How Montana Bidroom works — for GCs, subs, and property owners.
General contractors run bid rooms. Subcontractors browse, get invited, and submit bids. Property owners post projects and receive contractor interest. Contractors self-attest credentials — Montana Bidroom connects the workflow.
Start with eMACS. Finish with Montana Bidroom.
Montana's public construction projects are already listed on eMACS — for free. Montana Bidroom is where you manage everything that happens next: trade packages, secure sub invites, AI scope extraction, and live bid comparison. No plan-room subscription to find public projects.
Your subs don't need an account.
When you invite a sub, they receive a unique secure link. They click it and land directly on the plan room — no login, no account creation, no friction. They download drawings, enter their price, attach their proposal PDF, and hit Submit.
