An ecommerce website is a website that allows people to buy and sell physical goods, services, and digital products over the internet rather than at a brick-and-mortar location. Ecommerce transactions typically involve electronically transferring funds and data between two or more parties. Ecommerce websites enable businesses to process orders, accept payments, manage shipping and logistics, and provide customer service. Ecommerce has become an important tool for small and large businesses worldwide, not only to sell to customers, but also to engage them. Ecommerce platforms and vendors include online marketplaces such as Amazon and eBay, software as a service (SaaS) tools, and open source tools. Ecommerce can take on a variety of forms involving different transactional relationships, including online retail sales of physical or digital goods, wholesale transactions, dropshipping, crowdfunding, subscription-based products and services, and services and software.
