1.Worldwide Presence: This is the biggest advantage of conducting business online. A firm engaging in e-business can have a nationwide or a worldwide presence. IBM was one of the first companies to use the term e-business to refer to servicing customers and collaborating with business partners from all over the world. Dell Inc. too had a flourishing business selling PCs throughout the US, only via telephone and the Internet till the year 2007. Amazon.com is another success story that helps people buy internationally from third parties
Disadvantage of online business
Sectoral Limitations: The main disadvantage of e-business is the lack of growth in some sectors on account of product or sector limitations. The food sector has not benefited in terms of growth of sales and consequent revenue generation because of a number of practical reasons like food products being perishable items. Consumers do not look for food products on the Internet since they prefer going to the supermarket to buy the necessary items as and when the need arises.
