PolishPro β€” A Doorstep Car Wash Platform Built for Real Operational Control

We partnered with PolishPro to turn car washing into a service that comes to the customer instead of the other way around, connecting vehicle owners directly with professional washers nearby. The solution included service-tier booking, real-time washer tracking, eco-friendly service matching, subscription plans, and a live admin system built to support multi-location operations across cities and airports.

About ClientΒ 

PolishPro was built around a simple frustration β€” getting a car washed properly takes time most people don't have, especially with queues and long waits at traditional wash bays. Instead of customers driving to a car wash and waiting, the client's model sends the washer to the car, at home, at work, or at the airport.

The client wanted more than a booking form and a phone number β€” they wanted a complete operational platform. They wanted service-tier selection, live tracking of the washer en route, secure cashless payments, a subscription option for regular customers, and a service that was genuinely eco-friendly rather than eco-branded in name only. To support this vision, the platform also needed an intelligent scheduling system that could assign nearby professionals, optimize travel routes, and minimize service delays.

About Client Gmta

Why did PolishPro Collaborated With GMTA Software?

Car Wash Platform PolishPro

PolishPro had a specific list of requirements that didn't exist in any off-the-shelf car wash booking tool β€” service-tier differentiation, subscription plans with priority booking, a live washer map, and airport location management with scheduled service, all working together on one platform. None of it could be built on a generic template.

They chose us for our experience with on-demand service platforms and for a native development approach β€” Swift and Kotlin β€” built specifically for GPS accuracy in the field. What sealed the engagement was our approach to the admin panel, designed carefully around how their operations team would actually run the business day to day, zone by zone.

Challenges That Shaped the Build

Our Approach

Duration-Aware Booking Engine

Duration-Aware Booking Engine

We treated service type and duration as the core scheduling variable, so a washer already mid-detail is never shown as available, preventing double-booking regardless of how close they are geographically. The scheduling engine continuously tracked active jobs, estimated completion times, and updated technician availability in real time. This allowed new bookings to be assigned only to genuinely available washers with sufficient capacity. The approach improved resource utilization, reduced scheduling conflicts, and ensured customers received accurate appointment windows even during peak demand.

Swift and Kotlin gave us reliable background GPS for washers navigating airports and unfamiliar addresses, with customer notifications tied directly to washer status changes rather than fixed timers. Live location updates allowed customers to monitor progress from dispatch through arrival and job completion. Status events such as en route, arrived, washing started, and service completed triggered notifications instantly. This event-driven approach eliminated inaccurate time-based alerts and improved communication throughout the service lifecycle.

Airport Location Architecture

We built terminal, zone, and bay-level configuration into the admin panel, with photo confirmation tied to bay number at job completion for full accountability. Administrators could define airport layouts and organize service locations with precision. Washers selected the exact terminal and parking bay before starting each job, reducing navigation errors. Completed service photos were automatically tagged with the recorded bay information for verification. This created a clear audit trail for every booking, simplifying dispute resolution and quality assurance.

Subscription & Dispatch Engine

Subscription & Dispatch Engine

Subscriber entitlements are validated at booking and queued with priority, while a Node.js dispatch layer automatically reassigns declined or offline washers without any admin intervention required. Subscription rules are applied instantly to determine customer eligibility and booking benefits. If a washer rejects a request or becomes unavailable, the system immediately identifies the next best available professional. Real-time reassignment prevents delays, maintains service continuity, and minimizes customer wait times.

Process We Followed

01 Research Research
Research

Research

We began by mapping service-tier logic, airport location requirements, and subscription entitlement rules before writing any code to make sure the architecture matched real operational needs from day one. This planning phase defined booking workflows, dispatch logic, user journeys, and operational scenarios, reducing development complexity and ensuring the platform could scale reliably from launch.

  • API contract definition
  • Subscription rules documentation
  • Airport location data mapping
  • Service and duration modelling
02 Design Design
Design

Design

We designed a platform architecture connecting the customer app, washer workflow, and admin panel around one shared booking and dispatch system, built to scale across cities. Every component exchanged data in real time, ensuring consistent booking status, technician availability, and service updates across the platform with centralized synchronization and seamless cross-system communication.

  • Notification and tracking flow design
  • Airport configuration layer design
  • Admin panel and live map design
  • Booking engine architecture
03 Development & Testing Development & Testing
Development & Testing

Development & Testing

Our team built and tested the platform end to end, from booking through dispatch, tracking, and completion, under simulated peak-load conditions across multiple operational zones. We validated system performance, booking accuracy, real-time synchronization, and dispatch reliability to ensure consistent service quality as the platform scaled across cities.

  • Laravel API and Node.js dispatch build
  • iOS and Android app development
  • Load balancer and concurrency testing
  • Airport and subscription flow QA

Business Impact

Subscriber Booking Frequency 3–4x

Subscriber Booking Frequency

Customers on a monthly plan booked three to four times more often than pay-per-use customers during the first two months after launch.

Manual Dispatch Calls 0

Manual Dispatch Calls

Automatic washer reassignment replaced the manual phone calls the client previously relied on whenever a washer declined or missed a job.

Always-On Customer Support 24/7

Always-On Customer Support

In-app support is available around the clock, so customers can get help with a booking, a job in progress, or a subscription at any hour.
