Booking times for online booking can currently be controlled using the booking rules — for example with a 30-minute grid, which only offers customers full or half hour appointments. In addition, the Phorest booking logic, which is designed to avoid gaps in the calendar, applies. Time slots are also suggested directly following existing appointments, even if they do not exactly match the 30-minute rule. This logic ensures that there is no unnecessary idle time — for example when one appointment ends at 10:20 and the next doesn't start until 10:30am. You cannot disable this behavior with the current settings. However, the “Masterclass by Hasan Aslan — 86758” salon wishes to be able to activate or deactivate this function independently. Personally, I find automatic optimization useful because it makes workload more efficient.
