Our company is interested in using the tool for internal services offered (nail salon, hair salon, massages) but, we need waitlist capability.
It could be as simple as a waitlist by service offered and/or a waitlist by staff member. It wouldn't need to move people into an open slot just keep a list of customers that want to be on a waitlist.
The customer could choose a specific service, staff member and date/date range and that information would be saved and available to a staff member or members.
