E-business models

A business model outlines how certain objectives are achieved, such as:

  • Presence of business
  • Revenue strategy
  • Pricing strategy
  • Value proposition
  • Competition

Presence of business

We categorize the presence based on the level of physical / virtual presence.

  • Brick and mortar (offline)
  • Click and Brick (hybrid)
  • Click only (online)

Revenue strategy

Where does the revenue come from?

  • Subscription
  • Transactional
  • Traditional sales
  • Affiliate marketing (profit from referrals)

Pricing strategy

How are the products priced?

  • Versioning - Multiple versions (e.g. professional, student)
  • Bundling - Cheaper at bulk
  • Freemium - Basic free, premium paid
  • Free trial - Limited time test before purchase

Long tail strategy

  • Profit from selling many low-volume, unique items rather than few high-volume items
  • Particularly effective in e-commerce where:
    • No physical inventory limitations
    • Items easily discoverable online
    • Helps compete in crowded markets

Product differentiation

  • Vertical - By Standards
  • Horizontal - By Tastes

Porter's Five Forces of Competition

  1. Rivalry among existing firms (no. of competitors \uparrow     \implies competition \uparrow)
  2. Threat of new entrants (entry barriers \uparrow     \implies competition \downarrow)
  3. Bargaining power of suppliers (no. of suppliers \uparrow     \implies dependency \downarrow)
  4. Bargaining power of buyers (supply \uparrow power of buyers \uparrow)
  5. Threat of substitutes (no. of alternatives \uparrow     \implies competition \uparrow)
