Module that is always vigilant and manages the appointments already booked: for example, if there are additional employees, flexi, internship,... it would be ideal for them to redistribute the bookings according to the set competence and availability rules in order to free up space for new customers/services, now this has to be done manually = mapower= expensive. Also watch while booking if you can free up space by regrouping the services, e.g. if you have 3 consecutive zones (15 minutes) free, there is space in that block for 40-minute services, currently the online booking cannot move anything. Even turning on extra hours when there is a lot of demand is not automatically possible, if the HR module knows who wants and can work, even extra hours, the module can first optimize during standard hours but choose to book additional hours from a certain occupancy rate.
