Supplier Portals

We use two portals to communicate with our suppliers and other external partners. There is a difference in the security level of the data and documents stored on these platforms.

The SupplierPortal is used for general communication with suppliers and maintaining supplier informations. In the future, you will get further information and applications in purchasing (e.g. quotation), quality and logistics.

On the Collaboration Portal we exchange confidential documents and data with our suppliers. Additionally we provide logistics applications here for selected suppliers.

The portals are linked to each other and will be combined in the future.


Login to the SupplierPortal here. Please use this login, if you have applied to be a supplier or you have been invited to register in this portal.
