A Car Rental Management System designed to manage all rental operations, vehicle records, customers, payments, and financial transactions in one system. It tracks customers, vehicles, rental contracts, bookings, suppliers, maintenance, expenses, payments, checks, and invoices. The system records every rental transaction with detailed contract information, rental duration, vehicle status, pricing, balances, and payment methods, whether cash or check. It also monitors vehicle availability, maintenance history, insurance, registration, and operational costs across branches or departments — giving a complete view of fleet performance, revenue flow, customer balances, and the financial position of the car rental business.
