Cost and timeline
A simple booking system (calendar, real-time availability, email confirmation and a basic dashboard) usually starts from €3,000-4,000 and takes 4-8 weeks. Cost goes up with integrated online payments, SMS/WhatsApp reminders, recurring bookings, or syncing with external calendars (Google Calendar, Outlook) and other tools you already use (POS, CRM).
We recommend launching first with a single bookable resource type (one room, one professional, one service) and adding complex availability variants (combined resources, group bookings) once the basic flow already works with real customers.
Common mistakes when building a booking system
The most common one is not handling double-booking conflicts properly from the start, which creates empty gaps or overlaps that damage customer trust. The second is not sending automated reminders, which drives up last-minute cancellations and no-shows. The third is building availability as a simple list of fixed time slots instead of a system that handles duration, buffers between appointments and exceptions (holidays, time off), which forces a rebuild of the calendar logic as soon as the business grows.
