Garage door companies
Missed calls answered by AI and booked as a 15-minute callback
When nobody can reach the phone, GoHighLevel (GHL) hands the call to an AI voice agent and sends the caller a text, and the caller ends up with a 15-minute callback on your calendar. The visit is booked later, by your team, in the field-service tool you already run.
The job
Why the AI stops at a phone call
The callback is where HighLevel hands the customer to your team.
A garage door call tends to come from someone standing next to a door that won't open, a spring that snapped, or an opener that quit. The person who would answer is usually the owner or a tech, and they are on a job. The call rings out, and that caller still needs a human being to talk to.
For a garage door company we built that into HighLevel. When a call goes unanswered, an AI voice agent picks it up and the caller also gets a text, so they can talk or type. Either way the conversation is steered to a 15-minute callback: a short phone call with a person, booked on its own calendar.
Why a callback and not the visit? Because the visit belongs to the field-service tool. That is where the company's crews and routes are planned, and booking visits from HighLevel as well would have meant two schedules drifting apart. So a person books the visit, in the tool that already runs dispatch, and HighLevel has no integration with that tool on purpose.
Two rules shape what the AI asks. Getting a callback should never hinge on the caller knowing a technical detail, such as which kind of spring their door uses; a person sorts that out on the call. And prices stay with people: the AI never states a fixed price, because a firm quote needs someone at the door.
A third rule covers the phone number itself. The number printed on your trucks and tied to your Google listing is never swapped. The AI answers on a HighLevel line of its own. Sending unanswered calls from your existing number to that line is a forwarding setting at your phone carrier, and switching it on is your step, not ours.
If your phones are busy, a person should get the first ring, with the AI as the fallback after a short ring. Every prompt the AI runs and every answer it can give is written in the plan document and approved by you before the build starts.
What we set up
The pieces of the missed-call build
Built in your own HighLevel account, from the plan you approved.
- An AI voice agent on a HighLevel line of its own, for calls nobody reaches
- A text-back that reaches the caller after a missed call
- AI text chat that steers to the same callback
- One calendar for 15-minute callbacks; the AI books nothing else
- Knowledge-base answers in your words, approved before the build
- Plain questions: no caller needs a part name to get a callback
- Your published number left exactly as it is
- No link into your field-service tool, by design
How a setup runs
How the callback build comes together
A 1:1 with Rob
Half an hour on your phones: the number customers dial, who gets the first ring, how long it rings, and where a call goes today when nobody picks up.
Prompts and answers on paper first
The plan document spells out the AI's greeting, what the text-back says, and every answer the AI may give. You approve that wording before we build anything.
Build and test
We build the voice agent, the text-back, the chat and the callback calendar in your account, then test them the way a caller would reach them.
QA report at handover
Each piece comes with evidence and screenshots: the calendar, the text-back, the voice agent's setup and the chat, so you can see what was checked.
Change requests
Want the AI to answer something new? First we tell you whether it fits the agreed scope or is new scope, then we do the work.
What you bring
What we need from you
The number on your trucks
Tell us which number is printed on your trucks, your site and your Google listing. That number stays exactly as it is; the AI gets a line of its own.
Your answers
What callers ask and how you answer them: the area you cover, the jobs you take, your hours. We write the knowledge base from it for you to approve.
The person on the callbacks
Name whoever makes the 15-minute calls. On that call they talk through the door and book the visit in your field-service tool.
Your words for the greeting
How you want a caller greeted and how the text-back should read. Both go into the plan document word for word before we build.
Where it stops
Its reach ends at the callback. The AI books no in-home visit, no fixed price is ever spoken or texted, and your field-service tool receives nothing from HighLevel.
