Approval in, lift free.

Many customers are easier to reach on WhatsApp than by phone these days. That’s especially handy for repair approvals: the customer sees photos of the damage, can decide in peace and replies whenever it suits them. To keep it from turning into an argument at pickup, you need a few clear rules.

Repair authorization via WhatsApp: how it works in practice

1. 01Be specific: which work, why it’s needed, estimated amount including tax. A photo of the worn part is more convincing than any explanation.
2. 02Ask for a clear answer: “Yes, go ahead” is better than a thumbs-up. Ask for explicit approval that refers to the amount.
3. 03Agree on a limit: if the effort is still uncertain, name a cap (“up to …”) and promise to check in before exceeding it.
4. 04Confirm in writing: if the approval comes as a voice message or call, sum it up briefly as text and send it back to the customer.
5. 05Keep the chat: don’t delete the conversation, and note the approval with date, time and amount on the repair order.

Hi [name],

During the [inspection/repair] of your [vehicle, license plate], we noticed the following:

– [finding, e.g. front brake pads below wear limit] (photo attached)

Our recommendation: [work]
Estimated cost: [amount] incl. tax
Additional time: approx. [duration], ready for pickup at [time]

Please reply “Yes, approved up to [amount]” or “No, don’t proceed”.
If the cost turns out higher, we’ll contact you first.

Best regards,
[shop]

Document approvals properly

An approval is only useful if you can find it later. A fixed note on the repair order works well: “Approved via WhatsApp, [date, time], up to [amount], customer [name]”. Add the chat history on the shop phone or a screenshot in the job file. That way, the colleague at the front desk also knows what was agreed when the customer picks up the car.

Turn vague problem descriptions into clear info

“Something’s rattling” is where every diagnosis starts, but not where it ends. Ask the right questions when booking the appointment and you’ll save test drives and callbacks. Send these questions to customers or save them as a quick reply in WhatsApp Business:

To help us find the problem quickly, please describe it briefly – a voice message is fine:

1. What exactly happens? (noise, vibration, warning light, smell, loss of power)
2. Roughly where? (front/rear, left/right, engine bay, interior)
3. When? (on a cold start, when braking, in turns, above a certain speed)
4. Since when – and is it getting worse?
5. Always or only sometimes?
6. Any recent repair, tire change or impact (curb, pothole)?
7. Is a warning light on? A photo of the dashboard helps.

The answers belong on the repair order, not just on the phone. Then the colleague who puts the car on the lift tomorrow morning also knows what to look for – without calling the customer first.

Keep customers in the loop

Many calls to the shop are status checks: “Is my car ready?” If you give a quick update yourself, you get fewer calls and happier customers. Three messages usually do the trick:

1. 01After drop-off: order confirmed, expected to be ready at …
2. 02If anything changes: extra work found or a part arrives later – with a new time and, if needed, a repair approval.
3. 03When it’s done: car is ready, amount, pickup hours, whether the invoice comes in advance.

Do you need a shop app for this?

There’s shop management software with digital vehicle check-in, customer portals and approval links. For some shops that’s worth it. But many customers don’t want to open a link or use a portal – they want to reply quickly on WhatsApp. And your team doesn’t have to learn anything new if you stick with the messenger everyone already has.
