     A History of E-commerce
• Electronic Data Interchange – the exchange,
  using digital media, of standardized
  business documents such as purchase orders
  and invoices between buyers and sellers
• Financial EDI – an aspect of the electronic
  payment mechanism involving transfer of
  funds from the bank of a buyer to a seller
            Level of E-commerce
              Sophistications
Level        Characteristics
Primitive    Static web pages or ‘brochurweare’
             Searchable site with dynamic pages such as online catalogue
             Integration with operational databases, e.g. inventory searching,
             package tracking, job posting
             Customer transaction through the Internet, e.g. selling products
             and services, buying and selling shares, applying for loans
Advanced     Full electronic commerce (i.e. integrated fulfillment cycle of
             ordering, shipping, billing)
   Reasons for the Growth in E-
            commerce
• Increase in demand for choice (product depth,
  global reach, price choices)
• Demand for information (detailed product
  information, inventory, inventory, order status)
• Demand for interactive, online support
• Avoidance of travel and parking difficulties for
  consumer e-commerce
• Elimination of time constraints (that is, opening
  hours or delays between placing an order and
  delivery)
       Benefits of E-commerce
• Lower purchasing overhead – especially for small
  value and repeat orders
• Greater choice (greater product depth and global
  reach)
• Faster fulfilling cycle time (ordering, shipping,
  billing)
• Greater ability to supply information (inventory,
  order status, etc.)
• Lower cost than EDI
• Ease of swapping between suppliers greater than
  with EDI
           Benefits for suppliers
• A global reach, leading to more orders
• Reduced administration overhead (paperwork automation
  leading to a lower cost for each order made)
• Reduced asset requirement (physical properties for
  companies with a retail network)
• Integration between back office and online ‘shopping’
  activities
• Integration of online ‘shopping’ activities with database
  marketing
• Less need for distribution via channel (disinter mediation)
• Reduced working capital (inventory)

  access
• Development of ‘off the shelf’ e-commerce
  products

• Poor performance leading to slow download
• Inertia of habitual conventional shopping and
  purchasing
• Internet access still limited

   – Non-banks do not report to central bank which leads to
     uncertainty and instability in the money supply
• Tariffs and taxation
   – Value added Tax charged depending on location of
     supplier and consumer
