Welcome to the
Norfolk Southern Corporation 
Supplier Information Portal


Welcome to the Norfolk Southern Corporation Supplier Information Portal. This portal provides information for all suppliers conducting business with Norfolk Southern on Ariba Network. For your organization, this means that the traditional way of transacting with us is changing fundamentally. On this site you will find information regarding the transformation as well as a number of tools to help answer any of the questions you may have.


Norfolk Southern's Ariba Network Initiative

Overview of Ariba Process:

  1. NS sends Purchase Order to vendor via email from Ariba Network.
  2. Vendor clicks Process Order button in email, then creates a new Ariba Network account or connects with an existing account.  
  3. Vendor sends Order Confirmation to NS – this is optional.
  4. Vendor sends Ship Notice to NS – this is optional. 
  5. Vendor sends Invoice to NS – this must be sent through Ariba portal.  Please do not mail or email invoices to NS.
  6. NS enters Goods Receipts as items are delivered.
  7. NS sends payment when Invoice Reconciliation is complete.  This process checks that the invoice price matches the purchase order price and will pay out the invoice up to the quantity of goods received.
