For Suppliers (Home)

UC Irvine is committed to maintaining transparent, inclusive, and compliant business relationships with suppliers who support the university’s mission of education, research, and public service. This Supplier Portal provides access to registration, bidding, contracting, and invoicing tools designed to make doing business with the university clear, efficient, and consistent with UC policy and state and federal regulations.

Suppliers are encouraged to review available resources, including guidance on registration, required documentation, small business participation, and Fair Work/Fair Wage compliance. UC Irvine values partnerships that uphold integrity, accountability, and shared success across all areas of procurement. 

How to Do Business with UC Irvine

UCI operates under a decentralized purchasing model, meaning that individual departments and units across campus are empowered to make their own purchasing decisions independently, in accordance with UC and UCI procurement policies. Purchasing decisions are made at the departmental level, by the faculty, staff, or administrators who have a direct need for your products or services.

The best way to do business with UCI is to identify and build relationships with the department or end-user that would benefit most from your products or services. They are your primary point of contact and the decision-makers for their purchasing needs.
