SAM.gov is the single public place where federal agencies post contract opportunities, but not every notice is an invitation to bid. The site uses a set of notice types, and each one tells you something different about where the agency is in its process and what it wants from industry. Reading the type before reading the text saves time and helps you respond in the right way.
Early-stage notices
Sources sought. The agency is doing market research. It wants to know which firms can perform the work and, often, whether enough small businesses exist to set the requirement aside. Responding does not obligate you to bid, but it can shape the strategy in your favor.
Special notice. A catch-all for announcements that are not solicitations: industry days, draft solicitations released for comment, changes to an agency’s ordering procedures or general information about a program. These are worth reading because they often precede formal requirements.
Presolicitation. The agency intends to issue a solicitation and is giving advance notice. The FAR generally requires a waiting period between this notice and the solicitation itself, which gives you time to prepare teams and gather documents.
Notices that ask for offers
Solicitation. The formal request. It will be a request for proposals, request for quotations or invitation for bids, with instructions, a due date and attachments. This is the notice most firms watch for, but by this point the strategy is set.
Combined synopsis/solicitation. Used mainly for commercial products and services. The notice and the solicitation are one document, and response periods are often short. If your firm sells commercial items, these deserve close attention because they can appear and close within days.
Notices after a decision
Award notice. The agency announces who won, often with the contract number, value and a brief description. Award notices are a research gold mine: they show who your competitors are, what agencies pay and which offices buy your type of work.
Justification and approval. When an agency awards without full and open competition, it must generally publish its written justification. Reading these shows which requirements go sole source and why.
Fair opportunity or limited sources justification. A similar document for orders placed under multiple-award contracts or Federal Supply Schedules without giving every contract holder a chance to compete.
Other notice types you may see
- Intent to bundle requirements, which signals that separate contracts may be consolidated into one
- Sale of surplus property, which is not a contracting opportunity at all
Using notice types in your searches
Saved searches on SAM.gov can filter by notice type, NAICS code, product service code, agency and location. A sensible setup includes one search for sources sought and special notices, where early engagement pays off, and another for solicitations and combined synopsis/solicitations, where deadlines are near. Review award notices periodically rather than daily. Whatever you set up, read each notice fully; the type tells you the stage, but the attachments tell you the requirement. The site itself, sam.gov, publishes guides to its search features and notice definitions.
