NiSource has implemented SAP Ariba for our suppliers to receive purchase orders and submit invoices electronically. If your company currently provides products or services to NiSource, please follow the instructions below to enable electronic transacting.

Benefits to Suppliers:

• Supplier self-service for items such as registration, updating company information and managing orders and payments
• Real-time Purchase Order delivery, which speeds the time to get the order to the supplier
• Invoice automation that reduces potential errors and labor costs for suppliers to invoice NiSource
• Improved invoice tracking
• Timely, predictable payments

Before Submitting a Request

Please check internally with your accounting department to determine if the company ALREADY uses Ariba to process documents with NiSource & Affiliates or other customers.  

If YES, the portal administrator will need to receive the initial registration request to link the correct portal with the NiSource profile.  (other users can be authorized once the correct portal has been linked)

If NO, a sales representative CAN create the portal and complete the 1st stage of profile creation; HOWEVER, this person becomes the "administrator" of the portal.  To complete onboarding, the transactional questionnaire will need to be completed to create the accounting profile. (Sometimes companies prefer a specific team or person be the administrator and delegate permission to authorized users based on roles, please review portal design internally.)
