Also known as: Internet Merchant

Definition

An online merchant is a seller that accepts orders through internet-connected channels such as websites, apps, marketplaces, social platforms, or hosted payment pages. The term is broader than a specific e-commerce platform and does not indicate a particular business model, payment method, or company size. An online merchant remains responsible for the commercial offer, customer terms, fulfillment, refunds, and support unless a contract clearly assigns those duties elsewhere.
