Services and construction work

GIZ is a public contracting authority within the meaning of the German Act against Restraints on Competition (GWB). For contracts above the EU thresholds, we are required to comply with the following regulations:

• German Act against Restraints on Competition (GWB)
• German Ordinance on the Award of Public Contracts (VgV)
• Part A of the German Construction Contract Procedures (VOB/A) 

This applies not only to the public-benefit business area but also to GIZ self-initiated measures and projects implemented by International Services.

For German Government commissions below the EU thresholds, we are obligated to comply with the relevant provisions of the following regulations:

• Regulation on Sub-threshold Procurement (UVgO) for the procurement of materials and equipment
• VOB/A for construction work with certain simplifications

All contracts for services and construction work are subject to the respective regulations and documents, including annexes, that are published or made available with the tender documents as part of the tendering process. 

If questions arise during the course of contract implementation concerning the contract documents, please get in touch with the Procurement and Contracting Division contact listed in the tender or contract documents.

Your invoice can be processed faster and more effectively if you use the settlement forms provided by GIZ. Please note: 

• The settlement requirements
• The invoicing requirements
• The guide to completing the settlement forms 

Please get in touch with the contact person responsible for your contract if you have questions about settlements and repayments. You will normally find their contact details on the cover page of your contract. 

Invoice submission

We will accept invoices submitted in 2025 in XRechnung format or other format compliant with the CEN standard (EN 16931-1) in the current version and in PDF format. 
Please send your invoice by email to @email or submit it via the PEPPOL network (GIZ’s buyer reference ID: 993-80072-52). 

Please note: 
From 2026 onwards, you will no longer be able to submit invoices via the PEPPOL network. 

XRechnung invoices will then only be able to be submitted by email. 

When submitting an invoice, please state the GIZ order/contract number in the subject line of the email and ensure that all the relevant information is clearly visible on the invoice, including:

•    Purchase order number 
•    GIZ contract/order number 
•    Service delivery period

In 2026, due to a large-scale system migration, new processes will be introduced for service contract invoices and there will be new channels for the receipt of all invoices in PDF and XRechnung format. We will be sending you more details on this before the end of the year.
