The waitlist feature has been released and is available under the main Clients menu. The Waitlist allows users to add clients who are waiting for an appointment and has functionality to record their available days and times, their preferred diary, custom notes as well as a location.
To add a client to the wait list simply go to People > Waitlist and then click "Add To Waitlist".
You are able to drag and drop clients in the waitlist to order them based on priority, or time spent on the wait list. By default, any new client added to the waitlist will be added to the bottom of the list.
