1. Confirm every booking in writing
An appointment agreed over the phone is easy to forget or mix up. A written confirmation with the date, time, master, service and address is something the customer can always look back at — and it ends the “I thought it was Thursday” arguments.
2. Remind the day before — and an hour before
Most no-shows aren't deliberate: people simply forget. A short reminder the day before gives them time to reschedule if plans changed, and a second one about an hour before catches those who are running late or about to forget.
Doing this by hand for every customer takes time, which is why it's the first thing worth automating.
3. Make cancelling easy
It sounds backwards, but it works. If cancelling means calling during working hours, many people just don't come. If they can cancel in a couple of taps, they let you know — and you get the slot back while there's still time to fill it.
4. Have a clear policy and say it up front
Decide how much notice you need for a cancellation — say, 12 or 24 hours — and mention it when you confirm the booking. You don't need to be strict with everyone; the point is that customers know the rule before they need it.
For long or expensive services, or for customers who have missed appointments before, it's reasonable to ask for a prepayment or to confirm each booking manually.
5. Fill the slots that free up
A cancelled slot is only lost if nobody takes it. Post today's or tomorrow's free times in your Instagram stories, or send a short message to your regulars — last-minute slots often go to people who were waiting for one.
6. Keep track of who doesn't show up
A customer who misses once is having a bad day. A customer who misses three times is a pattern. Make a note, and for those few, ask for a confirmation or a prepayment before the next booking.
