Welcome to UC Davis! We look forward to working with you.
What to Do First?
Please note that registering as a UC supplier does not constitute an agreement for guaranteed future business, but can provide you with opportunities for working with the university in the future.
1. Are you a supplier who has not done business with the University of California before? Start by registering as a University of California supplier at the CalUSource website.
2. Complete the registration request process in Aggie Enterprise, the UC Davis financial and purchasing system. NOTE: A new registration platform, PaymentWorks, is coming to UC Davis in 2025.
3. If you are a certified small, diverse, or veteran-owned supplier, complete the online registration form for small and diverse businesses (Davis campus) and refer to the online resources and instructions if desiring to do business with the UC Davis Health campus.
- Certified small, diverse, or veteran-owned business owners are also encouraged to visit the informational page designed just for our small and diverse suppliers.
Ensuring a Good Relationship with UC Davis
- Please be advised of an ongoing fraudulent email scam targeting university suppliers.
- All suppliers working with the university are to review and follow the University of California Sexual Violence and Sexual Harassment policy.
- Keep us supplied with latest catalogs and price lists in electronic format.
- Keep us informed of situations that may delay order fulfillment (e.g., back order situations, plant closures, impending shortages or strikes).
- Do not offer gifts or gratuities that may influence or affect university purchasing decisions. Incentives should take the form of quality or price considerations.
- Promptly provide us with an accurate certificate of insurance and proof of workers’ compensation whenever requested.
