Step-by-Step Guide

6 steps · 15 minutes

1

Enable the waitlist feature

Go to Settings > Booking Rules and toggle on waitlists for the services you want.

2

Configure waitlist behavior

Set whether clients join the waitlist for a specific date, time range, or any available slot with their preferred provider.

Pro Tip

Allow clients to set a range of acceptable times — it increases fill rates.

3

Set notification preferences

Choose whether waitlisted clients are notified by SMS, email, or both when a spot opens.

4

Define the claim window

Set how long a notified client has to claim the open slot before it goes to the next person in line.

5

Add the waitlist option to your booking page

When a time slot is full, show a 'Join Waitlist' button instead of disabling the slot.

6

Test the waitlist flow

Fill a slot, join the waitlist, cancel the original booking, and verify the waitlisted client is notified.

FAQ

Frequently Asked Questions

How fast are waitlisted clients notified?

Notifications fire within 60 seconds of a cancellation, giving waitlisted clients the best chance to claim the spot.

What if no one on the waitlist claims the slot?

The slot returns to your public booking page as available, so anyone can book it.

Can clients see their position on the waitlist?

Yes. Clients receive a confirmation with their waitlist position and estimated likelihood of getting a spot.

Is there a limit to waitlist size?

No hard limit, but we recommend capping at 5-10 per slot for the best client experience.
