What is a Bid?
A bid is a written offer provided by a contractor to a homeowner or project owner, detailing the proposed price, scope of work, and specific conditions under which the contractor is willing to perform the work. Bids are essential in construction and renovation projects as they allow project owners to compare different contractors’ offers and make informed decisions.

Real-Life Example
Example Scenario: Receiving Bids for a Kitchen Renovation A homeowner plans a kitchen renovation and issues an RFP to several contractors. Each contractor visits the site, reviews the project requirements, and prepares a bid detailing the scope of work, cost estimate, timeline, and terms. The homeowner receives multiple bids and evaluates them based on price, contractor qualifications, and proposed timeline. After careful consideration, the homeowner selects the best bid and awards the contract to the chosen contractor, who then begins work on the kitchen renovation.
