Federal, state, and local government agencies buy everything from toothpicks and cleaning services to spaceships and cancer research. The key is to determine which government agencies buy the products and/or services you sell and to develop a focused marketing strategy targeting those agencies. Look for opportunities that you are interested in and see what company was awarded the last contract and the terms – you can search https://www.usaspending.gov/ or SAM Contract Opportunities for recent awards.
All departments and agencies of the federal government are required to post contracting opportunities and award information relating to opportunities that are valued over $25,000. In general, the home page of each federal organization will contain a link for business opportunities. Some organizations are now posting opportunities valued below $25,000.
