Many small business owners only realise they do not fully control their website when something goes wrong. A developer disappears, an agency relationship turns sour, a domain renewal is missed, or the hosting account turns out to be registered under someone else's name. Suddenly, the business owner cannot access the website, cannot move it, cannot update it, and sometimes cannot even prove full control without a long recovery process.

E-commerce is often described simply as buying and selling online, but that definition is too narrow. In reality, electronic commerce covers a much wider business landscape. It includes online transactions, digital payments, electronic product catalogues, customer support, business-to-business document exchange, internal workflow automation, online marketplaces, digital marketing, and the technology infrastructure that makes all of these activities possible. The course material frames e-commerce as a combination of business strategy, communication networks, data management, security, and electronic business processes.
