LumenThe Real Cost of No-Shows to Your Business
A no-show isn't just a missed appointment — it's a compounding loss. There's the direct revenue you didn't earn. There's the slot you could have filled with someone else if you'd had 24 hours notice. There's the travel time if you drove to a site visit. And for health practices, there's the compliance requirement to charge cancellation fees that customers resent.
Annual Cost of No-Shows
A physio clinic with 20 appointments per day, a 10% no-show rate, and an average appointment value of $120 loses $48,000/year to no-shows — before accounting for the fact that those slots could have been filled with other patients. Even cutting the no-show rate in half (achievable with automated reminders) recovers $24,000/year. The reminder system costs $500/year to run.
No-show rates in Australian service businesses average 5–15% without reminders. With a well-implemented automated reminder sequence, that drops to 2–5%. For most service businesses, the system pays for itself many times over in the first month.
Why SMS Beats Email for Appointment Reminders
Email open rates in Australia average around 20%. SMS open rates are 98% — and most SMS messages are read within 3 minutes of delivery. For time-sensitive communications like appointment reminders, this difference is decisive.
SMS
98% open rate. Read within 3 minutes. No spam filter. No email app required. Immediate visibility even for customers who don't check email regularly.
20% open rate. Often delayed. Spam filters catch transactional messages. Customers may not check email on the day. Good for confirmations, poor for same-day reminders.
The best approach: use email for confirmations (longer format, includes all booking details and what to bring) and SMS for reminders (short, direct, includes reschedule link). Both channels serve a purpose, but SMS is the one that prevents no-shows.
The 3-Touch Reminder Sequence That Actually Works
This is the sequence used by the highest-performing service businesses across Australia. Three touches, each serving a different purpose:
- ✓ Immediate confirmation: The moment a booking is made — email + SMS with all details, what to have ready, and a calendar link. Makes the appointment feel real and reduces the chance of them forgetting they booked it.
- ✓ 24-hour reminder: SMS the day before. Confirms the time and location. Includes a one-tap reschedule link. This catches the majority of potential no-shows — most people who need to cancel will do so when reminded the day before.
- ✓ 2-hour reminder: SMS the morning of (or 2 hours before an afternoon appointment). Brief and professional. Catches last-minute changes and gives you time to fill the slot if they cancel.
SMS Templates That Work for Australian Businesses
Booking Confirmation SMS
"Hi [Name]! Your booking with [Business] is confirmed for [Day], [Date] at [Time] at [Address]. Questions? Reply here or call [Number]. Need to change? [Reschedule link]"
24-Hour Reminder SMS
"Hi [Name], just a reminder — you're booked in with [Business] tomorrow, [Date] at [Time], [Address]. Need to reschedule? [Link]. Otherwise, see you then!"
2-Hour Day-Of SMS
"Hi [Name], see you in a couple of hours! [Business] — [Time] at [Address]. Need to change plans? [Reschedule link]. Otherwise, we'll see you soon."
Keep every message short. No marketing language. No upsells. Just the information the customer needs and a clear next step. The 98% open rate means these messages are read — don't waste the attention.
