The Procurement Division purchases all supplies and services for the efficient operation of City departments and fosters good business relationships between suppliers and the City.

Purchases are made under the authority granted in the City Charter. Competitive bids are solicited and not subject to negotiations. Awards are made to the best regular responsible bidder meeting specifications and on the basis of the lowest ultimate cost to the City.


Vendor Self-Service Portal Information

A new registration platform is available for businesses that partner with the City. Vendor Self-Service (VSS) allows vendors to create and manage a vendor profile. It is the single best approach to conducting business with the City.


Submitting Invoices

The VSS portal to submit invoices is now available. See the invoice submission guide below for step-by-step instructions. Please contact the VSS team by phone at (209) 937-8357 or email if you have questions or need additional support.



Start by checking to see if your business is listed on the Vendor list, then select the appropriate guide to assist you through registration.

Local Business

Local businesses are an important part of a competitive bid process. The City takes steps to maximize the use of local business enterprises in purchasing and contracting activities by providing information about the City's procurement process and procedures.

For all instances where vendor personnel enter City property to repair, install, service, construct and consult, the City requires a certificate of insurance verifying coverage. Whenever insurance is required on a purchase order, the vendor is supplied with complete requirements for coverage. For more information, please view the Risk Services or contact Risk Services


Purchase Order Numbers

All purchases charged to the City of Stockton require a purchase order.  If an individual calls and attempts to place an order without a City purchase order number, request an authorized purchase order number and obtain the name and department of the individual.  The purchase order number is vital to doing business with the City and ensures payment.



There may be times during an emergency when an order must be placed after hours or on weekends when the Procurement Division is closed. During an emergency, purchases without purchase order numbers will be approved. Be sure to obtain the person's name and department and request identification if the order is placed in person. 


Department personnel are instructed to obtain a purchase order number from the Procurement Division the following business day. The employee who placed the order will contact you with an authorized purchase order number.


Purchase Order Terms

By providing any goods or performing any services in response to and referenced in the City's Purchase Order, the supplier/firm is specifically acknowledging the understanding and agreement to comply with and be bound by the City of Stockton's Terms of Purchase.
