E-commerce: Models, Value Chains & Business Types

TAKEAWAYS:

• E-commerce is a digital marketplace enabled by the internet, transforming traditional commerce into online transactions.
• Value chains (internal processes) and value webs (external partnerships) are critical for competitive advantage in e-commerce.
• Business models like B2C (e.g., Daraz), B2B (e.g., NEPSE), and C2C (e.g., OLX) define how value is exchanged in digital ecosystems.
• Pricing models (e.g., CPC, CPM) and auction types (e.g., English, Dutch) drive revenue and customer engagement.
• Social e-commerce (e.g., Facebook Marketplace) leverages community trust and viral marketing.
• Security threats (e.g., phishing, fraud) require cryptographic tools (hash functions, encryption) to protect transactions.

Types of E-commerce

E-commerce is classified based on transaction participants:

In the real world

• eSewa (B2C): Uses digital wallets and secure payment gateways to enable instant transactions between users and businesses. Example: Paying for a Daraz order via eSewa’s encrypted server.
• NEPSE (B2B): Facilitates auction-based trading (English auction) for stocks, where buyers bid in real-time for shares.
• Pathao (B2C): Leverages geolocation and real-time booking to match riders with customers, optimizing supply chains digitally.

2. Value Chain vs. Value Web in E-commerce

Value Chain

A value chain is the internal sequence of activities a business performs to deliver a product/service to the market. It includes:

• Inbound logistics (supplier → business)
• Operations (production)
• Outbound logistics (business → customer)
• Marketing & sales
• Service

Value Web

A value web extends the value chain externally, involving partnerships, suppliers, distributors, and competitors working collaboratively. Example:

• Daraz (B2C) partners with Ncell (logistics) and eSewa (payments) to form a value web.

Comparison Table

Worked Example: Daraz’s Value Chain & Web

1. Inbound Logistics: Daraz imports goods from suppliers (value chain).
2. Operations: Warehousing and inventory management (value chain).
3. Outbound Logistics: Ncell delivers packages (value web partner).
4. Marketing: Facebook ads (value web, leveraging social media).
5. Service: Customer support via WhatsApp (value web, using a third-party platform).

3. E-commerce Business Models

Business models define how value is created, delivered, and captured in e-commerce. Key models include:

B2C (Business-to-Consumer)

• Model: Business sells directly to end-users.
• Examples: Daraz, Amazon, Flipkart.
• Revenue Streams:
  • Product sales
  • Subscription fees (e.g., Amazon Prime)
  • Advertising (e.g., sponsored products)

B2B (Business-to-Business)

• Model: Bulk transactions between businesses.
• Examples: NEPSE (stock trading), Alibaba B2B.
• Revenue Streams:
  • Commission on trades
  • Subscription-based platforms (e.g., SAP for enterprises)

C2C (Consumer-to-Consumer)

• Model: Peer-to-peer transactions.
• Examples: OLX, Facebook Marketplace.
• Revenue Streams:
  • Listing fees
  • Transaction commissions

Marketplace Model (Hybrid)

• Model: Platform connects buyers and sellers (e.g., Daraz, eBay).
• Revenue Streams:
  • Commission per sale
  • Advertising
  • Subscription for premium features

    D["Seller"] -->|"Lists Product"| B
    E["Advertiser"] -->|"Ads"| B
    B -->|"Data Analytics"| F["Personalization Engine"]

In the real world

• NEPSE (B2B): Uses an auction-based model where investors bid for stocks in real-time, similar to how Daraz handles flash sales.
• OLX (C2C): Relies on user-generated listings and community trust, reducing the need for a traditional value chain.
• Daraz (Marketplace): Combines B2C (direct sales) and C2C (seller listings) under one platform, maximizing revenue streams.

4. Pricing Models in Online Advertising

Advertisers use different pricing models to display ads on e-commerce platforms. Common models include:

Worked Example: Daraz’s Ad Pricing

• A shoe brand runs a CPC campaign on Daraz, paying ₹20 per click.
• If 500 users click the ad but only 50 convert to sales, the brand pays ₹10,000 for clicks but may generate ₹50,000 in revenue, making it cost-effective.

5. Auctioning in E-commerce

Auctions are real-time bidding mechanisms used in e-commerce for dynamic pricing. Types include:

English Auction (Ascending Bid)

• How it works: Bidders increase bids until no one else bids.
• Example: NEPSE stock trading, eBay auctions.
• Advantage: Highest bidder wins at the highest price.
• Disadvantage: Can drive prices artificially high.

Dutch Auction (Descending Bid)

• How it works: Seller starts with a high price and reduces until a buyer accepts.
• Example: IPOs (Initial Public Offerings), some cryptocurrency sales.
• Advantage: Encourages competitive bidding from below.
• Disadvantage: May undervalue items.

Reverse Auction (B2B)

• How it works: Buyers bid downwards for a product/service.
• Example: Government tenders, procurement auctions.
• Advantage: Lowest cost for buyers.
• Disadvantage: Sellers may underprice.

In the real world

• NEPSE (English Auction): Investors bid upwards for stocks, similar to how Daraz handles flash sales where prices rise with demand.
• Cryptocurrency Sales (Dutch Auction): Projects like Bitcoin used Dutch auctions to set initial prices, ensuring fair distribution.
• Government Tenders (Reverse Auction): Nepal’s public procurement uses reverse auctions to get the best deals for infrastructure projects.

6. Social E-commerce and Marketing Strategies

Social e-commerce integrates social media platforms into the buying process, leveraging community trust and viral marketing.

Key Strategies

1. Social Proof: Reviews, ratings, and user-generated content (e.g., Instagram posts for Daraz products).
2. Influencer Marketing: Partnering with influencers to promote products (e.g., Pathao’s ride-sharing ads on YouTube).
3. Community Engagement: Facebook Groups, WhatsApp Business for customer support.
4. User-Generated Content: Customers post unboxing videos (e.g., TikTok for Daraz).

Drivers of Social E-commerce Growth

Worked Example: Daraz’s Social E-commerce

• Strategy: Runs Facebook Shop and Instagram ads targeting Nepali youth.
• Result: 40% of Daraz’s sales come from social media referrals.
• Tactic: Influencers like @nepalfoodie promote Daraz’s kitchenware, driving 10,000+ clicks per post.

7. Security Threats and Protections in E-commerce

E-commerce faces cybersecurity threats that can compromise transactions. Key threats and solutions:

Security Threats

Security Measures

    C -->|"Hashing"| D["Database (Server-Side)"]
    D -->|"Firewall"| E["Secure Server"]
    F["Hacker"] -->|"Blocked"| G["Firewall"]

In the real world

• eSewa (Hash Functions): Uses SHA-256 to store passwords securely, preventing hackers from accessing plaintext data.
• Daraz (SSL/TLS): Encrypts all transactions to prevent man-in-the-middle attacks during checkout.
• Ncell (2FA): Requires SMS OTP for mobile banking, adding an extra layer of security.

8. Developing an E-commerce Website

Key elements to consider when building an e-commerce platform:

Essential Components

1. User Interface (UI): Must be mobile-friendly (90% of Nepali users browse via mobile).
2. Payment Gateway: Integrate eSewa, Khalti, or credit cards for secure transactions.
3. Inventory Management: Real-time stock tracking (e.g., Daraz’s warehouse system).
4. Search & Filtering: AI-driven product recommendations (e.g., "Customers also bought...").
5. Customer Support: Live chat, WhatsApp Business, and FAQs.
6. SEO Optimization: Ensure visibility on Google (e.g., Daraz ranks #1 for "buy online Nepal").

Worked Example: Pathao’s Website

• UI: Simple, one-tap booking interface.
• Payment: Supports eSewa, Khalti, and cash on delivery.
• Inventory: Real-time driver availability via GPS.
• Support: 24/7 WhatsApp chat for ride queries.

Exam Tip

This unit is highly conceptual but requires real-world examples to score full marks. Focus on:

1. Definitions: Clearly explain value chain vs. value web, B2C vs. B2B, and auction types.
2. Examples: Always tie theory to Nepali companies (eSewa, Daraz, NEPSE) or global platforms (Amazon, Alibaba).
3. Comparisons: Use tables for pricing models, auction types, and security threats.
4. Process Flow: Draw Mermaid diagrams for value chains, payment flows, and security layers.
5. Current Trends: Mention social e-commerce (Facebook Shop) and mobile-first design (Pathao).

Common Pitfalls to Avoid:

• Overgeneralizing: Don’t say "e-commerce is just online shopping"—explain business models.
• Ignoring security: Always link hash functions, SSL, and 2FA to real examples.
• Missing Nepal-specific cases: Use eSewa, Daraz, NEPSE where possible.

Final Checklist for Full Marks ✅ Define key terms (e-commerce, value chain, B2C/B2B). ✅ Compare value chain vs. web, auction types, pricing models. ✅ Example every concept with Nepali or global platforms. ✅ Visualize processes with Mermaid diagrams or real images. ✅ Discuss security threats and solutions with real-world cases.
