CentriWebTo reduce appointment no-shows, send a confirmation when the booking is made, a reminder about 48 hours before, and a short text on the day, and make cancelling or rebooking a one-tap job. Add a clear cancellation policy, a deposit for long or high-value appointments, and a waitlist so a cancelled slot gets filled. Keep the reminders purely factual so they stay outside Australia’s rules for marketing messages.
This guide gives you a schedule, message templates, a rebooking path and the rules to follow. It suits clinics, studios, salons, trainers and any local service that runs on bookings.
The short answer
Reminders work, and how you word them matters. The NSW Government’s Behavioural Insights Unit has published its work on hospital appointment reminders. At St Vincent’s Hospital in Sydney in 2016, reminder texts that told patients what a missed appointment cost the hospital ($125) cut no-shows by 19%. In 2019, Central Coast Local Health District sent similar texts seven days and 24 hours before outpatient appointments at Gosford and Wyong hospitals, using the local cost of $215. Missed appointments in those clinics were 33.7% lower than the same months the year before. That second study compared before and after rather than running a randomised trial, so other factors may have played a part, but the direction is clear.
Two lessons carry over to a small business. Send more than one reminder, spaced out. And tell people why turning up, or cancelling early, matters.
Why people miss appointments
Very few no-shows are people deciding not to come. Most fall into a handful of groups:
- They forgot. The booking was made weeks ago and life got in the way.
- Something came up and cancelling felt like more effort than not showing. Calling during business hours, waiting on hold or explaining yourself are all friction.
- They got the time or place wrong. Wrong day, wrong clinic, no idea where to park.
- They didn’t think it mattered. If missing an appointment has no visible cost to anyone, it’s easy to let it slide.
- They’re anxious or unsure about the appointment or the cost.
A good reminder system deals with each of these: it jogs memory, makes cancelling easy, confirms the details and makes the cost of a no-show visible without lecturing anyone.
A reminder schedule: booking, 48 hours, same day
| When | Channel | What it does |
|---|---|---|
| At booking | Email, plus SMS if booked by phone | Confirms date, time, location, practitioner, what to bring, and the cancellation policy |
| 7 days before (bookings made weeks out) | SMS or email | Early nudge, gives time to rebook rather than drop out |
| 48 hours before | SMS | The main reminder, asks them to confirm or reschedule |
| Morning of, or 2 to 3 hours before | SMS | Short, with address and parking |
Adjust to your business. A physio whose patients book a week ahead can skip the seven-day message. A specialist service booked two months out probably needs it. If someone doesn’t reply to the 48-hour reminder, a quick call from reception the next day is worth the effort for long or expensive appointments.
What the message should say (with templates)
Keep reminders short, specific and factual. Include your business name, the date and time, the location, and a simple way to confirm or change. Here are templates you can adapt.
Booking confirmation (email)
“Hi Sam, you’re booked with Alex at Northside Physio on Tuesday 14 May at 10:30am, 12 Smith St, Northside. Please bring any scans or referral letters. Need to change it? Use this link or call 03 9000 0000. We ask for 24 hours’ notice so we can offer the time to someone on our waitlist.”
48-hour reminder (SMS)
“Northside Physio: reminder of your appointment with Alex, Tue 14 May 10:30am. Reply Y to confirm or tap [link] to reschedule. Late cancellations mean someone else misses out on this time.”
Same-day reminder (SMS)
“Northside Physio: see you today at 10:30am, 12 Smith St. Free parking at the rear. Running late or can’t make it? Call 03 9000 0000.”
Notice what’s missing: no special offers, no “book your next massage and save”, no links to a shop. That matters for the rules covered below.
Make cancelling and rebooking easy, and back it with a policy
If the only way to cancel is to phone during business hours, some people will simply not turn up. Give them an easier path and more of them will tell you in time to fill the slot.
- A reschedule link in every reminder that opens your booking page with their details already filled in.
- Reply-to-text handling. If someone replies “can’t make it”, that reply should reach a person or trigger a rebooking message, not disappear into an unmonitored number.
- Rebook in the same message. “No problem, here are three times this week” keeps the patient or client, rather than just recording a cancellation.
- Chase the no-shows kindly. A same-day message (“We missed you today, here’s a link to rebook”) gives people an easy way back before they drift away.
Deposits and cancellation policies
A cancellation policy gives people a reason to tell you early. A deposit gives them a reason to turn up. Neither works if it’s a surprise.
- State the policy at booking, in the confirmation, and again in the 48-hour reminder.
- Keep it simple: for example, 24 hours’ notice to cancel or reschedule, or the deposit is kept.
- Use deposits selectively. They suit long appointments, new clients and high-demand times. They can put off regular clients who’ve never missed a booking.
- Apply it consistently, with discretion. A clear policy that you waive for genuine emergencies feels fair. One applied at random causes complaints.
Health practitioners should also check what their professional body and their registration standards say about fees before charging for missed appointments.
Filling the gap: waitlists and short-notice offers
A cancellation 24 hours out is only a problem if the slot stays empty. A waitlist turns it into an opportunity.
- When someone can’t get the time they want, offer to add them to a waitlist and ask if they’re happy to be texted when a spot opens.
- When a cancellation comes in, send the slot to the waitlist, first reply wins.
- Confirm the booking straight away and tell everyone else it’s gone.
Your booking software or business automation can run most of this without reception lifting a finger. Keep these messages about the specific time they asked for. A text that offers a discount to fill the gap is a promotion, and the marketing rules apply.
The rules: reminders vs marketing messages
In Australia, marketing texts and emails fall under the Spam Act, enforced by the Australian Communications and Media Authority (ACMA). ACMA’s guidance is that messages containing only factual information, plus your business name, logo and contact details, don’t need consent or an unsubscribe. A plain appointment reminder fits that description.
The trap is adding promotion. ACMA warns that a mostly factual message that also includes promotional content, or links to it, is treated as a commercial message. Then you need consent, clear identification and a working unsubscribe. The simplest approach is to keep reminders and promotions completely separate. Our guide to the rules for SMS marketing covers the detail.
Health businesses have extra privacy obligations around how patient information is used. Our guide to patient recall and reactivation covers those. This is general information, not legal advice.
Where to start
- Pull last quarter’s no-show and late cancellation numbers so you have a baseline.
- Write your cancellation policy in one or two sentences.
- Set up the confirmation, 48-hour and same-day messages using the templates above.
- Add a reschedule link and make sure text replies reach a person.
- Start a waitlist and send cancelled slots to it automatically.
- Compare your no-show rate after three months.
Most booking systems can do some of this, and a connected CRM can do the rest. If you run a clinic or studio in health and fitness or a booking-based business in local services, we can set up the reminders, rebooking and waitlist so they run on their own.
