  • The following departments have unique payables processing procedures which require that vendors send the invoices directly to the departments. Invoices for these departments SHOULD NOT be sent to the above Accounts Payable Office address, as it will delay the processing of your payment:
    • Physical Plant - Campus Services
    • Facilities Services/Capital Projects
    • The Library
  • Our Customer Service phone number is 510-643-2199. Customer service representatives are available to assist you between the hours of 9:00 A.M. and 4:00 P.M. Pacific Time, Monday through Friday.
  • We are not a tax-exempt organization. The University of California is subject to State–administered sales and use tax laws to the same extent as private individuals or businesses.
  • A Purchase Order number is required on your invoice. BearBuy is UC Berkeley’s online procurement system. Purchase Orders from the BearBuy system start with BB followed by 8 digits, for example BB00001234. Old Purchase Orders beginning with a 1, 2 or a J will not be valid after December 31, 2012. Invoices without a purchase order number will be returned to you.
  • Be sure that your invoiced items match those on the purchase order. If the quantities differ, or if lines on a purchase order have been combined on your invoice, the transaction will require additional research which may cause a delay in payment.
  • Invoices are generally processed within 10 days of receipt in our office. Depending on the dollar amount and type of purchase, invoices are routed to campus departments for online authorization. Once the approval is completed, the payment will be generated according to the payment terms.
  • Provide your company's taxpayer ID to Accounts Payable. The Berkeley Financial System cannot process a payment without a valid taxpayer ID number. This ensures that you have a unique vendor number in our system and that our external reporting is done properly.
  • Know your vendor number and include it on your invoices if possible. If you are not sure what your vendor number is, contact Customer Service and a Customer Service representative will provide it to you. Refer to your vendor number when making inquiries to our office.
  • We offer EFT (Electronic Funds Transfer) as a preferred payment method. With EFT, the payment is deposited into your bank account 2 business days after the payment is approved. EFT eliminates payment delays and the risks involved with paper checks such as loss, theft, etc. The EFT form and instructions are available on our website. Print a copy of the form, fill it out and mail it to our office. EFT will become effective 30 days after we receive the completed form. For each EFT payment issued, we will email, or send via US Mail, an EFT remittance advice form showing the payment details.
  • Payments for most UC Office of the President (UCOP) departments are processed through UCLA (see exceptions below). If you have payment questions on invoices for UCOP departments, you should contact the department, or call the UCLA Accounts Payable office at 310-794-0197.
