A marketplace platform is a software system that enables individuals or businesses to create and manage online spaces where users can buy, sell, or rent goods and services. These platforms facilitate transactions between multiple parties, often providing features such as user accounts, payment processing, reviews, and dispute resolution. Examples include e-commerce sites, booking platforms, and peer-to-peer service marketplaces. Marketplace platforms streamline the process of connecting buyers and sellers, ensuring secure transactions and building trust within the online community.
