E-Commerce Basics: Definitions, Models & Evolution

What is E-Commerce?

E-commerce (electronic commerce) is the buying and selling of goods/services over the internet using digital platforms. It includes transactions between businesses (B2B), businesses and consumers (B2C), consumers and consumers (C2C), and more.

Key Definitions

• E-Commerce: Digital exchange of goods/services, payments, and data.
• E-Business: Broader than e-commerce; includes internal business processes (e.g., HR, supply chain) via digital tools.
• Digital Commerce: Synonymous with e-commerce but emphasizes mobile and social media transactions.

How E-Commerce Works

Example: When you buy a phone on Daraz, you browse (B), add to cart (C), pay via Khalti/eSewa (D), and receive the product (E).

Evolution of E-Commerce

E-commerce has evolved through four generations:

Types of E-Commerce Models

E-commerce operates through six primary models:

Example: Ncell’s digital wallet uses B2C (selling mobile recharge) and C2G (paying utility bills).

    Products/Services
    Payment Systems
    Security & Privacy
    Marketing & Promotion
    Logistics & Fulfillment

1. Products/Services

• Digital Goods: Software, e-books (e.g., Nepali e-library apps).
• Physical Goods: Electronics, groceries (e.g., Daraz, Hamrobazaar).
• Services: Travel booking (e.g., Yatra.com), freelancing (e.g., Upwork).

2. Payment Systems

• Cash on Delivery (COD): Still dominant in Nepal (~60% of e-commerce).
• Digital Wallets: Khalti, eSewa, Ncell Purse.
• Bank Transfers: IME Pay, Connect IPS.
• Credit/Debit Cards: Rare in Nepal but used in global e-commerce.

Example: Khalti uses tokenization (storing card details securely) to process payments.

Advantages & Disadvantages of E-Commerce

Nepali Case Study: Daraz struggles with last-mile delivery in remote areas but benefits from low overhead costs compared to physical stores.

In the Real World

1. eSewa (Nepal)

   • Uses C2G model for bill payments (electricity, phone).
   • Implements two-factor authentication (2FA) for security.

2. Daraz (Alibaba Group)

   • B2C platform with AI-driven recommendations (e.g., "Frequently Bought Together").
   • Logistics challenge: Partners with Nepal Post for rural deliveries.

3. Ncell Purse

   • Digital wallet enabling B2C (recharge) and C2G (tax payments).
   • Uses blockchain-like ledger for transaction transparency.

Exam Tip

• Definition: Memorize the difference between e-commerce, e-business, and digital commerce.
• Models: Know B2B vs. B2C vs. C2C with Nepali examples.
• Components: Focus on payment systems (Khalti, eSewa) and security (SSL, encryption).
• Case Study: Be ready to explain how Daraz or eSewa applies e-commerce models.
• Diagrams: Draw the e-commerce transaction flow (customer → website → payment → delivery).
