An AI Receptionist for Local Trades

Build a simple AI phone agent that answers a contractor's missed calls 24/7, takes the job details, and texts them a summary. Sell the setup plus a monthly upkeep fee to plumbers, HVAC shops, roofers, and salons.

The idea

For a service business, a missed call is a missed job — and most small shops can't afford a front-desk person. Freelancers on Upwork already sell basic "missed call text-back" builds for $35–$175, which proves buyers exist but also shows the race-to-the-bottom price. Your play is the done-for-you build plus a retainer to keep it running.

Who pays

Local trades that live and die by the phone. The tell: a 4-star Google listing, ads running, and nobody answering after 5 PM.

The honest numbers

• Startup cost: effectively $0. Retell AI runs about $0.07/minute pay-as-you-go; Synthflow has a $29/mo starter with a free trial. The trial builds your demo; the client's first payment covers the rest.
• What to charge (estimates): $300–$600 setup, $100–$250/month upkeep and usage.
• Realistic beginner math: one client at $400 setup + $150/mo is a real evening project. Two or three clients in a few months = $300–$750/month recurring. This is not "$50k/mo AI agency" — that's the screenshot case. This is a few hundred a month of real money.
• Time to first dollar: 2–6 weeks. The build takes an evening; the time goes to finding an owner who says yes.

How to start

1. Pick your tool: Synthflow (visual, no-code) or Retell AI (more control, cheaper at low volume). Either can greet the caller, take name/number/job details, book into a calendar, and text a summary.
2. Build the demo on a fake business — "Boise Plumbing Pros," five questions, a booking, an SMS summary. Test it by calling it yourself.
3. Record a 2-minute Loom of you calling the demo. That video is your entire sales pitch.
4. List 20 targets: local trades with good reviews and obvious phone gaps. Pitch with the Loom link and a free 2-week trial on your dime (costs you a few dollars in minutes).
5. Price plainly: $400 setup, $150/month. First client, take what they say yes to — you're buying a testimonial.
6. The deliverable is a working phone number that answers, wired into their real line. Show them the call-log dashboard so they can see it working.

Watch-outs

Business texting in the US needs A2P 10DLC registration (~$5/mo per location, a few days to approve) — go voice-only until a client is paying. And watch voice minutes: a busy shop burns through included minutes fast, so price the retainer at roughly 2x expected usage.

First move tonight: open a Synthflow free trial, clone the appointment-booking template, and get it to say a business name and ask for a callback number. Hearing it work once is the whole unlock.
