E-business and E-commerce Class 11: Meaning and the Scope of B2B, B2C, Intra-B and C2C

Updated 17 October 2026 · Fact-checked

E-business is the conduct of industry, trade and commerce using computer networks; e-commerce is the narrower part that covers online dealings with buyers and sellers, so e-commerce is a subset of e-business. Its scope covers B2B (business to business), B2C (business to customer), intra-B (within the firm, also called B2E) and C2C (customer to customer).

Notice that e-commerce sits inside e-business as a subset, while Intra-B (within the firm) is e-business but not e-commerce.

Understand E-business, E-commerce and Their Scope: B2B, B2C, Intra-B and C2C (CBSE 11)

E-business. The conduct of industry, trade and commerce using computer networks (the internet, intranets and extranets). It covers all business functions: production, marketing, finance, human resources and relations with suppliers and customers.

E-commerce. The online dealings of a firm with its buyers and sellers: taking orders, buying and selling, and sending or receiving payments. Every e-commerce activity is e-business, but e-business also includes internal processes such as online inventory management, payroll and staff training. So e-commerce is a subset of e-business.

Scope of e-business.

  • B2B (business to business): both parties are businesses.
  • Procurement of inputs: ordering raw materials and components electronically; sharing production plans with suppliers so that parts arrive just in time and inventory is reduced.
  • Supply chain management: tracking orders, shipments and payments.
  • Distribution and dealer networks: dealers order and check stock online.
  • Payments: electronic fund transfer between firms.
  • Example: a car maker's system orders tyres automatically when stock falls below a set level.
  • B2C (business to customer): a business deals with consumers: online shopping, banking, ticket booking, food delivery, learning platforms. The firm can track preferences, give quick after-sales service and reach customers 24 x 7. Customer-to-business (C2B) flows such as feedback or bidding are also included.
  • Intra-B (business to employee, B2E): networks within the firm for communication among departments and employees: online attendance, leave and payroll, internal email, video meetings, e-learning, and coordination of production, sales and stores so that the firm can produce to order.
  • C2C (customer to customer): consumers deal directly with other consumers through an online platform such as an auction or classifieds site, to sell second-hand books, furniture, phones or cars. The platform provides the market space and sometimes a payment and safety mechanism.

  4. Q4 · 4 marks · Short answerHarder board level

    A shop in a market pays rent of 80,000 and staff salaries of 40,000 a month. Online, the same business would pay 25,000 for the website and 30,000 for staff. Find the yearly saving in these costs and state two other differences between a traditional business and e-business. (4 marks)

    Hint

    Subtract monthly costs first.

    Answer

    Monthly cost of the shop = 80,000 + 40,000 = 1,20,000. Online = 25,000 + 30,000 = 55,000. Monthly saving = 65,000; yearly saving = 65,000 x 12 = 7,80,000. Other differences: physical presence is required in traditional business but not in e-business; going global is easier in e-business; personal touch is higher in traditional business.
