What is the ARIBA Network?

The University has transitioned from its legacy purchasing system to the ARIBA eCommerce platform for its procurement transactions. The University will contact its UW-Registered suppliers and provide instructions on how to enroll in the Ariba Network.

Important: This is a separate process from the Supplier Registration Form and Electronic Payment Registration.

Registering for the ARIBA Network will allow you to:

  • Receive purchase orders electronically from the University
  • Create and transmit invoices electronically to the University
  • Leverage the full suite of UW buying options, including Blanket Purchase Orders (BPOs)
  • Expand business opportunities through exposure to other potential customers using the ARIBA Network

There is no commitment or guaranteed business as a result of becoming a registered ARIBA or University supplier.

What Departments Need to Know

When a supplier joins the ARIBA Network, their transactions in ARIBA will change from a manual ordering and invoicing process to an electronic process with less resources needed to place orders and reconcile invoices. The University takes the extra measure of communicating with newly enabled suppliers with a Welcome email.

How To Check If a Supplier is Part of the ARIBA Network

Review your preferred supplier on the Supplier Search report (B.I. Portal). and check the "Order From" address type. If the ARIBA Network column shows "Y" (Yes), then the supplier is part of the ARIBA Network.

How To Get Your Preferred Supplier Invited to Join the ARIBA Network

Procurement Services will send the email invitation to join the ARIBA Network, called the Trading Relationship Request (TRR), to your supplier within 2-3 business days of the supplier submitting the Supplier Registration Form (SRF).

  • For suppliers added prior to January 2016, who cannot find their original invitation email, or are foreign suppliers, and the department needs to create a BPO, the department should submit the ARIBA Supplier Network Registration Request webform with supplier number and contact information to request that the invite be sent.

ARIBA Network Enablement Timeline and Status

Timeline: Once a supplier receives the email from UW inviting them to join the ARIBA Network, they must click on the link in the email that says "Click here to proceed" and complete all required ARIBA tasks. Because the process is dependent on the supplier completing the steps to create and configure their account, the process can be as short as one business day up to several weeks.

Status: Please email for information regarding your supplier’s ARIBA Network status.

For suppliers that are not transacting on the ARIBA Network:
  • Non-Catalog purchase orders will require you to include the supplier's email in the "Send PO To" section on your requisition
  • Blanket Purchase Orders (BPOs) are not available to manual (non-ARIBA Network) suppliers. While you can still choose the Supplier when creating a CR, you will not be able to select the Supplier Location to be able to submit your CR.
