A marketplace is a multifunctional online platform that acts as an intermediary between sellers (individuals or professionals) and buyers, offering them a shared sales space. More than just an e-commerce site, a marketplace enables multiple sellers to display their products or services on a single interface to attract a wide audience. It acts as an online transaction engine, simplifying the buying and selling experience for users while managing the technical, logistical and sometimes marketing aspects.
01. What is a Marketplace?
Une marketplace est un site de commerce en ligne multi-vendeurs qui offre aux vendeurs un espace pour proposer des produits ou services à un grand nombre d’acheteurs potentiels.
Unlike a conventional e-commerce site that sells its own products, a marketplace hosts and coordinates sales by third parties, making available to them an audience already present on its platform.

02. How does a Marketplace work?
Marketplaces use a commission model: they take a percentage of each sale made via their platform, as well as any additional fees, such as subscriptions or management fees. Sellers manage inventory, packaging, shipping and customer service themselves, while the marketplace provides the platform, marketing and payment infrastructure.
