A list of people on a wait list are those who are awaiting a service that is not yet available. Those in order of placement on the wait list are often granted access when the desired opportunity becomes available.
The wait list option must be enabled before you can use this feature. In order to enable this:
Go to the "Setup".
Click on the "Booking settings".
Click on the "Booking Option".
Click "Save" after enabling the "Wait list" option as indicated below.
If the calendar is fully booked for the entire day, you can still manage clients using the waitlist feature effectively. Customers can choose to confirm their appointment, enter their details, and join the wait list.
When the appointment is confirmed, it will appear in the "Wait list" under "Home".
