How to find U.S. government contracts

Start with the work your company already performs. Combine service keywords with NAICS and PSC classifications, then check the federal agency, place of performance, notice type, set-aside status and response deadline. A relevant code can improve discovery, but it is not proof that the scope, qualifications or contract terms fit your business.

GovBidFit keeps the public opportunity record separate from the private supplier workspace. Public pages help search and compare federal contract opportunities; your company profile and bid notes stay in your browser when you use the workspace.

What are U.S. government tenders?

Businesses looking for tenders in America can use this directory to find U.S. federal procurement notices. SAM.gov calls these contract opportunities; a solicitation may request proposals (RFP), quotes (RFQ) or sealed bids (IFB). Read the notice type before preparing a response, because market-research notices and requests for priced offers require different actions. This directory covers federal SAM.gov notices; state and local authorities publish their own procurement opportunities.

What counts as a federal contract opportunity?

SAM.gov publishes procurement notices from federal contracting offices. Depending on the acquisition stage, these can include sources sought notices, presolicitations, solicitations and combined synopsis/solicitation notices. The notice type helps explain where the procurement is in its lifecycle, but the official notice and amendments determine what action a vendor should take.
