Vendor Registration - Fairfax Vendor Internet Portal (VIP)

Thank you for your interest in doing business with the county. All vendors interested in doing business with Fairfax County Government and Fairfax County Public Schools are expected to register in the Fairfax VIP. The Department of Purchasing and Supply Management (DPSM) uses the list of VIP vendors to prepare a bidders list for all formal procurements (goods and/or services greater than $50,000). Notices of solicitation are sent to all VIP vendors on each bidders list for purchases of specific goods and/or services via email. Email is the county's primary medium for communication with vendors; as such, it is very important that a company's email contact information is accurate.

DPSM encourages the use of D-U-N-S numbers and recognizes the Department of Minority Business Enterprise (DMBE) and other business development entities' business classification (SWaM) certifications. We encourage all bidders to review the online documentation at the Fairfax VIP web site prior to registration.

Vendors interested in doing business with Fairfax County are also encouraged to register with eVA, the commonwealth of Virginia's electronic procurement portal. eVA registration enables vendors to view solicitation opportunities with state and local governmental entities across Virginia. Fairfax County also uses eVA to purchase goods and/or services under $50,000.

If you would like additional information regarding vendor registration please contact the VIP Team at 703-324-8477, TTY 711.

Visiting Other County Offices

Vendor sales efforts to a county agency are not prohibited and may be the best way to achieve small sales (i.e., sales less than $10,000). County agencies often request product and service information to keep current with the latest technologies, materials, sources of supply, etc. Furnishing sales literature or other product information is considered normal sales effort. However, such requests do not imply that you will receive an agency's order. Depending on a number of conditions, an agency's final requirement may result in a solicitation being issued by the Department of Purchasing and Supply Management.

Product Demonstrations

Similar to sales visits, product demonstrations are considered normal sales efforts. Vendors often have a product or service that may be of interest to many agencies within Fairfax County government. In this case, the Department of Purchasing and Supply Management can make arrangements for "product demonstrations" where a number of similar vendor products or services may be demonstrated in one central location (similar to a "product expo"). You should contact the appropriate buyer/contract administrator or Contracts Division Director for additional information.

The Department of Purchasing and Supply Management is a member of several professional associations that sponsor vendor presentations:

The National Institute of Governmental Purchasing (NIGP) - NIGP hosts an "Annual Forum and Products Exposition" where vendors may demonstrate their products/services to a large number of U.S. and Canadian governments. Additional information may be obtained by calling NIGP at 703-736-8900, TTY 711 or email to:

The Virginia Association of Governmental Purchasing (VAGP) - VAGP hosts two conferences a year that includes vendor product demonstrations. For more information about participating in these conferences, you may visit VAGP web site.
