All orders must be delivered to the address specified on the Purchase Order. Vendors should not deliver goods to an alternate address unless authorized by the Purchasing Services Division as the processing of your payment will be delayed.

The Purchase Order is the City's contract with you. Any changes to the contract must be approved in writing by the Purchasing Services Division.
