The Challenge

WhatsApp and Handwritten Job Cards Running an Entire Garage

A busy automotive garage was managing its entire operation through WhatsApp messages and handwritten job cards. When a vehicle arrived, a paper card was filled in by hand. Technician assignments were communicated via WhatsApp group. Job status updates were WhatsApp messages to whoever needed to know. Invoices were manually typed in Word and emailed — a process that took 20+ minutes per invoice.

The garage owner had no real-time visibility into what jobs were on the floor, which technicians were overloaded, and which vehicles had been sitting too long. Customers had no way to check their vehicle's status without calling the front desk. Service reminders were entirely manual and irregularly sent.

The business needed a professional app that would work for all three stakeholder types: the owner who needed operational dashboards, the technicians who needed job assignment and update tools, and the customers who needed transparent service status without having to call.

The Solution

A Full-Stack Flutter App Running Across Android & iOS

Akshara Technologies built Pro Garage as a production-grade Flutter application deployed to both the Google Play Store and Apple App Store from a single codebase. The app uses Provider for state management, Firebase Firestore for real-time data sync across all three user roles, and Firebase FCM for push notifications.

The job creation flow captures full vehicle details, owner information, reported issues, and intake inspection with photo uploads. Parts and labour are tracked against each job in line-item format. Technicians update job status through a clean mobile interface — from Pending to In Progress to Quality Check to Ready for Collection — with each status change triggering a customer push notification.

Invoice generation is fully automated: when a job is marked complete, the app calculates total parts and labour cost, generates a formatted PDF invoice, and makes it available for customer download. The process that previously took 20 minutes now happens in under 2 minutes. Service reminder notifications fire automatically at configurable intervals post-service completion.
