PARK & WASH
PROJECT BRIEFING:
The client required a sophisticated, user-friendly platform to manage a mobile car wash service called Park&Wash.
The service is to be rolled out across the USA and operated across various shopping centres.
The system needed to support three user groups:
- Administrators
- Customers
- Agents/Washers.
Each user type has its distinct workflows and access levels. The platform also had to support flexible appointment scheduling, QR code integration, SMS communication, and a seamless booking-to-payment experience using Square.
The project’s core goal was to provide a contactless, eco-friendly car wash experience booked directly via QR code or a web interface.
Park&Wash emphasised critical requirements being:
- Mobile responsiveness
- Automated customer
- Washer notifications
Also, dynamic booking logic is tailored to vehicle type, location, and real-time availability.
WHAT WE DID:
Developed a Modular Admin System
Built on a PHP/Linux-hosted environment, the admin dashboard includes tools for managing washers, cities, shopping centres, vehicle types, customers, and bookings. Features include:
-
- Assigning agents/washers to one or multiple centres
- Calendar-based availability settings
- QR code generation for each shopping centre
- SMS template management
- Vehicle and pricing configuration
- Customer repeat booking detection based on license plate or mobile number
Created a Smart Booking Workflow
Logic Replace designed a responsive customer booking flow that is accessible via city-based selection or QR code. Core features:
- Step-by-step booking with options to select city, shopping centre, vehicle type, make, and colour
- “Wash Now” logic: if the next available slot is within 5 minutes, display immediate booking
- Dynamic appointment durations by vehicle type (car, SUV, van/truck) and editable by the admin
- Pre-filled returning customer info based on license plate
- SMS confirmation with estimated wash completion time
- Secure payment pre-authorisation via Square; the charge is only finalised upon service confirmation.
Washer Web App Development
A lightweight mobile web app allows washers to:
- Log in and receive real-time booking alerts
- View detailed vehicle info and parking location
- Trigger one of three completion statuses:
- All Clean (triggers SMS and confirms payment)
- Unable to locate (triggers SMS, cancels charge)
- Vehicle Too Dirty (triggers SMS, cancels charge)
- Notifications are sent only to washers assigned to that period and centre
- Cancelled appointments immediately reopen the time slot for new bookings
Built a Feedback Loop
Integrated post-wash feedback collection via SMS with a 5-star review and comments form. All reviews are stored within the system for future reporting and customer tracking.
Tested Across All Interfaces
Used BrowserStack to perform multi-device and multi-browser testing on the customer site, the washer app, and the admin dashboard to ensure seamless operation.
Sales Report
The admin interface includes a dedicated Sales Report section designed to help the business monitor performance and make data-driven decisions. It consists of:
- Overall Report
A weekly performance table aggregating data across all shopping centers, with a 12-week historical view of key metrics. - By Site Report
Individual weekly sales reports for each shopping center, also tracking 12 weeks of history to identify trends and performance variances by location. - By Agent Report
A performance table showing weekly sales figures by washer/agent, with an 8-week history, ideal for staff evaluation and incentive tracking.
Each report provides a clear and easy-to-interpret layout to support management in evaluating trends, setting goals, and optimizing resources.
All looks great. Thanks for all the work and video user guides.
