Accounts Payable section of the Accounting Office serves as a support function to the UC Riverside community by performing disbursements functions in the Procure to Pay (P2P) process. Accounts Payable is responsible for ensuring that payments for all purchases and expense reimbursements are processed and reported in accordance with university policy, state and federal laws and regulations. At UCR, although many purchases are decentralized, all invoices for payments must be submitted to Accounts Payable. Other non-procurement related payments, such as reimbursements, must be submitted via our on-line systems (i.e. ePay, iTravel) in order to be paid.
