Car repair garages on WhatsApp: book jobs and keep customers updated from the workshop

Why drivers message the garage

Drivers message because the garage phone rings out when everyone is busy, and because a message lets them send the registration, a photo of a warning light or the exact time they can drop off. Many keep the garage number from their last visit. They expect an answer the same morning, and if they do not get one they ring the next garage on the list.

Most messages are bookings, prices for standard work and "is it ready?". A smaller number describe a noise, a smell or a warning light. Those need someone who knows cars, because the honest answer can be "do not drive it".

The rule about safety

The agent never tells anyone their car is safe to drive, and never guesses what a fault is. When a driver describes a symptom, it collects the registration and a short description, offers the first inspection slot and hands the chat to a mechanic. Your note should include a line for urgent signs such as brake problems, steering problems, smoke or a flashing engine light, telling the driver to stop driving and call the garage.

What customers ask on WhatsApp

• Can you fit my car in for an MOT this week?
• How much is a full service on a 2017 Ford Focus?
• Is my car ready yet? I dropped it off this morning.
• Can I leave the car before 8am and the keys in the box?
• My engine light has come on, is it safe to drive?
• Do you do air conditioning recharges?
• Can you send me the invoice for my last visit?

What the agent answers

• Booking MOTs, services and standard jobs into the diary, with drop-off and collection times.
• Prices for standard work from your price list, such as MOTs, services and tyre fitting.
• Telling customers their car is ready, once the workshop marks the job done.
• Drop-off arrangements, key boxes, courtesy cars and opening hours.
• MOT reminders to customers whose test is due, in your wording.
• Sending a copy of an invoice or a booking confirmation you have already prepared.

What it always hands to you

• Any symptom: noises, smells, leaks, warning lights, vibration, smoke or a car that will not start.
• Whether a car is safe to drive, which is always a mechanic's call.
• Quotes for repairs beyond your standard price list, and any extra work found during a job.
• MOT failures and advisories, which need someone to explain them.
• Complaints, warranty claims and disputes about a bill.
• Insurance and accident work.

Never let the agent approve extra work

The most expensive misunderstanding in a garage is extra work the customer did not agree to. Tell the agent that it never approves, prices or recommends additional repairs. When the workshop finds something, a person messages the customer with the price and waits for a clear yes. The agent can follow up on the booking, but the "go ahead" has to come from the customer to your team.

The WhatsApp limits that matter here

Replies to people who message you are not held back by the warm-up, so customers get answers from the first day.

Set it up in an afternoon

1. Write a garage note: services and prices, opening hours, drop-off rules, the urgent-signs wording and the topics that always go to a mechanic. There is an example below.
2. Connect the garage's WhatsApp number in Spaces. You scan a QR code with the phone that has the number, the same way you would link WhatsApp on a computer. The phone keeps working as normal afterwards.
3. Connect your AI agent using the steps on our agents page. Chat apps such as Claude or ChatGPT reply when you ask them in a chat, so for replies around the clock use an always-on agent such as Claude Code, Codex, OpenClaw or Hermes. Give it the note. Spaces does not connect to booking diaries, but your agent can reach one through its own tools if you set that up.
4. Decide how the workshop marks a job done, so the agent only says "ready" when it really is. A shared sheet or a quick message to the agent both work.
5. Agree which mechanic picks up handed-over chats, and when. A reply within a couple of hours is a good rule for symptoms.
6. Set up MOT reminders for customers whose test is due, scheduled for sensible times. Scheduled messages can carry working hours of their own.
7. Read the handed-over chats every week for the first month and add missing answers to the note.

A sample garage note

Keep it short and update the prices when they change. Here is the shape of one, with example details.

GARAGE: Northgate Motors, Unit 4, Kiln Road. Open Mon to Fri 8am to 5:30pm,
Sat 8am to 12pm.
DROP OFF: 8 to 9am. Key box by the door for early drop-offs.
Courtesy car: one, book ahead.

PRICES (examples): MOT £54.85. Interim service from £129.
Full service from £189 (petrol), £209 (diesel). Air con recharge £69.
All other work is quoted by a mechanic after a look.

READY: only say a car is ready when the job sheet says DONE.

URGENT SIGNS (say exactly this, then hand over):
'Please don't drive the car and call us on 01234 567890.'
Use for: brakes, steering, smoke, burning smell, fuel leak,
flashing engine light, overheating.

NEVER: say a car is safe, guess a fault, approve or price extra work.

Updates during the day

The question every garage hears most is "is it ready yet?". The agent can answer it well, but only if it knows. Decide how the workshop tells it a job is finished, and keep that step simple, because nobody wants another screen to update. A short message such as "AB17 CDE done, £189" from the workshop phone to the agent is often enough.

Then the agent can tell the customer, share the collection times and answer "can I pay by card?" without anyone stopping work. If a job is running late, tell the agent and let it update the customers affected with a short apology and a new time.

A second example: an MOT reminder

MOT reminders work well because the customer expects them and usually wants to book. Names and details are examples.

Send reminders only to customers whose MOT or service is really due, and stop the moment someone says they have sold the car or do not want reminders. Spaces refuses further messages to anyone who said stop in that chat.

Common mistakes garages make

• Letting the agent say "it's probably fine". It should never judge a symptom.
• Saying a car is ready before the workshop has finished, so the customer arrives to find it on the ramp.
• Quoting repairs from guesswork. Only standard work from your price list should be quoted.
• Messaging every customer from the last five years about a winter check offer. Keep messages to people who are due or have asked.
• Using a brand-new WhatsApp number. A number with a real history of conversations is far safer.

Who you message

In short

For a garage, an AI agent on WhatsApp keeps bookings and updates moving while the team works on cars. It books MOTs and services, quotes standard work and tells customers when their car is ready. Every symptom, every safety question and every extra repair goes to a mechanic.

Write the note, connect the number and agree how the workshop marks jobs done. Spaces paces every message and keeps the number inside safe limits, but no tool can promise WhatsApp will never restrict an account, so keep the agent to customers who message you and customers who expect to hear from you.

Pricing

Plans from $19 a month

Can the agent tell a customer if their car is safe to drive?

No. It should never judge a symptom. It collects the details, offers an inspection slot, sends your urgent-signs wording where it applies and hands the chat to a mechanic.

Can it quote for repairs?

Only for standard work on your price list, such as MOTs, services and tyre fitting. Anything that needs a look at the car is quoted by a mechanic.

How does it know when a car is ready?

Only when your workshop tells it. Agree one simple way to do that, such as a short message from the workshop phone or a shared job sheet, and tell the agent never to say "ready" otherwise.

Can it send MOT reminders?

Yes, as personal messages to customers whose MOT is due, within Spaces' limits. Schedule them for sensible hours and stop for anyone who says they no longer want them.

What about photos of warning lights or damage?

The agent passes them to a mechanic without comment. It should never say what it thinks a warning light means.

Can my mechanics still use WhatsApp on the garage phone?

Yes. The number stays yours and the phone works as normal. When someone takes over a chat, the agent stays out of it until it is handed back.

What if a customer disputes a bill?

The agent should apologise, say a person will look into it and hand the chat over. It should never argue about a bill or agree a discount.

Should the agent say it is an AI?

Many garages do, in the first reply. Customers usually care most about a fast, accurate answer, and knowing a mechanic will join for anything technical.
