MarketHub serves as a digital hub for seamless online shopping and selling. On this platform, sellers and buyers are required to set up their profiles. They are required to provide their full names, email addresses and phone numbers. For sellers, product listings contain essential details, such as product name, price and description. To make it easy for buyers to search for a product, the seller needs to specify a category for the product, such as homeware, clothing or sports. Buyers can initiate purchases by placing orders for desired products, and the purchase of each product is considered a separate order. The price of each order is captured for clear and easy payment handling.
