The Online Grocery Delivery System is a robust, user-friendly web platform that allows customers to conveniently order groceries online and have them delivered to their doorstep. The system streamlines the entire process from product listing and inventory management to real-time order tracking and secure online payments.

Admins can manage the product inventory, view and update stock levels, manage delivery personnel, and monitor order statuses. End-users can browse grocery categories, add products to a cart, place orders, and track deliveries through a responsive interface.
