Essentially, ecommerce (or electronic commerce) is the buying and selling of goods (or services) on the internet.
From mobile shopping to online payment encryption and beyond, ecommerce encompasses a wide variety of data, systems, and tools for both online buyers and sellers.
Most businesses with an ecommerce presence use an ecommerce store and/or an ecommerce platform to conduct both online marketing and sales activities and to oversee logistics and fulfillment.
Keep in mind that ecommerce has a few different spelling variations. All of these are synonymous and correct –– their use is largely preference-based.
