Established in 1989, Sales Opportunity Services, Inc. (SOS) is America's source for government business opportunities and related procurement data.

From America's Fortune 500 to around-the-corner Mom and Pop businesses, SOS assists businesses by doing the leg-work in finding for new and repeat government business opportunities.

SOS also provides ancillary databases that provide additional procurement information that would otherwise require venders to search multiple sources to obtain.

SOS combines nationwide coverage of hundreds of government purchasing facilities with custom sorting to ensure that you see every available opportunity for every one of your products. SOS subscribers achieve a savings of better than 90% on time spent searching for opportunities.

Custom sorting permits you to match opportunities by part number, competitor, FSC group, or keyword. Changes to match criteria can be done by phone or e-mail, and are effective the next business day.

SOS's Subscriber Service and Technical Staff are available daily, Monday through Thursday from 8:00AM to 5:00PM (ET) and Fridays from 8:00AM to 4:30PM (ET), to assist you in maximizing the use of your SOS service subscription.
