Why SMS and not email

An auto shop customer does not check email between two jobs or on a work site. They read texts. For an appointment reminder, a vehicle-ready alert or a review request, SMS is the only channel reliably read within the hour.

Text has one more decisive advantage: the reply is instant and fits in a single word. No password, no app to install, no form.

Two-way SMS: the difference that counts

Most tools send. Few listen. Listening is what produces the result.

With Kairos, the customer replies straight to the text they received:

  • YES confirms the appointment.
  • NO cancels it and frees the slot for someone else.
  • RESCHEDULE sends them a link to pick another slot themselves.

The same keywords exist in French (OUI, NON, REPORTER) and Spanish. Customers can also write a free-form message: the text is attached automatically to their job and flagged at the front counter with a red dot, without anyone taking a call.

The concrete effect. A slot cancelled the day before by text can be reassigned. A slot lost because nobody showed up is never recovered. That is where most of the no-show reduction comes from.

The full message cycle

A standalone reminder covers one instant of the customer journey. The Kairos cycle runs from booking through follow-ups, over a period that can reach two years.

  • Booking confirmation: as soon as the online booking is made, with a validation link.
  • Reminder before the appointment: with the option to confirm, cancel or reschedule.
  • Repair status: work progress and estimated completion, including discovered work or a parts delay.
  • Vehicle ready: sent the moment you mark the vehicle as ready.
  • Google review request: after the service, once the customer has actually picked the car up.
  • Social follow-up: a few days later, to widen reputation beyond Google.
  • Service-based follow-up: driven by the maintenance due on that vehicle.
  • Seasonal follow-up: tire changes, winter prep, A/C season.

Timing: where most tools get it wrong

The right message at the wrong moment loses its effect, or annoys the customer. Three rules make a large difference.

The vehicle-ready message follows the shop, not the clock

It does not go out at a fixed pre-scheduled time, but the moment you actually mark the vehicle ready. And it respects an 8 a.m. to 9 p.m. sending window in the shop's local time: a click at 9:30 p.m. pushes the message to the next morning.

The review request waits until the customer has the car back

Asking for a review while the car is still in the shop is the best way to get none. The request goes out about 3 hours after the ready message if that message was sent before 5 p.m., and late the next day otherwise — because customers usually do not come by in the evening, especially in winter. And if you mark the vehicle as picked up, it goes out immediately.

On long jobs, the satisfaction message waits for real completion

In collision, tint or wrap work, the +48 h satisfaction message never fires off the appointment clock: it waits until the vehicle is genuinely ready.

Compliance and anti-spam guardrails

Badly framed texting means opt-outs and, eventually, messages blocked by carriers. Kairos enforces strict rules by default:

  • Consent required: no SMS goes out without collected consent, including for customers imported from another system.
  • Automatic STOP: opt-out is handled at the highest priority and applied immediately.
  • 24 hours minimum between two non-transactional messages to the same number.
  • 8 a.m. – 9 p.m. sending window in the shop's local time.
  • Critical messages first: a marketing follow-up never jumps ahead of an imminent appointment reminder.
  • HELP / INFO: a customer asking for help receives a link to the live status of their repair.

English, French, Spanish

In a Quebec shop, part of the customer base is anglophone. In an Ontario or US shop, part of it is Spanish-speaking. Texting everyone in the same language costs you replies.

Every message goes out in the customer's language — English, French or Spanish, reply keywords included. You manage nothing: the language rides on the customer record.

Expected results and cost

Based on industry benchmarks — roughly a 15% no-show rate in a shop with no reminders — running a two-way SMS cycle corresponds to an estimated 35% reduction in no-shows, about 33% more reviews and interactions, and 18% more retention. These are estimates: your volume and service mix will move them.

On cost, texts are not billed per message: they are included in the per-appointment price, $1.99 for the first 100 appointments in the period and $0.99 after. The impact calculator prices the return at your volume.

Frequently asked questions

How many texts does a customer get per appointment?

It depends on the job. A short service typically produces a confirmation, a reminder, a vehicle-ready message and a review request. A vehicle dropped off for several days also gets repair status messages. A 24-hour minimum between non-transactional messages prevents saturation.

Can customers reply to my texts?

Yes. YES confirms, NO cancels, RESCHEDULE sends a reschedule link. Customers can also write free-form: the text lands automatically on their job and is flagged at the counter. The same keywords exist in French and Spanish.

What happens if a customer replies STOP?

The opt-out is handled at the highest priority and applied immediately. No non-transactional message goes to that number again.

Do texts go out at night?

No. Sending respects an 8 a.m. to 9 p.m. window in the shop's local time. A vehicle marked ready at 9:30 p.m. triggers a message the next morning at 8.

Can I reply to a customer by text myself?

The customer's free-form message is shown read-only on the appointment, with its timestamp, so you can call back or act on it. Replying by SMS from inside Kairos is not open to the shop.
