Case Study
Booking & Appointment System Plugin
Replaced a messy booking workflow with a custom WordPress plugin that manages appointments, payments, and schedules all in one place.
Project Brief
The client required an enterprise-grade, end-to-end booking and appointment management plugin tailored for modern multi-location health and wellness clinics.
The project aimed to deliver a cohesive, dual-sided digital solution: a friction-free, 6-step public reservation system designed to maximize client conversion rates, paired with a robust administrative operating console that empowers clinic directors and administrative staff to manage schedules, track revenue, handle intake forms, and optimize daily staff utilization in real time.
The Challenge
The primary operational hurdle was balancing an ultra-intuitive, multi-step booking journey for patients with a highly complex backend scheduling logic.
The system had to support dynamic multi-location management-allowing administrators to seamlessly add, remove, or toggle locations (such as Birmingham, Manchester, London, and Bristol) on and off as business needs evolved. Additionally, the client required full control over practitioner rosters with the ability to dynamically enable, disable, add, or remove practitioners as staffing shifted.
All of this needed to integrate smoothly alongside custom service durations, dynamic add-on calculations, and strict buffer-time rules between sessions to avoid overbooking while maintaining a responsive, low-friction admin UI.

An executive dashboard offering real-time KPI metrics (Total Bookings, Daily Revenue, Staff Utilization percentage), an interactive multi-practitioner daily calendar grid, and searchable booking management tables with status tracking.
Patient Intake & History
Dedicated drawer views displaying full contact history, visit logs, symptom focus areas, and quick actions for rescheduling, processing refunds, or triggering SMS notifications.
Availability Configurator
Granular backend scheduling controls to customize working shifts per staff member, set rest buffers between sessions, enforce minimum advance notice limits, and set maximum booking horizons.
Payment & Communications
Integrated Stripe Payment Intents for secure, SCA-compliant transactions, automated Twilio SMS triggers for confirmations and reminders, and dynamic Add-to-Calendar deep links (.ics generator) for Google Calendar, Outlook Web, and Apple/iCal.
A closer look
Service & Duration Selection
The initial entry point of the booking flow. Patients can filter offerings across clear category tabs (Physiotherapy, Massage, Consultations), compare treatment durations and transparent pricing tiers, and select optional paid enhancements such as Aromatherapy or Extended Cooldowns.
Staff Member & Location
Enables geographic and practitioner routing. Patients select their preferred regional clinic location (Birmingham, Manchester, London, or Bristol) and choose an available specialist based on bio details and star ratings, or select Any Available Practitioner for the fastest booking option.
Interactive Date & Time Picker
Provides an interactive date and time selection interface. Features a full monthly calendar with real-time open date indicators paired with a dynamic grid of available time slots custom-calculated for the selected practitioner's working schedule.
Client Details & Intake Questions
Collects essential patient information and medical context prior to the session. Captures core contact details along with targeted clinical intake questions regarding first-visit status, specific symptom focus areas, and automated SMS reminder preferences.
Payment & Reservation Policy
Secures the reservation with transparent pricing breakdown and direct payment collection via Stripe. Implements inline Strong Customer Authentication (SCA) compliance, dynamic tax calculation, promo code application, and cancellation policy checks.
Booking Confirmation
Delivers a clear post-purchase confirmation screen with a unique booking reference code, key session summaries, and one-click "Add to Calendar" buttons generating direct URLs for Google Calendar and Outlook Web, alongside an auto-generated .ics download for Apple Calendar.
Admin Dashboard & Calendar Overview
The main administrative hub for clinic staff. Features top-level executive KPI cards tracking Total Bookings, Daily Revenue, and Staff Utilization rates alongside a comprehensive side-by-side daily timetable grid across all active practitioners.
Appointment Management & Detail View
A comprehensive operational data table allowing staff to view, filter, and audit all clinic bookings. Incorporates a sliding detail drawer showing historical contact logs, specific patient intake answers, and quick-action buttons to reschedule, issue refunds via Stripe, or send SMS updates.
Service & Staff Availability Configurator
The backend rule engine for managing practitioner schedules. Enables administrators to toggle working days, set custom start/end shift times per staff member, and configure automated logic constraints including rest buffers, minimum notice hours, and maximum advance booking windows.
Architecture
Built as a modular custom WordPress plugin utilizing dedicated REST API endpoints to bypass standard admin-ajax latency. The architecture isolates slot generation into an independent PHP scheduling service, preventing double-booking race conditions during high-volume checkout.
Payment processing is powered by Stripe Payment Intents and webhook event listeners for real-time transactional integrity. Automated post-booking communication is handled by a Twilio SMS API gateway, while dynamic calendar event links (Google Calendar, Outlook Web, Office 365) and auto-generated RFC 5545 .ics file payloads enable immediate one-click calendar additions across all client devices.
Skills Used
This custom booking and management system has completely transformed how our wellness clinics operate across all locations. The public-facing flow makes scheduling completely effortless for our clients, leading to a noticeable drop in booking abandonment. On the management side, the administrative console gives our team full visibility over practitioner schedules, intake histories, and financial metrics in one central place. It has eliminated our scheduling headaches and directly improved our daily clinic utilization.
