What a service reminder program costs a repair shop, and when it pays back

By Steven Von · 2026-10-14 · 4 min read

Text and postcard reminders bring customers back for oil changes and inspections. Here is what each option really costs per month and how many cars cover it.

Most repair shops spend money finding new customers and almost nothing bringing back the ones they already have. A customer who came in for brakes in April is due for an oil change in July, and if nobody reminds them, they pull into whatever quick lube is on the way home.

A service reminder program fixes that. It is not glamorous, and it is usually the cheapest marketing a shop can run. Here is what it costs, broken down by option, and how to tell when it has paid for itself.

What a reminder program actually is

At its simplest: your shop keeps each customer's mileage and last service date, and when something is coming due, they get a message. Oil change, tire rotation, state inspection, brake check, coolant flush, whatever your shop sells on a schedule.

The message can be a text, an email, a postcard, or a mix. The best programs send the reminder, then a follow-up if the customer does not book, then stop.

Option 1: text reminders from your shop software

Many shop management systems include automated texts, or offer them as an add-on. Typical costs:

• Software add-on: often in the range of $50 to $200 a month, depending on the system and how many messages you send.
• Setup time: a few hours to clean up customer phone numbers and set the intervals.
• Ongoing time: close to none once it is running.

Texts are read fast and they are easy to reply to. "Reply YES to book Thursday morning" is about as low friction as marketing gets.

The catch is data quality. If your service writers do not record mileage and mobile numbers on every ticket, the system has nothing to work with. Fix that at the counter first.

Option 2: email reminders

Email is cheaper, often free inside your shop software or a few dollars a month through a basic email tool. Open rates are lower than texts, but email holds more detail: a coupon, a list of what is due, a link to book online.

For most shops, email works best as a companion to texting, not a replacement. Send the text first, use the email for the details.

Option 3: postcards

Postcards cost more per customer. Printing plus postage usually lands somewhere between $0.60 and $1.20 a card depending on size and quantity, and a mailing service adds a fee if you do not handle it in-house.

They also do something texts cannot. A postcard on the fridge sits there for weeks. Older customers and fleet managers often respond better to mail. Some shops send postcards only to customers who have not responded to two texts, which keeps the mail cost low.

When it pays back: a simple example

Here is a hypothetical. Your numbers will differ, so run your own.

Say you have 1,200 active customers and you run text reminders at $150 a month. Each month, about 200 of them are due for something. If 10% of those book because of the reminder who otherwise would have gone elsewhere, that is 20 extra visits.

If your average reminder visit is an oil change with a $90 ticket, that is $1,800 in work for $150 in cost. If even a few of those visits turn up brakes or tires, the ticket goes far higher.

The break-even is low. At $90 a visit, two extra cars a month cover a $150 text program. Most shops will clear that in the first week.

Postcards change the math, but not by much. Mailing 200 cards at $1 each is $200 a month. At the same 20 extra visits, you are still well ahead.

The calculator lets you put your own car count and average ticket in and see the result.

What makes the difference between a program that works and one that does not

Timing. Send the reminder a week before the due date, not on it. People need time to fit it in.

A clear action. "Your oil change is due. Reply to book" beats "Remember to take care of your vehicle."

Easy booking. If the text leads to a phone line that goes to voicemail at lunch, you lose people. The missed calls guide covers how to cover that gap.

A personal touch. Use the customer's name and their car. "Hi Dana, your 2019 Camry is due for an oil change" reads like it came from a shop that knows them.

How reminders help your Google profile too

A reminder visit is a happy, low-stress visit. That makes it a good time to ask for a review. The median repair shop in our data has 44 reviews, and the top 10% have 343 or more. Returning customers are the easiest reviews you will get. The reviews guide has scripts you can add to the post-visit text.

Where to start this week

1. Check how many of your customer records have a mobile number and current mileage.
2. Ask your shop software provider what their reminder add-on costs and what it sends.
3. Pick one service to start with, usually oil changes.
4. Turn it on for that one service and track bookings for 60 days.

Once it works for one service, add the next. The benchmark report shows how your profile stacks up while you build the program.
