contract numbers in 2026.
The previous financial settlement process will be divided into two steps: In future, invoicing will be preceded by what is known as service entry sheet (LERF). The actual invoicing will be based on the LERF checked by GIZ.
Details can be found below in the sections on invoicing that apply to you:
