An e-commerce platform is a digital space where businesses can sell their products or services online. It allows customers to browse items, add them to a virtual shopping cart, and make purchases using various payment methods. Popular examples of e-commerce platforms include Shopify, Amazon, and eBay, which provide tools for managing inventory, processing payments, and handling shipping. These platforms make it easier for both small and large businesses to reach a wider audience without needing a physical store. By using an e-commerce platform, companies can showcase their products to customers around the world, enhancing their sales opportunities and growing their brand presence.
