A missed appointment isn't just an inconvenience — it's a bay standing empty, a mechanic with no work, and revenue you'll never recover. For most repair shops, a 15–20% no-show rate is "normal." It doesn't have to be.
The simplest fix is one most workshops overlook entirely: automated appointment reminders.
Why Customers Miss Appointments (It's Not What You Think)
When you ask customers why they missed their appointment, the answer is almost never "I didn't want to come." It's:
- "I forgot it was today."
- "I lost your number and couldn't call to reschedule."
- "Something came up but I didn't know how to cancel."
These are all solvable with a single automated message sent at the right time.
The Timing That Works
Research across service industries consistently shows that two reminders produce the best results:
- 24 hours before: Gives the customer time to reschedule if needed
- 2–3 hours before: A final nudge on the morning of the appointment
The 24-hour reminder is the more important one — it prompts customers to either confirm or contact you to reschedule, giving you time to fill the slot. The morning reminder catches the customers who genuinely forgot.
What Should the Reminder Say?
The best reminder messages are short, clear, and contain exactly the information the customer needs:
- Their name and your workshop name
- The date and time of the appointment
- What service is scheduled
- A contact number or way to reschedule
Avoid lengthy marketing text in reminders. The goal is confirmation, not a newsletter.
SMS vs. Email: Which Works Better?
SMS open rates are around 98% — email is closer to 20–30%. For time-sensitive reminders, SMS is significantly more effective. However, email is valuable for the 24-hour reminder when you want to include more detail (service description, preparation notes, directions).
The best approach: send an email reminder 24 hours before, and an SMS reminder 2 hours before. If you can only do one, choose SMS.
Handling Cancellations Without the Phone Tag
A reminder that includes a simple "reply to reschedule" option eliminates the phone-tag problem. When a customer can reschedule with one message instead of calling during workshop hours, more of them will — and you get the cancellation with enough time to fill the slot.
"We went from 3–4 no-shows a week down to about one. The reminders basically pay for themselves — that's 2–3 extra jobs a week we keep instead of lose." — Workshop Owner
Setting Up Appointment Reminders in Garage Manager
With Garage Manager, appointment reminders are configured once and then run automatically:
- Go to Appointment Settings
- Enable email and/or SMS reminders
- Set your timing (24 hours, 2 hours, or both)
- Customise the message template with your workshop name and details
Every appointment created after that will trigger reminders automatically — no manual action needed per appointment.
The reminder feature is part of the paid plan, which starts from €9.90/month. When you consider that one recovered appointment per week more than covers that cost, it's straightforward maths.
