*Students should be hired as employees: A department wishing to pay a student for the provision of services should hire the student as an employee on a limited appointment. Students providing services should not be paid as suppliers, as it is unlikely a student will be in a true independent contractor relationship with the University, as defined by IRS regulations. If the department believes it has an exceptional situation, they need to contact their Campus Buyer for instructions on how to proceed.
**Transactions with Employees are discouraged: The University generally prohibits transactions with employees, because of the potential for conflict of interest. For more information on employee-vendor policies, and department’s responsibilities see Conflict of Interest.
***Cash or Check Payment Refunds: RefundSupplier requests do not require a TIN (SSN or EIN) and do not require a certification signature. Refund Supplier should be used to refund a cash or check payment.
- Select Refund Supplier at the top of the form
- Section 1: Complete Name, Order Address, Order Phone Number
- Section 2: Complete Name, Phone and Email for UC Berkeley Staff Contact
If an individual is providing a good or service, they are considered a New Supplier.
