A construction bidding system and method includes manager, general contractor and subcontractor workstations that communicate with a server hosting a website over a network such as the Internet. The server also communicates with a number of databases. A manager enters project information into a project database and selects general contractors from a general contractor database. The manager sends each selected general contractor an invitation to bid. A general contractor receives the invitation to bid, reviews the project information and selects subcontractors from a subcontractor database. The general contractor sends each selected subcontractor an invitation to bid. A subcontractor receives the invitation to bid and responds with bid information that is entered in to a bid database. The general contractor uses the bid information from the subcontractors to prepare and submit a bid to the manager.
