Sell an after-hours voice agent to a repair shop

Mark sold a voice agent to a truck and trailer repair shop that was missing calls. The Retell agent picks up after hours and on overflow, collects the caller's details and issue, and a Make.com scenario sends that to email, Slack or WhatsApp and logs it in Google Sheets. No CRM or booking. He closed it with one PandaDoc doc that held the proposal, contract and invoice, for $1,800 upfront and $400 a month.

The template

Adapted from the steps the source described. Fill in the [BRACKETS].

You answer after-hours and overflow calls for [SHOP NAME], a [TYPE] repair shop. 1. Greet and say the team is busy or closed, and you'll take the details so they call back fast. 2. Collect: name, company, callback number, vehicle/unit type, location, what's wrong, how urgent (stranded or not). 3. Read the number back to confirm. 4. Don't give prices or repair times. If they're stranded, say you'll flag it as urgent. 5. End the call politely. After the call, send a summary to [EMAIL / SLACK / WHATSAPP] with URGENT in the subject if stranded, and add a row to [SHEET].

Approval rule

🛡
The agent takes messages only. No prices, no bookings, no promises on repair times.

Set it up

  1. Find a shop that misses calls (ask them, or call after hours).
  2. Build the agent and the Make.com scenario.
  3. Set call forwarding for after hours and busy lines.
  4. Send one document with proposal, contract and payment link.
  5. Charge setup plus a monthly fee that covers usage and changes.

Common failures

⚠
  • Promising bookings when the shop's system has no integration; start with message-taking.
  • Forwarding all calls on day one; start with after hours.

Variations

  • Plumbers, HVAC, towing.
  • Add SMS to the caller confirming the shop got the message.
