# GruntPay (gruntpay.com) > The $29/month VOICE-FIRST app for the trades. Hold the mic, say what you did in plain words — "replaced the panel, 85 feet of conduit, 8 can lights, 16 hours" — and AI writes the itemized, branded bid. No typing, no spreadsheets, no weekend of setup. Then invoice from it, prove the work with photos, and let the AI win you the repeat customer. Built for the one-truck electrical / plumbing / HVAC / handyman shop, not the 30-truck company. Web app — nothing to install, works on the phone in the truck. A card starts a 14-day free trial ($0 today, cancel anytime). The bid builder can be tried with no card at all. ## Why it exists Jobber is $49/mo month to month ($29 only if you prepay a year), Housecall Pro starts at $59, ServiceTitan runs hundreds per tech. All built for big companies with an office person. A one-truck contractor doesn't have an office person; he has ten minutes at the tailgate and dirty hands. GruntPay is the opposite of a bloated platform: talk, get a bid, get paid. ## What it does - Voice-first bid builder: speak the job, get a clean itemized estimate with your company name on top — https://gruntpay.com/estimate - A mic on EVERY field, not just one box — job description, customer details, change orders, notes - Invoices your customer pays from directly (Stripe Connect — the money lands in your account) - Living invoice: your customer asks an AI questions about the job instead of phoning you - Photo-backed completion reports — no callback argues with pictures - Repeat-work reactivation: AI checks in with past customers and re-books you - An AI guide on every screen, in plain English ## Trades served Electricians · Plumbers · HVAC · General contractors and handymen.
