An e-Commerce website is a content managed website application which allows public to purchase specific products via transactions secured on the vendor's website. Typically, this would involve an administration system which allows the client to manage their inventory, view orders and review transactions within the website database.

Orders are typically processed via secure online Payment Service Providers such as WorldPay, PayPal and SecureTrading or integrated service providers such as Streamline or Realex. Occasionally clients may have in-house card swiping facilities and orders can be relayed directly to their systems.
