An ecommerce store is an online store that allows businesses to sell products or services over the internet to customers. Ecommerce, short for electronic commerce, is the buying and selling of goods or services online. It involves conducting commercial transactions through websites, mobile apps, or other online marketplaces. Ecommerce enables businesses to reach a global audience, streamline operations, and provide customers with convenient online shopping experiences. Ecommerce businesses can range from small, home-based operations to large, multi-million dollar enterprises. There are three areas of ecommerce: online retailing, electronic markets, and online auctions. Examples of ecommerce include B2C websites that sell goods and services to consumers, such as clothing retailers, electronics stores, and grocery stores. Ecommerce platforms include online marketplaces such as Amazon and eBay, software as a service (SaaS) tools that allow customers to "rent" online store infrastructures, or open source tools that companies manage using their in-house developers.
