For trade contractors
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.
30-day free trial. No credit card required.
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
Three-section line-item builder (labor, materials, other). Pick from your saved scope templates, set the deposit %, hit send.
02 · Protect
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
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.
Try every feature free for 30 days. Then it's a flat monthly subscription — no tiers, no add-ons, cancel any time from the app.
