Retail platforms are online systems that allow businesses to sell products directly to consumers. These platforms provide a marketplace where sellers can list their items, and buyers can browse and purchase them easily. Examples of popular retail platforms include Amazon, eBay, and Etsy. These platforms often offer various tools and services to help sellers manage their inventory, process payments, and handle shipping. They also provide a user-friendly interface for customers, making it simple to search for products, read reviews, and complete transactions securely.
