Vendor Information


For payment processing, vendors must initially submit a Federal W9 tax certificate and vendor information form.  Our total accounts payable timing is approximately net 45 days because of our required payment authorization process.  You may request the payment schedule for our check printing cycle.  Please allow 30 to 45 days from the time we receive your invoice to printing your check.

For questions concerning invoices or payments, please contact Frances Ramirez, Accounts Payable Clerk at (951) 674-3124 ext. 216 or email
