The BLAB Company plan does offer Round Robin booking capabilities.
To set this up all you need to do is the following:
-Set up an appointment or service/product
-Click on the Group widget at the top of your service settings
-Add the team members who you wish to be available for bookings for that service
Please note that a team member must have default availability hours for that booking.
The system will randomly select from all team members who have been added to that appointment/service and who have availability during the booking time.
