Joint digital procurement means that BKW and suppliers use the same platform for their procurement processes.
BKW is now handling its procurement processes via the Ariba Network platform. Accordingly, our suppliers have to use Ariba Network. In future, our procurement operations will be exclusively digital and rely on simple, electronic and swift cooperation.

All BKW suppliers will receive an invitation from Group Procurement to register on Ariba Network.

Ariba makes a distinction between two different user accounts. Suppliers choose the one that best suits their needs – and are more than welcome to do so in consultation and coordination with their contacts in BKW Purchasing.
We assume that some of our suppliers will require a paid enterprise account. In detail, the differences between the user accounts are as follows:

Standardaccount (free)


Access to basic network functions, such as order management and invoice generation. You also have access via the emails sent by BKW or Ariba.

Enterprise account (subject to a charge)

In addition to the basic features, this account offers advanced features, such as a search function for orders and invoices, document archiving, reporting, publication of buyer-specific catalogues, connection to your logistics and accounting system, or a support centre.

The costs involved in registering for an enterprise account are listed here.

Once a supplier has registered, they’ll be connected to Ariba Network. This is followed by a validation and testing phase before the account goes live. This process takes between six and 22 weeks, depending on the level of integration on Ariba Network.



BKW uses a variety of buying channels on Ariba Network. Together with our suppliers, we work out the appropriate solution for the products and services offered. BKW Group Procurement contacts suppliers as soon as the company is scheduled to cooperate on Ariba Network.



Experience shows that it takes up to six weeks to create/connect a catalogue that BKW or the supplier maintains on Ariba. Meanwhile, it takes up to 12 weeks to create a punchout catalogue, where the buyer is directed to the supplier’s external online shop. The duration depends on whether catalogues already exist or whether they need to be created from scratch.



  1. Create the catalogue: BKW makes contact and provides training; the supplier creates the catalogue.
  2. Upload for testing purposes: upload the catalogue to an Ariba Network test account.
  3. Troubleshooting: test access and perform any necessary troubleshooting operations.
  4. Testing by BKW: the catalogue is validated and tested.
  5. Upload to Ariba Network: the catalogue is available; digital procurement can begin.
