Doing Business with UCR
UC Riverside works with suppliers to support the University’s teaching, research, and operational needs. Campus departments identify their business needs and initiate purchases, while Procurement Services supports sourcing, contracting, and purchasing activities.
If a UCR department intends to purchase from or make a payment to your organization, the department will initiate the supplier registration process.
New to UCR?
You do not need to independently register in UCR’s Supplier/Payee Portal before a department is ready to do business with you.
When a UCR department needs to establish your organization as a supplier, you will receive an email invitation with a secure link to complete your registration.
Registering as a UCR supplier does not guarantee future purchases or a specific volume of business.
How Supplier Registration Works
Complete your registration promptly after receiving an invitation to help avoid purchasing or payment delays.
| Step | What Happens |
|---|---|
| 1. UCR Department Initiates the Request | A UCR department identifies the need to do business with your organization and submits a request to establish you as a supplier. |
| 2. You Receive an Email Invitation | You receive a secure registration link to the UCR Supplier/Payee Portal. |
| 3. Complete Your Supplier Profile | Follow the registration instructions and provide the requested business, tax, payment, and other applicable information. |
| 4. UCR Reviews Your Registration | UCR reviews the submitted information and completes the applicable supplier setup so purchasing and payment activity can proceed. |

- Federal tax documentation, such as a W-9 or applicable W-8
- Applicable California tax documentation
- Products and services information
- Payment and remittance information
- Small or diverse business certifications, if applicable
- Insurance information or certificates, when required
Providing complete and accurate information helps UCR establish your supplier profile and reduces potential delays.
Understand the Different Supplier Systems
UCR and the University of California use different systems for supplier registration, sourcing, and supplier discovery. Registering in one system does not necessarily complete registration in another.
| System | What It’s Used For | How to Get Started |
|---|---|---|
| UCR Supplier/Payee Portal | Used to establish supplier information in UCR’s financial system for applicable purchasing and payment activity. | A UCR department sends you an invitation when it needs to establish your organization as a supplier. |
| CalUsource | The University of California’s eSourcing platform for supplier registration and sourcing opportunities. | How to become a UC Supplier |
