Vehicle Service Management Systems.

I’m building a complete management platform for a mixed vehicle repair workshop and need an experienced developer (or small team) to take it from concept to production. The goal is simple: everything our staff now scribble on paper—job cards, parts used, customer signatures—must live in a single, real-time system that also talks to our customers through both SMS and WhatsApp.

Core workflow
• A vehicle is checked in on a phone or tablet, creating a digital job card that follows it through every bay until final delivery.
• Mechanics update status, add photos and notes, and trigger parts withdrawals as they work.
• Stock levels adjust automatically; low-stock alerts fire and a purchase order can be raised on the spot.
• The moment an estimate is approved, one click turns it into a tax-ready invoice that can be paid online.
• Owners open a dashboard and instantly see today’s revenue, who is the most productive tech, and which services make us money.

Mobile use
All key modules—job cards, repair updates, booking calendar, customer messaging, inventory, invoices and payments—must function smoothly on staff smartphones (Android and iOS). A responsive web portal for desktops is fine for back-office tasks, but the floor runs on phones.

Customer communication
Automated reminders, booking confirmations and repair-status notifications go out via both SMS and WhatsApp, using whichever channel the customer responds to first.

High-level deliverables
1. Database & API architecture that supports multi-device real-time sync.
2. Web admin and mobile (or fully responsive PWA) front-ends for staff.
3. Customer notification engine integrated with SMS and WhatsApp gateways.
4. Inventory module with low-stock rules and purchase-order generation.
5. Estimate-to-invoice flow with payment gateway hookup and basic tax logic.
6. Owner dashboard with daily revenue, productivity and service profitability metrics.
7. Documentation, test data, and hand-over training session.

Acceptance criteria
• Sub-60-second load/login on 4G mobile.
• Offline-first job card edits that sync once connectivity returns.
• 100 % of booking and status alerts delivered via at least one channel (SMS or WhatsApp) and logged.
• All invoices export correctly in standard tax format (PDF + CSV).
• Clear, commented codebase and setup instructions that a new dev can stand up in under an hour.

If you have deployed similar workshop, field-service or inventory systems, show me. I’m happy to discuss stack recommendations as long as they meet the speed, reliability and mobile usability targets above.
