Scheduling & Appointments

Automatically fill last-minute cancellations

“When someone cancels 24 hours out, I have to frantically text people to try and fill the spot.”

The short answer

Use the automated waitlist feature in your booking software. When a client cancels, the software immediately emails or texts the people on your waitlist offering them the slot on a first-come, first-served basis. This recovers lost revenue instantly with zero manual effort, keeping your calendar full and your waitlisted clients happy.

How to set it up

  1. Enable waitlists

    Go to your booking software settings and ensure 'Allow clients to join waitlist' is turned on.

  2. Configure the automation

    Set the system to automatically notify waitlisted clients when a spot opens up matching their preferences.

  3. Promote the waitlist

    When you are fully booked, ensure your booking page clearly prompts users to 'Join the Waitlist' rather than just showing no availability.

  4. Let the system work

    When a cancellation happens, do nothing. Let the software send the alerts and fill the gap.

Common questions

What if two people try to claim it?
Modern systems handle this gracefully. The first person gets it, and the second is told the spot was just taken.
