How federal agencies award contracts
Each agency buys through its own contracting offices. Purchases above the micro-purchase level are usually posted as open government contracts on SAM.gov, and many are set aside for small businesses. The federal government has a goal of awarding at least 23% of its prime contract dollars to small businesses.
Knowing which agencies buy what you sell, and which companies already win that work, helps you choose where to bid. The figures here are contract obligations reported on USAspending.gov.

For a small business, civilian agencies often buy everyday services close to home: cleaning, landscaping, building maintenance, IT support and training. Open any agency to see what it buys.
