A production-ready platform that gives fleet managers full operational control over vehicles, drivers, trips, expenses, fuel, maintenance, and real-time GPS tracking — from a single unified system built on Laravel.

• Laravel 12 Backend
• Flutter 3.41.6 Driver App Source Code
• Provider State Management
• RESTful Driver API
• Real-Time GPS Tracking
• DVIR Inspections
• Expense Management
• Payroll & Attendance
• Financial Accounts
• Fleet Maintenance
• Offline-Ready Mobile App

Flutter Mobile App Technical Requirements

The included driver application is a complete Flutter project, not a Laravel web wrapper. It was created and tested with Flutter 3.41.6 stable and Dart 3.11.4. Flutter 3.41.6 is the recommended version for reproducing the supplied build. Compatibility with older Flutter or Dart releases is not guaranteed.

• State management: Provider 6.1.5+1 using ChangeNotifier-based feature providers for authentication, trips, GPS tracking, expenses, fuel logs, DVIR, incidents, documents, and app configuration
• Android build environment: Flutter 3.41.6 stable, Dart 3.11.4, Android Studio with Android SDK, JDK 17, and the included Gradle 8.14 wrapper
• iOS build environment: macOS with Flutter 3.41.6, Xcode, CocoaPods, and an Apple developer signing configuration
• Build setup: Run flutter pub get, configure the Laravel API base URL and Google Maps key, then use flutter build apk --release or flutter build appbundle --release. iOS builds require macOS/Xcode.
• Full editable Flutter source is included for Android and iOS; publishing accounts, signing keys, certificates, and store submission are not included.

Important: External GPS and Map Service Costs

Real-time GPS tracking uses the driver’s device location, mobile internet, the self-hosted Laravel server, and Google Maps services. Buyers must provide and configure their own Google Maps Platform account, API key, enabled APIs, and billing account. Google may charge usage-based fees for map display, route, geocoding, or other enabled map services. Mobile data, hosting, SSL, email/SMTP, Apple Developer, and Google Play fees may also apply. None of these third-party services or recurring charges is included in the item purchase price. Pricing, quotas, and free allowances are controlled by the respective providers and can change.

What Is KargoLink and Why Does It Exist?

Fleet operations fail not because of a shortage of vehicles or drivers — they fail because of missing information at the right time. A dispatcher does not know where a vehicle is. A manager cannot confirm whether a driver completed an inspection. Finance has no record of a toll paid in cash. Maintenance is reactive because no one tracked service intervals.

KargoLink is a fleet execution and operations platform designed to close these gaps. It replaces disconnected spreadsheets, WhatsApp messages, and paper logs with a single system that connects every layer of daily fleet operations: trip dispatch, driver activity, vehicle health, operational expenses, and financial accounting.

Built as a web-based admin panel backed by a mobile driver application, KargoLink covers the full operational loop from the moment a trip is booked to the moment it is invoiced, paid, and archived. It is engineered for transport companies, logistics operators, last-mile delivery fleets, and field-service vehicle fleets that need real accountability — not just dashboards.

The Problem KargoLink Solves

• No real-time visibility into where a vehicle is or what status a trip is in
• Drivers submitting cash expenses without receipts or approvals
• Vehicle documents and insurance expiring without advance notice
• No record of pre-trip or post-trip vehicle inspections (DVIR)
• Fuel consumption tracked on paper, if at all
• Maintenance performed reactively after breakdowns, not proactively
• Payroll calculated manually from attendance records kept in notebooks
• No audit trail when a trip changes status or an incident occurs

How KargoLink Addresses Each Gap

• Live GPS tracking submitted by the driver app at regular intervals
• Driver expense submission with receipt photos and admin approval workflow
• Document expiry tracking with centralized reminders report
• Mandatory DVIR checklists enforced before a trip can proceed
• Structured fuel logs with unit conversion, receipt capture, and approval
• Preventive maintenance schedules tracked by both distance and calendar
• Daily attendance matrix with payroll generation tied to payment type
• Immutable status logs and trip timelines for every state change

Admin Panel

Admin Panel: Operational Control Center

The web-based admin panel is the command center for fleet managers, operations supervisors, and finance teams. Every feature is designed around the daily workflows of people who run transport operations, not around generic SaaS conventions.
