E-commerce companies make money through various revenue streams. The primary source is the sale of products or services on their online platforms, where customers make purchases and transactions are facilitated electronically. Additionally, e-commerce companies often generate revenue through subscription models, where customers pay for premium features or services. Advertising and partnerships with other businesses, where companies pay for visibility on the e-commerce platform, contribute to revenue. Some e-commerce entities also earn through fulfillment services, charging fees to third-party sellers for warehousing, packaging, and shipping. The diversity of these revenue streams allows e-commerce companies to create a sustainable and profitable business model in the digital marketplace.
