Technical prerequisites

In terms of software, the Supplier Portal does not make great demands on your company.

All you need to gain access is an Internet connection and a web browser. The Supplier Portal is optimised and supports Microsoft Internet Explorer (Version 5.0 and higher) and the latest Mozilla/Firefox browser.

We recommend that you always use the latest version of your browser and regularly import the updates provided by your browser manufacturer. Older versions sometimes have security vulnerabilities which have been eliminated in the newer browsers.


To ensure secure communication between you and the REWE Group, we use a permanent 128 Bit SSL encryption for data communication in the Supplier Portal. Consequently the security and integrity of the data and the communications are guaranteed at all times.
