E-commerce

E-commerce

E-commerce short for electronic commerce is the buying and selling of a product or service by means of the internet. It follows the same basic principles as traditional commerce-that is, buyers and sellers exchange goods for money. There are 4 types of e-commerce which are Product Transactions, Service transactions, auctions, and business-to-business (B2B) transactions.

Advantages:

  • E-commerce offers buyers convenience. It is available 24 hours a day and seven days a week.
  • You can compare prices and make purchases, without having to leave you home or office. In some cases, you can download a product or service such as a music file or computer software over the internet.
  • For sellers, e-commerce is a very good way of starting a business. They do not need a large capital which is the finance. They do not need to build, staff or mantain a store or print  and distribute mail order catalogs.

Disadvantages:

  • E-commerce also has disadvantages, however. For example there is a lack of communication because some people also consider shopping a social experience.
  • Consumers also need to reassure that credit card transactions are secure and that their privacy is respected.
  • Another disadvantage is that some buyers dislike this method of buying a product without touching and feeling it.

Examples of e-commerce web sites are amazon, ebay etc. And an example of a Maltese e-commerce web site is the Airmalta where you can buy your flight ticket online.
