The biggest disadvantages of e-business is its inherent separation from the customer. The customer and the product come face to face in a traditional brick and mortar business. The faceless nature of an e-business causes an issue of trust, which remains hard to resolve.
Another big disadvantages of e-business is its unsuitability in many areas or sectors. E-business, for instance, cannot treat a patient.
The success of an e-business depends on robust computer systems, updating and maintaining the website, security of e-commerce transactions, reliability of shipping and delivery, and search engine optimization. Managing such critical components seem easy, but in most cases, such components remain far unstable and unreliable than the critical components of a traditional brick and mortar business. Search engine optimization and other technological components remain in a constant change of flux, with new standards replacing old standards by the day. This requires the entrepreneur to spend considerable time and resources in keeping up with the developments.
A far bigger threat is the danger from viruses, Trojans, worms, and other malware. An e-business need to invest heavily on SSL certification, antivirus, and other security mechanisms, and even then, the business and its customers remain at risk of various attacks and scams.
Finally, success of an e-business depends largely on the success of the delivery channel partner. Only those e-businesses that can ensure delivery of the product to the customer in a timely and safe manner can survive. Most e-businesses remain at the mercy of third party shipping vendors in this regard.
Many people weighing the advantages and disadvantages of an e-business remain comfortable carrying out business the traditional way, that is, in person or face-to-face, and seeing the product before purchasing. The fact that an online entrepreneur may display one thing and ship another thing, the security risks associated with financial transactions over the Internet, possible misuse of private data either by the e-business or some hackers, and other threats make many people unwilling to opt for e-business and continue to patronize the traditional brick and mortar business.
