Ecommerce, also known as electronic commerce or internet commerce, refers to the buying and selling of goods or services using the internet, and the transfer of money and data to execute these transactions. It is primarily used to refer to the sale of physical products online, but it can also describe any kind of commercial transaction that is facilitated through the internet. Ecommerce has evolved to make products easier to discover and purchase through online retailers and marketplaces. Independent freelancers, small businesses, and large corporations have all benefited from ecommerce, which enables them to sell their goods and services at a scale that was not possible with traditional offline retail. Global retail ecommerce sales are projected to reach trillions of dollars annually, and it encompasses a wide range of data, systems, and tools for online buyers and sellers, including mobile shopping and online payment encryption. Most businesses with an ecommerce presence use an ecommerce store and/or an ecommerce platform to conduct online marketing and sales activities and to oversee logistics and fulfillment.
