The challenge
Complexity had to become one legible operating loop.
Create a single domain model that keeps bookings, leases, payments, asset status, safety alerts, and owner revenue consistent while giving each role an appropriate operating view.

Operating context
Rental and fleet businesses coordinate customers, vehicles, drivers, owners, payments, maintenance, and live location data—often across separate tools and manual reports.
The system response
The interface and architecture tell the same story.
The system is structured around shared vehicle and transaction records with role-specific customer, driver, owner, and admin surfaces. Booking, payment, return, GPS, loyalty, maintenance, and reconciliation workflows are mapped end to end.

System architecture
From entry point to operating control.
A narrative view of the system boundary. Each layer creates a cleaner handoff into the next and keeps consequential work visible.
01
Role-aware entry points separate customer, driver, owner, and admin work.
02
Bookings and leases reserve the same underlying fleet inventory.
03
Payments reconcile against rentals, deposits, leases, and refunds.
04
GPS events feed alerts and operational status.
05
Reporting views consolidate utilisation, revenue, and exceptions.
