Starting an AI voice agent business: real examples and pricing
A voice agent answers the phone for a business. It takes the caller's details, books a slot or flags the call as urgent, and sends the owner a summary. The businesses below were missing calls, slow to call new leads back, or spending too much staff time on the phone. That makes this one of the easiest agent services to explain to a client.
Here are 5 people who sold one, with who the client was, what they charged, the tools they used, and a prompt you can adapt.

The recipes
Each has the call script, setup steps and what the agent must never do.
A voice agent answers calls for trades businesses, books jobs, texts back missed callers and chases quotes. Sold as setup fee plus monthly.
Calls get answered, details collected and a survey slot booked, then an SMS goes out with the estimate and a payment link.
One tested receptionist template, cloned per location, covering missed calls and after hours for franchise owners.
A new ad lead gets an AI voice call within 2 minutes, then WhatsApp and email follow-ups until it books.
A voice agent covers after-hours and overflow calls for a truck repair shop, sends each call to the team and logs it.
How they kept it simple
- Take messages before taking bookings. The repair shop agent collects details and sends them on. No CRM, no booking, no prices. (repair shop)
- Start with after-hours calls. Forwarding every call on day one is listed as a common failure. Cover after hours and overflow first.
- Book a visit, not a price. The removals firm's main lesson: book a survey instead of quoting on the phone. Staff set the final price. (removals firm)
- Follow up on what the phone misses. Missed callers get a text within 30 seconds, quotes get follow-ups on day 2, 5 and 10. (UK trades)
- Template it. The franchise rollout builds one agent, tests it, then clones it per location. (franchise)
Common questions
How much do people charge for an AI voice agent?
In these cases: $1,800 upfront plus $400 a month for a repair shop; £1,500 setup plus £275 a month for UK trades, later £2,500 plus £400; $2,000 for a clinic's lead callback build; and $499 a month per franchise location (as claimed in an episode title).
What tools do they use?
Retell AI with Make.com or n8n, HighLevel's built-in Voice AI, and one build on Zapier, Twilio, Google Calendar and OpenAI for about £140 a month. Summaries go to email, Slack, WhatsApp or a Google Sheet.
Should the voice agent give prices or diagnoses?
Not in these builds. The repair shop agent gives no prices or repair times, the removals agent books surveys and leaves pricing to staff, and the clinic agent sends medical questions to staff.
