Why do people miss appointments?
Before you get annoyed at the customer who didn’t turn up, find out what happened. It’s usually one of these:
- They forgot. They booked two weeks ago, and a hundred things happened since.
- They were too shy to cancel. They didn’t want to call and apologise, so they said nothing, and the silence became an empty chair.
- Booking was easy and cancelling was hard. They booked from a link in a second, but cancelling meant a phone call to a busy line.
- Something came up. A sick child, a traffic jam, work that ran over.
You can’t control emergencies. The first three are in your hands, and they make most of the difference.
Make cancelling as easy as booking
It sounds odd, but it’s the basis of everything: a customer who cancels is better than one who doesn’t show up. A cancellation gives you time to fill the slot. A no-show gives you an empty chair.
So, from the moment they book:
- Tell them plainly: “If something comes up, reply to the reminder and we’ll move your appointment.”
- Make changes a single reply in the same chat, not a phone call or another link.
- When someone cancels, thank them. That teaches them cancelling is fine, and next time they cancel instead of disappearing.
Reminders: when and how
Timing: the day before, in the early evening. That’s when people look at their phones and plan the next day. Don’t send in the middle of the night, or early in the morning for an appointment an hour later.
Channel: WhatsApp, because your customers already talk to you there.
Content: just five things:
- The customer’s name.
- The day and time, written clearly: “Tomorrow, Sunday, at 10:30 am”.
- The name of your salon or clinic, and a location link for new customers.
- The staff member or doctor, if the customer chose one.
- How to confirm or change.
Try these and adapt them to your voice:
Clinic: “Good evening Layla. A reminder of your appointment at Dr Sami’s clinic tomorrow, Sunday, at 10:30 am. Will you be coming? If you’d like to change the time, just reply here.”
Barbershop: “Hi Abu Zaid. You’re booked tomorrow at 7 pm with Khaled. Please confirm, and if anything comes up, tell us and we’ll move it.”
Women’s salon: “Good evening Rana. We’re expecting you tomorrow, Thursday, at 4 pm. Can you confirm? If you need another time, just reply.”
A note for clinics: never put medical details in a reminder, neither the diagnosis nor the type of treatment. Someone else in the household may pick up the phone.
No reply to the reminder?
Not every appointment needs the same follow-up:
- A short appointment (a haircut, a quick check-up): if there’s no reply, leave it. The reminder did its job.
- A long or important one (a dental session, bridal make-up, a therapy session): a short call in the morning is worth it. One minute on the phone costs less than two empty hours.
Fill the slot that opens up
A cancellation only helps if someone takes the slot. So:
- Keep a waiting list, even on paper: customers who wanted an earlier time and couldn’t get one.
- When a slot opens, message the first two names on the list: “A slot opened today at 5, would you like it?”
- For barbers and salons: an Instagram story saying “A slot is free today at 5” often brings someone in.
Repeat no-shows: a clear policy, without anger
Some customers miss once; some miss every time. The second kind needs a policy, and the policy has to be known before the no-show, not after.
A simple approach:
- First no-show: a kind message: “We missed you today, hope all is well. Shall we book you a new time?”
- Second no-show: their next appointment is held only once they confirm the reminder.
- Third no-show: they book only same-day free slots, or pay a deposit for long sessions.
Put the policy in one sentence in the booking confirmation, politely. Most customers respect it when it’s clear and the same for everyone.
What to measure
You can’t improve what you don’t count. Each week, look at:
- How many appointments were missed, and how many were cancelled in advance.
- Which days and times have the most no-shows.
- Whether no-shows are higher for appointments booked far ahead (weeks before) or close to the day.
Compare the numbers before and after you start reminders. That shows you what actually works for you, not just what we say.
If you want reminders to go out on their own
All of the above can be done by hand, but someone has to remember to send every day, follow the replies and move appointments. Mirsal does that on WhatsApp from your business number: it sends a reminder before the appointment to customers who agreed to receive one, the customer confirms in one tap, and every appointment sits in the Tfaddal calendar. When a customer asks a medical question or has a complaint, the chat goes to your staff.
Questions
When is the best time to send an appointment reminder?
The day before, in the early evening, when people check their phones and plan the next day. Don't send late at night or at dawn.
Should I take a deposit so people don't skip appointments?
Not from everyone. A deposit makes sense for long sessions, or for someone who has missed more than once. What matters most is saying so clearly when they book, not after they miss.
What should a clinic reminder say?
The patient's name, the day and time, the clinic's name and location, and how to confirm or change. No medical details, because someone else in the household may see the phone.
Does Mirsal send reminders from my own number?
Yes, from your own WhatsApp Business number and in your business's name. The customer confirms in one tap, and Meta bills its message fees directly to your account.
