SAP Ariba

The K+S Group is consistently pursuing the goal of driving digitalization. Therefore, we decided to implement SAP Ariba Buying in addition to SAP Ariba Sourcing. The aim is to make procurement processes easier and more efficient with the innovative SAP Ariba solutions and the Ariba network and to further increase collaboration with our suppliers.  

SAP Ariba Sourcing and Ariba Buying at K+S

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 K+S or have at least applied. The Ariba Buying is used as a convenient procurement solution for indirect purchasing. As a supplier, you have the possibility to publish catalogues or online shops with your products in the K+S procurement system.

What is the Ariba Network?

The Ariba Network is one of the largest business networks in the world and is a dynamic and digital marketplace. When registering in the Ariba Network, you gain access to a business network of millions of companies. It supports in efficiently expanding your existing customer relationships, identifying business opportunities as well as acquiring future/new customers.

What are the advantages for you as a supplier?

  • You have the opportunity to publish catalogues with your products in the procurement system of K+S. 
  • You can participate in K+S tenders and bids. 
  • Through increased transparency you can continuously check the entire ordering process and the current status of your tenders. 
  • You will find all tenders and auctions to which K+S has invited you, including the relevant documents, on one platform. 
  • You can communicate with the responsible purchaser directly via Ariba, so that the communication can also be tracked at any time.
  •  There are decreased process and administration costs due to automation and digitalization.
  • The participation in tenders and bids via Ariba Sourcing is free of charge for you. 
  • You can present your company in the Ariba network and get in touch with potential new customers (regional and national). 

How do you use the Ariba network?

Registration is required prior to use the Ariba Network. You have to choose between two account types, which are: Standard Account or Enterprise Account. Which account is right for you depends on the scope of your overall business relationship. If you would like to provide K+S with a catalogue or online shop, you need an Enterprise Account. Suppliers who participate in K+S tenders and bids exclusively via SAP Ariba Sourcing, only require the Standard Account. If you already have an account on the Ariba network, you can log in with your existing access data and connect to our K+S account.
