Stop Running Your Business on Paper and Spreadsheets
You're great at the work. But chasing invoices, losing track of estimates, missing calls when you're on a job — that's what kills momentum. BuildBillRX puts your entire business in one place, on the phone that's already in your pocket.
Jobs & Clients — Always Organized
Create jobs, assign them to clients, track status from lead to completion. Notes, photos, job history — all in one place. No more digging through texts to find a client's address.
Send Estimates. Get Paid. In Minutes.
Build professional estimates in seconds, convert to invoices with one tap, and get paid online via credit card, ACH, or Apple Pay. Your clients pay from their phone. You get notified instantly.
Contracts Signed on the Spot. No Printer Needed.
Send legally binding contracts to your clients' phones. They sign with their finger. You get a signed copy instantly. No printing, no scanning, no chasing paper.
Know Your Real Profit on Every Job.
Log expenses as you go. Track mileage automatically with GPS. Connect your bank account and categorize transactions automatically. Stop guessing — know exactly what each job costs.
Your Crew. Organized.
Add crew members, assign them to jobs, track clock-in and clock-out with GPS timestamps. Review and approve timesheets. Manage subcontractors and vendors. Everything in one place.
Ask Rex — Your AI Business Assistant.
Ask Rex anything about your business. "What's my most profitable job this month?" "Which clients have unpaid invoices?" Instant answers. No reports to run.
Everything in One App
Your Phone Answers Itself.
You Focus on the Work.
Most contractors lose leads because they're too busy to answer the phone. With BuildBillRX Elite, your AI receptionist answers every call — even at 11pm, even when you're on a ladder. She collects the caller's name, what they need, their address, and a callback number. You get a push notification instantly.
