For trade contractors

Estimate fast.
Protect the scope.
Get paid.

BidBildr is the mobile-first estimating, invoicing, and change-order app built for handymen, GCs, painters, drywallers, and small trade shops who still spend Sunday nights writing up bids.

Get Started

30-day free trial. No credit card required.

One app. One workflow. Cash in the bank.

Estimate-to-deposit in under ten minutes, from the cab of your truck. Everything customers see — the estimate, the invoice, the change order — opens in their browser without an app install.

01 · Estimate

Build it on the truck

Three-section line-item builder (labor, materials, other). Pick from your saved scope templates, set the deposit %, hit send.

02 · Protect

They sign before you start

Customer opens the link, signs with their typed name, pays the deposit by card. ESIGN-compliant electronic signature with an audit hash.

03 · Get paid

Convert in one tap

Approved estimate becomes an invoice. Record cash, check, Zelle, or take a card. Mid-job scope creep? Send a change order — it lands on the same invoice.
