Oppurtunities
Highly accessible- businesses can operate 24 hours a day, 7days a week, 365 days a year.
Improved information content-in the past customers had to order catalogues or travel to a physical facility before they could compare price and product attributes. Electronic catalogues and web pages present customers with updated information in real time about goods, services and prices.
Challenges
Protecting Consumers-consumers must be protected against unsolicited goods and communication, illegal or harmful goods, insufficient information about goods or their suppliers, invasion of privacy and cyberfraud
Increasing liability- e-Business exposes suppliers to unkown liabilities because internet commerce law is vaguely defined and differs from country to country. The internet and its use in e-business have raised many ethical, social and political issues, such as identify theft and information manipulation
