If you run a business that relies on client appointments, you know how much effort it takes to plan and manage the calendar. Clients, customers, or patients contact you asking for an appointment, and you have to figure out when it can work. It only gets more complicated when you have to slot in emergency bookings, reschedule someone on short notice, or cut your losses for no-shows. There's no need to do this work manually, however, because appointment scheduling apps can do it for you, and they can do it with greater ease and fewer headaches.
