PlanHub

PlanHub is free construction plan room and bid management software that allows general contractors to post projects, send bid invites, share information with subcontractors, suppliers, and vendor. There is no limit on the number of users per company.

Subcontractors can register for free and start on a free trial to view projects, download project specs, and submit a bid. After the free trial ends, the user can choose to go on a PlanHub Basic Plan, or upgrade to PlanHub Premier.
