# Automated service reminders for car dealerships (complete playbook)

> If the customer doesn't get a reminder, the car goes to the local independent instead. Here's how to set up automated SMS and email reminders based on km, date or service contract, and convert 40-60% of them within 30 days.

## Short answer (TL;DR)

Automated service reminders trigger from car km or last-service date, typically 4 weeks before the next interval. SMS with a concrete time suggestion converts 2-3x better than 'book a slot'. Dealers running the flow on CARRUSLiNK report 40-60% booking within 30 days and 20-30% fewer empty workshop slots.

## Why manual reminders fail

- The service advisor calls 30 customers Monday morning, and forgets half of them by Wednesday
- The Excel list is never updated with latest km or last visit
- Email-only customers never reply. SMS gets read within 3 minutes
- The reminder goes out without a concrete time, the customer postpones and forgets
- No link between workshop calendar and reminder, double bookings happen
- When the advisor is out sick, nothing happens for a week

## How to set up the flow in 5 steps

### 1. Define the trigger

Choose whether the reminder fires on km threshold (typically every 15,000-30,000 km) or date (12 months since last service). Use both, whichever hits first wins. Pull km data from the workshop system or DMS.

### 2. Build the SMS template

Specific car ('your Polo AB12345'), concrete time suggestion ('we have a slot April 12 at 9'), one CTA (REPLY YES or link). Sender: a person, not 'noreply'. Max 160 characters.

### 3. Connect to the workshop calendar

The reminder must only propose times that are actually free. CARRUSLiNK pulls the live calendar and proposes 1 concrete slot + a link to 'pick another time'. Never causes double bookings.

### 4. Auto-confirm and book

When the customer replies YES or picks a time, the workshop slot is booked automatically, a confirmation SMS is sent, the customer gets a calendar invite and the advisor sees the booking in their to-do list.

### 5. Measure and iterate

Track: % booked within 7/14/30 days, no-reply rate, no-show rate. Tune time suggestions, lead time (4 vs 6 weeks) and sender name based on data, not gut feel.

## Results you can expect

- **40-60% booking within 30 days** — SMS with concrete time converts 2-3x better than 'book a slot'. Many dealers report 50%+ in month one.
- **20-30% fewer empty workshop slots** — When the flow pushes customers in 4 weeks before the interval, low season fills itself.
- **0 hours of manual work** — The service advisor no longer phones lists every Monday morning. Time spent on upsell and follow-up instead.
- **Fewer customers lost to the local shop** — When the reminder hits before the customer thinks of it, the visit goes to you, not the local Q8 or AutoMester.
- **SMS read 3-5x more than email** — 98% of SMS is read within 3 minutes. Email open-rate in auto sits at 15-25%.
- **GDPR-compliant with consent log** — Every reminder is tied to the customer's consent, and opt-out hides the customer from future flows automatically.

## Frequently asked questions

### How do I set up automated service reminders?

Define a trigger (km threshold or date since last service), write an SMS template with a concrete time suggestion, connect it to the workshop calendar and let the system fire 4 weeks before the next interval. CARRUSLiNK does this out of the box for independent dealers.

### How long before service should the reminder go out?

4 weeks before the next interval is the sweet spot. Earlier and the customer forgets. Later and they've already booked elsewhere. Send a 2nd reminder 7 days before if no reply, typically catches another 15-20%.

### What's better. SMS or email?

SMS clearly beats email in the auto industry. 98% of SMS is read within 3 minutes. Email open-rate is 15-25%. Use email as backup, not as your primary channel.

### What conversion rate can I expect?

40-60% booked within 30 days is normal for dealers using concrete time suggestions and live calendar integration. Dealers that only send a 'book a slot' link sit at 15-25%.

### Does this require workshop system integration?

Yes, if you want to propose concrete times. CARRUSLiNK integrates with most Nordic workshop systems (Autoflex, AutoIT, Workshop Mate and others) or uses its own built-in workshop calendar.

### What about customers without a service contract?

Reminders should go to all customers, whether they have a contract or not. Use the booking as an upsell moment ('we can also write a service contract while you're here'). Conversion from 'car buyer only' to service customer rises 15-25%.
