Invoicing and Service Billing Processes
As part of its digital transformation, GIZ switched to the new SAP S/4HANA system worldwide on 1st January 2026. This step is intended to standardize business processes, harmonize GIZ’s IT landscape worldwide and integrate GIZ headquarters and country offices more closely, thereby increasing efficiency.
What does this mean for you as our contract partners?
Bidding submissions
In the department of bidding submission and in the process of contract awarding and drawing up, nothing will initially change for you as a result of the SAP changeover.
The tender submission will continue via our functional electronic mailbox: TH_Quotation@giz.de or by sending documents to the following address:
GIZ Office Bangkok
193/63 Lake Rajada Office Complex, 16th Fl.
New Ratchadapisek Rd,

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:
