Register to Bid

UC Merced strives to provide fair, open and efficient opportunities for all suppliers interested in doing business with the campus.

CalUSource, the UC public bid site, is a self-service portal to register, update supplier information and participate in all UC campus bid opportunities.

For more details on how to navigate CalUSource and manage your events, please review the Supplier Quick Reference Guide.

If you have questions about how to use the site and manage your events, please contact UC Procurement Services Support at

If you are going to be awarded a contract, you will need to complete a more detailed registration and review process as part of the contract award in order to receive a university purchase order.
