Your first project is free

Pay for PromaBuild the way you actually bid.

Try the complete workflow on one real project. After that, pay $19 only when you activate another project, or choose a monthly plan when you bid often enough that unlimited projects make more sense.

No credit card required for the trial. Subcontractors never pay to respond to your invitation.

Free trial — not a pricing tier

Prove PromaBuild on one real project before you pay anything.

Your trial includes one project with up to 10 bid packages and 30 bidder invitations—enough to experience the real workflow from package setup through responses and award. If you have not sent an invitation yet, you can reset the trial and start over.

When Pay As You Go fits

Bid occasionally without carrying another subscription.

Prepare the next job in PromaBuild at no charge. When you are ready to contact real bidders, activate that project for $19 once. The project stays available through award and afterward in your history.

When Pro makes sense

Three projects in a month already favor Pro.

Three $19 activations would cost $57. Pro is $49/month and removes the per-project activation step while giving a regular estimator higher ongoing invitation volume and the full single-user workflow.

Start with the project already on your desk.

Build the project, add bid packages and subcontractors, collect responses, and record the award. Your first project is free, and there is no monthly commitment if Pay As You Go fits you better.
