Using a waitlist to fill canceled appointments

All Industries · 4 min read

A waitlist lets a client who finds a day fully booked ask to be told when a spot opens, so a cancellation has a chance of being filled instead of sitting empty. It works best when cancellations arrive early, the news reaches waiting clients quickly, and booking the freed time takes a few taps.

Why do canceled slots go unfilled?

When a client cancels, you can often think of someone who'd take the slot. The trouble is reaching them in time. Calling down a list takes minutes you don't have between clients, people don't answer, and by the time someone says yes the appointment may be an hour away. Cancellations that arrive late, or by voicemail after closing, make it harder still.

How does a simple waitlist work?

  1. A client tries to book a day that's full and leaves their name and email to join the waitlist for that day.
  2. Someone with a booking that day cancels, or moves their appointment to a different day.
  3. Everyone waiting for that day gets a message saying a spot has opened, with a link to book.
  4. The first person to book takes the slot.

First come, first served is easy to explain and feels fair. Offering the slot to one person at a time and waiting for each reply is slower, and the appointment can pass while you wait.

Will a freed slot fit the person waiting?

Not always. A canceled 30-minute appointment leaves a 30-minute gap, which won't fit someone waiting for a two-hour color or a full groom. When you set expectations with waiting clients, mention that longer services are harder to fit in at short notice. For those clients, a personal call when a long gap opens, or when two neighboring appointments both cancel, may be the better route.

Get cancellations early enough to refill

A waitlist can only work with the time it's given. A cancellation at 8 a.m. for a 9 a.m. appointment is very hard to fill, while one the day before has a real chance. Three habits help:

  • Give clients a link to cancel themselves, so they tell you when their plans change instead of when your phone line opens.
  • Send a reminder about a day ahead, when many people check whether they can still make it.
  • Set a cancellation window that leaves you time to refill the slot, and explain it on your booking page.

Tell waiting clients what to expect

Joining a waitlist should come with honest expectations. Let people know that a spot isn't guaranteed, that openings go to whoever books first, and that the news will come by email, so they should keep an eye on their inbox. Clients who understand this take it in stride when someone else gets there first.

Keep your own short-notice list too

Some regulars live nearby, work flexible hours or enjoy a last-minute slot. Note who they are in their client record. When a cancellation comes in too close to the appointment for a waitlist email to help, a personal text from you to two or three of them can still fill the gap.

What does the waitlist tell you about demand?

Look over your waitlist every few weeks. If the same days keep filling up and collecting names, that's demand you're turning away. You could add hours on those days, move a staff member's shift, or open earlier. If a day rarely has anyone waiting, there's no case for extending it.

Note which services people were waiting for, too. If most of the names are for one long service that only one person offers, the fix may be training or hiring rather than longer hours.

How the TidyBookings waitlist works

On a TidyBookings booking page, when the day a guest wants is full, they can join the waitlist for that day with their name, email, an optional phone number and a preferred time. When a booking on that day is canceled, or moved to another day, everyone waiting for that day gets an email saying a spot opened, with a link to your booking page. Openings go to whoever books first. Each waitlist entry is emailed once, so a guest who misses out can join again. You can see who's waiting in your dashboard.

You can try the booking flow guests use on the demo booking pages, and how to reduce no-shows covers getting cancellations in early.
