A marketplace is a platform where buyers and sellers come together to exchange goods and services. This can occur in physical locations, like local farmers' markets, or online platforms, such as Amazon and eBay. Marketplaces facilitate transactions by providing a space for various products and enabling communication between parties. In a marketplace, sellers list their items, and buyers can browse, compare, and purchase them. Marketplaces often charge fees or commissions for their services, which can include payment processing and customer support. They play a crucial role in the economy by connecting consumers with a wide range of products and services.
