SellPoint

Project Domain / Category

Web Application

Abstract / Introduction

The SellPoint is a comprehensive web-based application that enables multiple vendors to register, list their products, and sell them to customers through a unified platform. Unlike traditional single-store e-commerce systems, this platform allows vendors to create and manage their own online stores within the application. Customers can register on the website, browse products from various vendors, add them to their shopping cart, and complete purchases using different payment methods.

The system includes an admin panel for managing vendors, products, and customer activities, as well as vendor dashboards for managing orders, products, and revenue. The goal of this project is to streamline the online buying and selling process, empower small businesses to sell their products online, and provide customers with a centralized marketplace experience similar to Amazon or Daraz.
