Electronic invoices must be sent in accordance with the e-Invoice Regulation (E-Rech-V) via an administrative portal as defined by the Online Access Act (OZG). The law obliges the Federal and state governments to offer their administrative services electronically via administrative portals and to link them to one another to form a portal network. The Federal Government has provided the OZG-compliant invoice submission portal (OZG-RE) for this purpose.
According to the German Federal Government’s E-Rech-V, KfW is obliged to receive invoices electronically that are used to invoice a delivery or other service if they meet the legal requirements for electronic invoices.
It is important that, as the invoicing party, as of 27 November 2020 you send your invoices to the official contracting authorities in electronic form.
In Germany, the XRechnung data exchange standard should always be used. This is based on the EU standard CEN 16931, which defines a uniform technical standard for electronic invoicing. The core of the standard is a data model that describes and standardises the content and structure of electronic invoices.
The German applies to all invoices in the Federal Government’s official procurement that are used to invoice a delivery or other service and that were issued after the fulfilment of official contracts, contracts and concessions.
The obligation to issue invoices electronically does not apply to invoices that are issued up to an amount of €1,000.00 after the fulfilment of a direct order, which are subject to confidentiality, which concern matters of the German Federal Foreign Office and other types of procurement abroad, which are to be issued by way of an official delegation of powers in accordance with Section 159(1)(5) of the Economic Competition Act.
The Route ID must be specified for e-invoices and works like an address. KfW invoices can be allocated using the Route ID. You must provide the Route ID, as communicated by us, in unchanged form on electronic invoices.
You will receive the Route ID from KfW together with the order.
No, invoicing is electronic and you may only submit an invoice once.
No, digitally signed PDF invoices do not comply with the XRechnung data exchange standard and are therefore not electronic invoices that KfW can accept.
The issuing, transmission and receipt of electronic invoices must be carried out in a structured data format. The XRechnung data format supports automatic and electronic processing.
If you need to correct an invoice, you can also send us the correction via the OZG-RE portal. To do this, enter the Route ID previously used in the invoice in the corrected invoice.
In this case, please get in touch with your respective procurement contact person at KfW.
You can submit credit notes for e-invoices electronically via the OZG-RE portal. The credit note must clearly indicate which invoice is to be amended. Also enter the same Route ID as for the invoice.
You can send reminders for electronic invoices to KfW as follows:
- • by email to your contact person at KfW
- • or by post to your contact person at KfW
As before, you will need to issue reminders for e-invoices in writing to the purchaser at KfW.
The statutory retention obligations also apply to electronic invoices. As a service provider, you must retain these under your own responsibility.
There are no special IT requirements to be observed for electronic invoicing.
The OZG-RE portal has web-based input screens for creating e-invoices in the XRechnung format or you can use special software for e-invoicing.

An XML (eXtensible Markup Language) file presents data in a structured form in a file that can be read by both humans and machines. Data transfer often takes place with XML files. The XRechnung data exchange standard also uses XML.
The validation module is publicly available to you and checks electronic invoices according to defined rules.
As a service provider, you can use the validation module and the reference implementation to review your e-invoices.
With electronic invoice processing, you can save paper and postage costs in the future. The effort required for manual invoice processing can also be reduced by using e-invoices.
