Built for small general contractors

Know who is bidding, what they quoted, and who you are awarding—without another spreadsheet.

PromaBuild gives GCs one place to create bid packages, invite subcontractors, track participation, collect pricing, compare responses, carry self-perform numbers, and record the award.

No credit card to start. After your free trial project, pay $19 per project or choose a monthly plan. Subcontractors can respond without an account.

Know who is bidding

See invited, viewed, bidding, declined, and submitted status without chasing your inbox.

Compare the numbers

Keep subcontractor pricing, attachments, notes, and your own self-perform estimate together.

Keep the decision

Record the award and preserve the bid history with the project instead of losing it in email.

One complete bidding workflow

Project → Bid packages → Subcontractors → Responses → Award

Focused bid management that works alongside the estimating, accounting, and project-management tools you already use.

Your first project is free

Test PromaBuild on a real bid before deciding how you want to pay.

Run one trial project with up to 10 bid packages and 30 bidder invitations. Collect responses, use self-perform estimates, upload documents, compare pricing, and track the award. If you have not sent an invitation yet, you can reset the trial and start over.

If PromaBuild earns a second project:

Activate that project for $19 once—no subscription—or choose Pro at $49/month when you bid often enough that unlimited projects make more sense.

Easy on subcontractors

Your bidders do not have to adopt another platform.

Each subcontractor gets a private invitation link where they can mark bidding or declined, submit pricing, add notes, and attach documents without creating a PromaBuild account.
