UKWhat do the SAM.gov notice types mean?
They mark stages of one procurement: Sources Sought/RFI (market research) → Presolicitation (coming soon) → Solicitation or Combined Synopsis/Solicitation (bid now) → Award Notice (who won). Amendments update an open solicitation, and Justifications explain sole-source decisions.
The notice type tells you what action fits. Sources Sought and RFIs want capability responses, not bids. A Presolicitation says a solicitation is imminent — time to prepare. Solicitation (or Combined Synopsis/Solicitation, the compressed commercial format) is the live, biddable stage with a deadline. Award Notices close the loop and double as competitor intelligence.
WinAContract groups all notices that share a solicitation number, so you see each procurement’s full timeline — from first market research to award — in one place.
