Can my time slots start every 15 minutes or half hour?
You can give your clients more freedom in their choice of time. But this also creates a bit messier calendar, and you will be unable to get fully booked all day. By default, time slots depend on the length of your service. So for example a service that is 60 minutes will show time slots at 8.00am, 9.00am, 10.00am etc. But with Step time that service can have time slots starting at 8.00am, 8.15am, 8.30am, etc. You can change how often an appointment can starts by going to Settings > Customize and select Step time. You can choose between 15 and 30 minutes.
