What is a notice to bidders?

A notice to bidders (or “invitation to bid” / “advertisement for bids”) is the public announcement that a project is open for bidding — it identifies the work, the agency, where to get documents, and the date, time, and place bids are due.

It's the official starting gun for a competitive procurement, published so that all prospective bidders learn of the opportunity at the same time and on equal footing. For contractors, catching these notices early across dozens of agencies and portals is a perennial business-development headache.

The notice also sets the ground rules a smart bidder reads before deciding to chase the job: the bid date and delivery method, any license or prequalification needed to bid, bonding requirements, and whether a pre-bid meeting is mandatory. Agencies publish it through legal advertisements, plan rooms, and procurement portals, and the required advertising period is often fixed by statute — which makes deadlines predictable but easy to miss across so many sources. Nonlinear solves that directly: its AI-driven monitoring continuously scans federal, state, and municipal bid portals and updates your opportunity log the moment a new notice appears — so you find qualified work without manually trawling sites.
