Procurement Opportunities

SOS Historically Underutilized Business (HUB) Program

SOS actively promotes HUB participation in agency purchases of supplies, materials, services and equipment. We encourage HUB businesses to register with Texas Comptroller of Public Account (CPA). See CPA's Program site for the "how to's" of getting on the Centralized Master Bidders List (CMBL) and becoming HUB certified.

What SOS looks for in a vendor

Purchase Orders Issued by the Office of the Secretary of State

A purchase order constitutes a legal contract between the agency and a vendor. Only SOS purchasers are authorized to issue an official SOS purchase order to procure goods and services on behalf of the agency.

Office of the Secretary of State
James E. Rudder Building

Receiving hours are from 8 a.m. – 12 noon and 1 p.m. – 5 p.m., Monday through Friday (except State holidays). All packing slips and cartons must include the SOS purchase order number. The vendor is responsible for making deliveries to the correct address as specified on the purchase order.
