E-Commerce Models: Types, Workflows & Real-World Cases

1. What is an E-Commerce Business Model?

An e-commerce business model defines how a company creates, delivers, and captures value online. It answers:

• Who are the customers (B2B, B2C, C2C)?
• What products/services are sold?
• How is revenue generated (subscriptions, ads, commissions)?
• What technology/infrastructure supports it?

Why it matters: Models determine profitability, scalability, and competitive advantage. For example, Daraz (Nepal) uses a B2C + marketplace model, while Khalti operates as a C2B (consumer-to-business) payment gateway.

2. Core E-Commerce Business Models

E-commerce models are classified based on participants (who buys/sells) and revenue mechanisms. Below is a decision tree to identify the right model for your business:

graph TD
    A["E-Commerce Model"] --> B["By Participants"]
    B --> C["B2B: Business-to-Business"]
    B --> D["B2C: Business-to-Consumer"]
    B --> E["C2C: Consumer-to-Consumer"]
    B --> F["C2B: Consumer-to-Business"]
    B --> G["B2G: Business-to-Government"]
    B --> H["C2G: Consumer-to-Government"]
    A --> I["By Revenue Model"]
    I --> J["Transaction Fee: % of sale (e.g., Daraz)"]
    I --> K["Subscription: Recurring payment (e.g., Netflix)"]
    I --> L["Advertising: Free service + ads (e.g., YouTube)"]
    I --> M["Affiliate Marketing: Commissions (e.g., Amazon Associates)"]
    I --> N["Dropshipping: No inventory (e.g., Shopify stores)"]

A. B2B (Business-to-Business)

Definition: Businesses sell to other businesses (e.g., wholesalers, manufacturers). Examples:

• Alibaba (global B2B marketplace for bulk orders).
• Nepal’s TradeEye (connects exporters to importers).
• NTC’s e-procurement portal (government agencies buy telecom equipment online).

How it works:

1. Supplier (e.g., a factory) lists products (e.g., textiles, electronics).
2. Buyer (e.g., a retail chain like Big Mart) places bulk orders.
3. Payment via e-invoicing or bank transfers.
4. Logistics handled by third-party providers (e.g., DHL, Gati).

Worked Example: Nabil Bank’s Digital Loans for SMEs

• Model: B2B (bank → small businesses).
• Workflow:
  1. SMEs apply online via Nabil’s e-banking portal.
  2. Bank verifies credit score (via CRISIL or TransUnion CIBIL).
  3. Loan disbursed digitally (no paperwork).
  4. Repayment via auto-debit or Khalti/Esewa.
• Revenue: Interest + processing fees (~12–18% p.a.).

Pros/Cons:

B. B2C (Business-to-Consumer)

Definition: Businesses sell directly to end consumers (most common model). Examples:

• Daraz (Nepal’s Amazon-like marketplace).
• Amazon (global B2C giant).
• Himalayan Java (online coffee sales).

How it works:

1. Product listing (with images, descriptions, prices).
2. Customer browses (via website/app).
3. Checkout (payment via Khalti, Esewa, credit card).
4. Fulfillment (inventory → shipping → delivery).

Worked Example: Daraz’s "Lightning Deals"

• Model: B2C + flash sales (limited-time discounts).
• Workflow:
  1. Daraz partners with brands (e.g., Pashmin, Himalayan Java).
  2. Runs countdown promotions (e.g., "50% off in 2 hours!").
  3. Customers rush to buy via Daraz app.
  4. Revenue split: Daraz takes 10–15% commission; seller gets the rest.
• Tech used: AI-driven demand forecasting, real-time inventory tracking.

Pros/Cons:

C. C2C (Consumer-to-Consumer)

Definition: Consumers sell to other consumers (peer-to-peer). Examples:

• OLX Nepal (classifieds for used goods).
• Facebook Marketplace (local sales).
• eBay (global C2C giant).

How it works:

1. Seller posts (e.g., "Used iPhone 11, Rs. 25,000").
2. Buyer negotiates (via chat or calls).
3. Payment via bank transfer, Khalti, or cash on delivery.
4. Delivery (often via Pathao’s "Pathao Delivery").

Worked Example: OLX Nepal’s "Cash on Delivery" Model

• Model: C2C + trust-building features.
• Workflow:
  1. Seller lists an item (e.g., second-hand laptop).
  2. Buyer requests COD (no upfront payment).
  3. OLX verifies the seller’s rating (to reduce fraud).
  4. Delivery via local courier (e.g., Gati).
• Revenue: Rs. 100–500 per transaction (listing fees).

Pros/Cons:

D. C2B (Consumer-to-Business)

Definition: Consumers sell products/services to businesses. Examples:

• Fiverr/Upwork (freelancers sell skills to companies).
• Khalti’s "Pay for Services" (e.g., electricians, tutors).
• Nepal’s "Rent a Driver" apps (e.g., Karma Auto).

How it works:

1. Freelancer/Service Provider creates a profile (e.g., "Graphic Designer").
2. Business (e.g., Daraz, a startup) posts a job.
3. Matching via AI algorithms (e.g., Fiverr’s search).
4. Payment via escrow (money held until work is done).

Worked Example: Khalti’s "Service Marketplace"

• Model: C2B (consumers offer services to businesses).
• Workflow:
  1. A plumber registers on Khalti’s platform.
  2. A hotel in Kathmandu posts a job: "Fix leaky pipe, Rs. 2,000".
  3. Plumber applies; Khalti verifies ID.
  4. Hotel pays Rs. 2,000 + 5% fee to Khalti.
• Revenue: 3–10% commission per booking.

Pros/Cons:

E. Other Models

3. Hybrid Models: Combining Strategies

Many successful e-commerce businesses combine models to maximize revenue. Examples:

A. Marketplace + Subscription (Daraz Prime)

• Daraz offers:
  • Marketplace (B2C/C2C): Sellers list products.
  • Subscription (B2C): Daraz Prime (Rs. 999/year) for free shipping, early access to deals.
• Revenue streams:
  • Commission (10–15% per sale).
  • Subscription fees (Prime members).
  • Advertising (brands pay for sponsored listings).

B. B2B + B2C (Alibaba)

• Alibaba serves:
  • B2B: Wholesale buyers (e.g., Big Mart).
  • B2C: Consumers via Taobao (China’s Amazon).
• Revenue:
  • Transaction fees (B2B).
  • Ad revenue (Taobao’s search ads).

C. C2C + C2B (OLX Nepal)

• OLX allows:
  • C2C: Selling used goods.
  • C2B: Freelancers (e.g., home repair services).
• Revenue:
  • Listing fees (Rs. 100–500).
  • Service booking commissions (10%).

4. Choosing the Right Model for Your Business

Use this decision flowchart to pick a model based on your goals, resources, and target audience:

flowchart TD
    A["Start"] --> B{"Do you have a physical product?"}
    B -->|"Yes"| C{"Will you sell in bulk?"}
    C -->|"Yes"| D["B2B Model<br/>(e.g., Alibaba, TradeEye)"]
    C -->|"No"| E["B2C Model<br/>(e.g., Daraz, Himalayan Java)"]
    B -->|"No"| F{"Is it a service?"}
    F -->|"Yes"| G{"Will customers pay you?"}
    G -->|"Yes"| H["C2B Model<br/>(e.g., Fiverr, Khalti Services)"]
    G -->|"No"| I["B2C Subscription<br/>(e.g., Netflix, Coffee Clubs)"]
    F -->|"No"| J["C2C Model<br/>(e.g., OLX, Facebook Marketplace)"]

Key Questions to Ask:

1. Who is my customer? (Businesses or individuals?)
2. What’s my budget? (B2B needs more sales effort; C2C is low-cost.)
3. Do I need inventory? (Dropshipping vs. stocking goods.)
4. What’s my revenue goal? (One-time sales vs. subscriptions.)

5. Case Study: Pathao’s Ride-Hailing Model

Business Model: C2B + B2C Hybrid

• C2B: Drivers (consumers) provide rides to businesses (e.g., hotels, offices).
• B2C: Pathao connects riders (consumers) to drivers.

Workflow:

1. Driver signs up (via Khalti/Esewa verification).
2. Rider requests a ride (via app).
3. Pathao matches driver → rider (via AI routing).
4. Payment: Rider pays via Khalti/credit card; Pathao takes 20% commission.
5. Driver earns the remaining 80%.

Tech Used:

• GPS tracking (real-time location).
• Dynamic pricing (surge pricing during traffic).
• Driver ratings (to ensure quality).

Revenue Streams:

Challenges:

• Driver retention (high competition from Karma Auto).
• Regulatory hurdles (Nepal’s traffic laws).
• Fraud prevention (fake accounts, payment disputes).

6. Legal and Ethical Considerations

E-commerce models must comply with Nepal’s laws and global regulations:

Example: Daraz’s compliance in Nepal

• Tax: Collects VAT on all sales.
• Refunds: Follows 14-day return policy (as per Consumer Protection Act).
• Data: Stores customer data on AWS servers (Singapore), complying with Nepal’s IT Act.

## In the real world

1. Daraz (Nepal) – B2C + Marketplace Model

   • How it uses the idea: Combines B2C retail (selling its own brands like Daraz Fashion) with a C2C marketplace (third-party sellers).
   • Real-world impact: 70% of Nepali online shoppers use Daraz, driving Rs. 50+ billion in GMV (2023).
   • Key tech: AI-driven recommendations (e.g., "Customers who bought X also bought Y").

2. Khalti – C2B + Payment Gateway

   • How it uses the idea: Acts as a C2B platform (freelancers, service providers sell to businesses) and a B2C payment processor (e.g., eSewa traffic fines).
   • Real-world impact: 90% of Nepal’s digital payments go through Khalti/Esewa.
   • Worked example: A Kathmandu hotel uses Khalti to hire plumbers, cleaners, and event managers without upfront costs.

3. Nabil Bank’s Digital Loans – B2B + FinTech

   • How it uses the idea: B2B lending (bank → SMEs) with e-commerce integration (loans for Daraz sellers, Pathao drivers).
   • Real-world impact: 50% of Nabil’s SME loans are now digital (up from 10% in 2020).
   • Key feature: Auto-loan approval using AI + CRISIL scores.

## Exam Tip

How this unit is tested in TU/PU exams:

1. Model Identification (3–5 marks)

   • Question: "Classify the following businesses: OLX, Daraz, Alibaba, Khalti."
   • Answer Strategy:
     • OLX → C2C
     • Daraz → B2C + Marketplace
     • Alibaba → B2B
     • Khalti → C2B + Payment Gateway
   • Visual Aid: Draw a table like the one above in the exam.

2. Workflow Diagrams (5–7 marks)

   • Question: "Explain how Pathao’s ride-hailing model works with a flowchart."
   • Answer Strategy:
     • Use a Mermaid flowchart (as shown earlier).
     • Highlight key steps: Driver sign-up → Rider request → Matching → Payment split.

3. Pros/Cons Analysis (4–6 marks)

   • Question: "Discuss the advantages and disadvantages of a C2C model like OLX."
   • Answer Strategy:
     • List 3 pros (low cost, community trust, flexible).
     • List 3 cons (fraud risk, no brand control, payment issues).
     • Add a real example: "OLX Nepal faces scams where sellers don’t deliver, but its ‘verified seller’ badge helps."

4. Case Study Application (6–8 marks)

   • Question: "How could Nabil Bank use a B2B e-commerce model to improve SME lending?"
   • Answer Strategy:
     1. Identify model: B2B (Bank → SMEs).
     2. Workflow:
        • SMEs apply online (via Nabil’s app).
        • Bank uses AI to assess creditworthiness (no collateral needed).
        • Loan disbursed via Khalti/Esewa.
     3. Tech needed: Blockchain for secure transactions, chatbots for 24/7 support.
     4. Revenue: Lower default rates → higher profit margins.

5. Hybrid Model Questions (5 marks)

   • Question: "Explain how Daraz combines B2C and C2C models."
   • Answer Strategy:
     • B2C: Daraz sells its own products (e.g., Daraz Fashion).
     • C2C: Third-party sellers (e.g., local tailors) list items.
     • Revenue: Commission on C2C sales + profit from B2C products.

Common Mistakes to Avoid:

• Mixing up B2B/B2C: Remember B2B = business-to-business, B2C = business-to-consumer.
• Ignoring revenue models: Always mention how the business makes money (e.g., commissions, subscriptions).
• Overcomplicating workflows: Stick to 3–4 key steps in diagrams.
• Not using Nepali examples: Exams love Daraz, Khalti, Nabil Bank—use them!
