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 is the official start of a competitive procurement. It is 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 recurring business-development problem.

The notice also sets the ground rules a bidder should read 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. The required advertising period is often fixed by statute, which makes deadlines predictable but easy to miss across so many sources. Nonlinear monitors federal, state, and municipal bid portals and updates your opportunity log when a new notice appears.
