Multi-tenant CRM &
cross-platform mobile app for car wash businesses

We delivered a multi-tenant CRM system that centralizes booking, employee management, and finances for car wash businesses. Alongside it, we built a cross-platform mobile app integrated via REST APIs, enabling users to find nearby locations on a map, check availability, and book service slots in real time.

Challenge

RocketWash was looking for a reliable engineering partner to design and develop a multi-tenant CRM alongside a cross-platform mobile app. Leveraging our deep background in building CRM solutions for the automotive domain, we stepped in to build the technical foundation and deliver the core product capabilities.

Product goals

Enable fast customer booking flow
Improve operational control over employees and reduce revenue leakage
Centralize business data for real-time visibility into orders, revenue, and workload
Ensure reliable SMS notifications for bookings and schedule updates
Support scalable system architecture for multi-location car wash businesses

Solutions

We developed a multi-tenant CRM platform that automates workflows for car wash businesses. To minimize administrative overhead, we optimized the intake process by automating pricing calculations and implementing a rapid customer search that logs new bookings in seconds.

Alongside the CRM, we built a cross-platform mobile application for car owners. Connected via REST APIs, the app allows users to locate facilities on an interactive map and book appointments instantly. The system also integrates localized SMS gateways and features AI-powered license plate recognition via video surveillance.

Engineering approach

We built the backend on Ruby on Rails with PostgreSQL to handle complex operational workflows within a secure, multi-tenant environment. To guarantee non-blocking execution under heavy loads, core components were decoupled into Sidekiq background workers backed by Redis. The application layer is served via Puma behind NGINX, establishing a highly scalable production environment.

For search-intensive scenarios, we integrated Elasticsearch to achieve low-latency querying across large datasets. To ensure isolation at the organizational level, we leveraged a schema-based multitenancy model that segregates data between independent car wash businesses while maintaining a single, unified codebase.

On the frontend, we developed a React Native mobile application that communicates with the CRM backend via REST APIs. The app integrates native map services to geolocate nearby facilities.
