WhatsApp AI agent for car workshops: quote the service, book the bay, stop losing the Saturday rush
A mechanic under a car cannot answer "how much to replace the battery on a Myvi?" for the fortieth time. The customer messages three workshops and goes to whoever quotes first. An AI agent quotes from your own price list, asks for the model and year, books a bay, and the mechanic finds out when the car arrives.
Quick answer
Put a WhatsApp AI agent on your workshop's number with your service and price list as its knowledge. It answers price, hours and location questions, asks for the car model, year and problem, offers real bay slots and sends a reminder the day before. Keep diagnosis, warranty claims and anything about a car already in the shop with the team. ReplyKit does this from $29 a month.
Why workshops lose the Saturday rush
Auto enquiries are urgent and price-led. A flat battery, a warning light, a tyre with a nail: the customer wants a price and a time, now, and will take the first workable answer. The HBR research on lead response found the odds of qualifying a lead fall sharply after the first hour; with a car that will not start, it is the first ten minutes. The questions are simple, price-list questions. The person who could answer them is under a car.
What the agent handles
Automate
- Prices for standard jobs from your list: battery, tyres by size, oil service, brake pads, aircon service, tinting, detailing packages.
- Opening hours, location, whether you offer pickup or a loaner.
- Collecting the model, year, plate and a description of the problem, and saving them to the lead's card.
- Photos: a warning light, a tyre, a dent. The agent describes what it sees and books an inspection rather than diagnosing.
- Booking a bay into real slots, with a reminder the day before.
- Voice notes from customers on the road, transcribed and answered.
- Malay, English or Chinese, whichever the customer uses.
Keep with a person
- Diagnosis and repair estimates for anything not on the list. The agent says an inspection is needed and books it.
- Warranty and insurance claims.
- Progress on a car already in the shop, and any complaint.
- Parts availability you have not written down.
- Anyone who asks for the boss.
The rule that keeps quotes safe: the agent quotes only prices you have written down, by model or by tyre size, and says "we need to see the car" for everything else. ReplyKit answers only from your knowledge and hands over when it does not know, so a missing price becomes an inspection booking rather than a made-up number.
Setup for a workshop
- Use a dedicated number. ReplyKit connects your number through Meta's official WhatsApp Business Platform: keep the number you already use in the WhatsApp Business app and the agent works alongside it, or add a dedicated number. Personal WhatsApp numbers cannot be connected. Keep your long-standing number out of it; details in Meta's messaging limits explained
- Upload your price list as a PDF, organised by job and by common models. Tyres by size, batteries by model, services by engine size.
- Write the unwritten rules as text: deposit for ordered parts, how long each job takes, what to bring, whether walk-ins wait.
- Add bays as services with durations: a tyre change is 30 minutes, a full service 90, tinting a half day. Set your hours.
- Instruct the boundaries: no diagnosis from photos, warranty and insurance to a person, and always ask model, year and problem before quoting.
- Connect the number through Meta's sign-in and test from your own phone with a photo of a warning light. It should book an inspection, not name the fault.

A chain with several branches runs one agent and number per branch on the Growth plan, each with its own prices and hours and one shared inbox.
Frequently asked questions
Can the agent give a repair quote?
It quotes fixed prices you have listed, such as a battery for a given model or tyres by size. For anything else it books an inspection rather than guessing. It never diagnoses from a photo.
Can it book a bay?
Yes. Set bays as services with durations and your hours, and it offers real slots, books them, sends a reminder the day before and adds the booking to your calendar export.
What does it do with photos?
It can describe an image, so a warning light or a tyre photo gets a sensible reply, but it is instructed to book an inspection rather than name the fault.
Will it save the car details?
Yes. Model, year, plate and the problem are saved to the lead's card in the built-in CRM, so the mechanic sees them before the car arrives.
How much does it cost?
From $29 a month for one number, one agent and 1,000 AI replies, with booking and a leads list included and no per-message fees. 7-day free trial.
