WhatsApp and SMS appointment reminders for your repair shop, plus refill when it falls through anyway
An automatic appointment reminder by WhatsApp or SMS brings forgotten garage appointments back before the lift stands empty. And if a customer still does not show up, TerminJet refills the open slot automatically from your waitlist, instead of simply writing it off.

Garage appointment reminders cut no-shows, refill saves the rest
Reminders prevent most of the drop-offs. But not all of them. TerminJet covers both sides: prevent and refill.
- up to 50%
- fewer no-shows with an automatic reminder up front
- 5-15%
- typical drop-off and no-show rate at repair shops without reminders
- < 60 sec.
- from the cancelled appointment to the replacement offer sent to the waitlist
- 0
- calls needed to fill a free lift again
From booking to a saved lift, automatically
- Schritt 01
Appointment booked, reminder scheduled
As soon as a tyre change, a service or an inspection appointment is booked, TerminJet schedules the reminder. Customers choose at booking whether they want to be reminded by WhatsApp or SMS, with documented consent.
- Schritt 02
The reminder goes where it gets read
One to two days before, the reminder arrives with date, time, service type and drop-off time. Customers can confirm, reschedule or cancel straight from the message, without calling.
- Schritt 03
Rescheduled instead of forgotten
Anyone who cannot make it reschedules the garage appointment themselves within your rules. The original slot frees up immediately and becomes refillable, instead of sitting empty on the day.
- Schritt 04
Fell through? The slot gets refilled
If someone does not show despite the reminder or cancels at short notice, the engine starts the refill: it offers the open slot to the right person from your waitlist by WhatsApp or SMS.
Garage appointment reminders cut no-shows, but the empty slot stays the problem
Most tools can remind you, and then that is it. If a customer cancels after the reminder, the lift still stays empty. TerminJet goes one step further: the cancelled appointment automatically triggers a replacement offer to your waitlist, so the gap turns back into a paid job.

The 9 a.m. tyre change cancels in the morning
The same event, two worlds. On the left today's effort, on the right with TerminJet.
- The customer forgot the appointment and does not get in touch at all.
- The lift stands empty at 9 a.m., the mechanic waits for work.
- Nobody at the front desk has time to call the waitlist.
- The slot lapses, in peak season hard cash that does not come back.
- The customer got a WhatsApp reminder the day before and comes, or reschedules early enough themselves.
- If they do reschedule at short notice, the 9 a.m. slot is marked free immediately.
- The engine offers it to the right person from the waitlist by WhatsApp.
- If they reply yes, the lift is booked again, without a single call.
Features that fit the repair shop
Reminders by WhatsApp and SMS
Automatic appointment reminders over the channel your customers actually read. We set the timing, text and channel to your business, from the tyre change to the inspection.
Confirm, reschedule, cancel in chat
Customers respond straight from the reminder. Whoever reschedules stays in the system; whoever cancels frees up the slot, instead of simply not showing up.
Automatic refill
If an appointment falls through despite the reminder, the engine offers the open slot to the right person from your waitlist, in under a minute instead of after closing time.
Vehicle data on hand in advance
Number plate, model and service request come in already at booking. The reminder includes the drop-off time, so the morning intake does not jam up.
Seasonal capacity for tyre changes
Open up more slots for the peak on purpose and throttle them back afterwards. Reminders and refill scale with you, without rebuilding the calendar.
Documented consent
Messages only go to contacts with documented consent. Hosting in the EU with Hetzner, AES-256 encryption, set up GDPR-aware.
Common questions about appointment reminders
Are the reminders sent by WhatsApp or by SMS?
Both are possible. You set the preferred channel, and customers can choose at booking. WhatsApp is usually read fastest, SMS reaches everyone, even without an app.
By how much do reminders lower the no-show rate?
In our experience automatic reminders cut drop-offs noticeably, in many businesses by up to 50 percent. How much it is for you depends on your customers and appointment types, and we work that out against your numbers in the free audit.
What happens if a customer does not come despite the reminder?
Then the refill starts. The open slot is offered to the right person from your waitlist by WhatsApp or SMS. If nobody responds, the offer expires and the next person moves up, with no call from your team.
Can customers reschedule straight from the reminder?
Yes. From the message they can confirm, reschedule or cancel, within the deadlines and rules you set. Slots that free up are immediately refillable again.
Is this compatible with GDPR?
Messages only go to contacts with documented consent. TerminJet runs on your own domain, is hosted in the EU with Hetzner and encrypts personal data with AES-256. We set it up GDPR-aware for you.
Do we have to set this up ourselves?
No. We are a digital agency in Germany and set up the reminder logic, channels, waitlist and the website integration for you, and we look after the system on an ongoing basis.
