Subcontractor Portal
Every Bid and Every Sub in One Place
Invite your subs and vendors by text or an email and give them one place to bid and stay connected to the job, with no account or extra seat required. What they send back stays connected to your Handoff project, from the winning bid to the work happening in the field.
Your subs get a portal. You get the bid loop closed.
Stop piecing subcontractor bids together by hand
Scope goes out by email. Bids come back as text messages and screenshots. Follow-ups happen by phone, usually twice. By the time you pick someone, there is no single record of what you sent, who answered, or what you agreed to. And the rate you awarded never makes it back into the estimate, so you either key it in again or leave it blank.
The Subcontractor Portal keeps that entire process connected to your estimate. Your AI Teammate turns the scope you already built into a bid request, and subs send their pricing back in a structured format. When you choose a bid, the winning rate goes straight back into your estimate.

Handoff has turned 3-hour estimates into 20-minute estimates ... I give a project scope, any plans and pictures, and it creates the entire estimate for me.

Bid requests
Your estimate becomes the bid request
Your AI Teammate uses the scope already in your estimate to build the bid request, so every sub prices the same work without you rewriting it in an email.
Compare bids
Every bid side by side
Compare structured bids side by side instead of digging through screenshots and messages. Your AI Teammate calls out the differences and helps you see how each bid stacks up before you award the work.
No accounts needed
No accounts, no seats, no onboarding
Subs open a mobile-friendly portal, no Handoff account needed, and you don't need to buy another seat to bring them into the project.
Award & connect
The winning bid stays connected to the project
Award the work and bring the winning rate back into your estimate without entering it again. As the job moves forward, subs can upload invoices through the same portal and you can bring those costs into the project budget.
