Develop an end-to-end online Booking System application for appointment-based service businesses such as consulting practices, wellness clinics, and personal trainers. Build a clean multi-step client booking wizard allowing visitors to select a service type, choose a specific staff provider, pick an available date on an interactive calendar, and select open time slots generated dynamically based on provider working hours, service duration, and existing reservations. Include custom client intake form fields and integrated Stripe payment processing for collecting deposits or full payments upfront. Automatically send client confirmation emails containing downloadable .ics calendar invitations and booking reference details. Include automated SMS reminder alerts sent prior to scheduled appointments, multi-location timezone handling, and custom refund policy toggles. Provide a powerful Admin Workspace featuring a monthly calendar view, weekly schedule agenda, service price menu manager, staff shift hours editor, custom buffer time settings between appointments, and cancellation management tools that immediately free up calendar slots.
