Features
System Focus AreasA scalable conversion engine.
Book Catalog & Browsing
The platform provides a structured catalog system where users can browse books by categories, genres, authors, or price range. Each book has a dedicated product page containing detailed descriptions, pricing, availability status, and cover images. Search and filtering functionalities enhance discoverability and improve user experience.
User Account Management
Users can register and log in securely, manage personal details, view order history, track order status, and save favorite books. This improves personalization and encourages repeat purchases.
Shopping Cart & Checkout System
Customers can add books to their cart, update quantities, and proceed to a secure checkout process. The checkout includes address management, order summary, coupon code application, and secure payment processing.
Admin Panel
The platform includes a comprehensive admin dashboard where administrators can add, edit, or delete books, manage inventory, track sales and revenue, create and manage coupons, and monitor user activity. This ensures full control over operations and promotions.
Coupon & Discount Functionality
One of the core features of the platform is its flexible Coupon & Discount system. The system allows administrators to create and manage percentage-based discounts, fixed-amount discounts, limited-time promotional codes, usage-restricted coupons, and minimum purchase requirement coupons.
During checkout, users can apply valid coupon codes to receive instant discounts. The system validates coupon eligibility in real time and recalculates the total order amount automatically.
