The Online Course in E-Business and E-Commerce focuses on optimising customer relationship management in an online environment by examining e-business and marketplace models, e-business strategies, e-marketing and procurement in some detail. The initial investment for an e-business start-up is generally lower than starting a traditional business, and with technology becoming more advanced and easier to obtain, the barriers to opening a business have been significantly reduced or even removed. Because buyers and sellers can transact at any time and from anywhere, e-business and e-commerce not only provide cost-saving advantages, but also make goods and services accessible on a global scale.
