Sourcing platform

K+S conducts tenders and bids using the SAP Ariba sourcing platform. In principle, we only invite companies that have already qualified as suppliers for the K+S Group or have at least applied. You will receive invitations to tender and bids by e-mail only.

If you have not yet registered for K+S in the Ariba Network, you will receive a second e-mail with the invitation to tender inviting you to register in the Ariba Network and establish a business relationship with K+S via the network. Please use the link in the registration request to register once in the Ariba Network or to link your existing Ariba Network account to the K+S account. The registration is completed after a few steps. All you have to do is fill in the mandatory fields in your supplier profile.

If you already have an active business relationship with K+S via the Ariba network (e.g. by participating in past tenders of the K+S Group using Ariba), please click on the link to the tender in the invitation. Please register with your existing data, a new registration is not necessary.

For more information on SAP Ariba for Suppliers, please visit the Ariba website. Participation in K+S tenders and auctions is free of charge (i.e. the transaction costs stated on the SAP Ariba page do not apply to participation in tenders and bids).

Your advantages as a supplier when using the sourcing platform:

  • You will find all tenders and bids to which you have been invited by K+S, including the relevant documents, on one platform.
  • You can view the current status of your tenders at any time.
  • You can communicate directly with the responsible buyer using Ariba, so that the communication can also be traced at any time.
  • Participation in tenders and auctions for K+S via Ariba Sourcing is free of charge for you as a supplier.
  • With your Ariba Sourcing access, you can be invited to tenders and bids from other customers, provided they also use the platform.
  • You can present your company in the Ariba network and make contact with potential new customers (regional and supra-regional).
