1. UNDERSTANDING E-COMMERCE BUSINESS MODELS
An e-commerce business model explains how an organization creates, delivers and captures value through digitally enabled commercial activities.
It answers several fundamental questions:
- Who are the customers?
- What value is being offered?
- How are customers reached?
- How are transactions facilitated?
- How does the organization generate revenue?
- What resources and partners are required?
- How does the organization sustain competitive advantage?
Technology is therefore only one component of an e-commerce business model.
Two organizations can use similar technologies while operating fundamentally different models.
For example, one organization may own inventory and sell directly to customers, while another may simply connect independent buyers and sellers and earn a commission.
2. MAJOR E-COMMERCE TRANSACTION MODELS
2.1 Business-to-Consumer (B2C)
B2C occurs when a business sells directly to individual consumers through digital channels.
Typical characteristics include:
- High customer volumes.
- Digital product discovery.
- Online ordering.
- Digital marketing.
- Customer reviews.
- Digital payments.
- Delivery and returns.
2.2 Business-to-Business (B2B)
B2B involves transactions between organizations.
Examples include:
- Digital procurement.
- Wholesale ordering.
- Enterprise software.
- Industrial supplies.
- Supplier platforms.
B2B transactions may involve longer purchasing cycles, negotiated contracts and integration with enterprise systems.
2.3 Consumer-to-Consumer (C2C)
C2C involves transactions between individuals, often facilitated by a digital marketplace.
The platform may provide:
- Listings.
- Search.
- Communication.
- Reviews.
- Payments.
- Dispute resolution.
2.4 Consumer-to-Business (C2B)
C2B occurs when individuals provide products, services, information or other forms of value to businesses.
Digital platforms have made this model increasingly feasible by connecting individual providers with organizations.
2.5 Business-to-Government (B2G)
B2G involves businesses providing products or services to public institutions through digital procurement and related systems.
3. DIGITAL PLATFORMS
A digital platform is a technology-enabled environment that facilitates interactions between two or more participant groups.
These may include:
- Buyers.
- Sellers.
- Service providers.
- Advertisers.
- Developers.
- Consumers.
The platform creates infrastructure through which participants can discover, communicate, transact and exchange value.
The OECD’s 2025 e-commerce framework specifically strengthens guidance concerning digital intermediation platforms, reflecting their increasing importance in modern commerce.
4. ONLINE RETAILERS VERSUS DIGITAL INTERMEDIARIES
An online retailer generally:
- Purchases or controls inventory.
- Determines product offerings.
- Sells directly to customers.
- Manages or coordinates fulfilment.
- Earns revenue from sales.
A digital intermediary platform may instead:
- Connect independent sellers and buyers.
- Facilitate transactions.
- Provide payment infrastructure.
- Operate reputation systems.
- Establish participation rules.
- Earn commissions or transaction fees.
The distinction is strategically important because ownership, costs, risks and governance responsibilities differ substantially.
5. MULTI-SIDED PLATFORM MODELS
A multi-sided platform serves multiple participant groups whose interactions create value.
A simplified structure is:
Sellers ↔ Digital Platform ↔ Buyers
The platform must provide sufficient value to each side.
For example:
- More sellers can increase product variety.
- Greater variety can attract more buyers.
- More buyers can increase the attractiveness of the platform to sellers.
This creates the foundation for network effects.
6. NETWORK EFFECTS
A network effect occurs when the value of a platform changes as the number or quality of participants changes.
Direct Network Effects
The value increases directly as more users participate.
Indirect Network Effects
Growth on one side increases value for another side.
For example:
More sellers → Greater choice → More buyers → Greater seller interest
Network effects can accelerate growth but can also create challenges involving:
- Market concentration.
- Fraud.
- Quality control.
- Competition.
- Platform governance.
7. E-COMMERCE REVENUE MODELS
Common revenue approaches include:
- Direct sales.
- Subscriptions.
- Commissions.
- Transaction fees.
- Advertising.
- Freemium services.
- Affiliate revenue.
- Licensing.
A platform can combine several models.
For example, it may generate revenue through transaction commissions while also selling advertising and premium services.
8. SUBSCRIPTION MODELS
A subscription model generates recurring revenue by charging customers periodically for continued access.
Advantages include:
- Predictable recurring revenue.
- Long-term customer relationships.
- Greater revenue visibility.
Challenges include:
- Customer churn.
- Retention costs.
- Continuous service expectations.
- Pressure to demonstrate ongoing value.
9. PLATFORM GOVERNANCE
As platforms grow, governance becomes increasingly important.
Platform governance determines:
- Who can participate.
- What may be sold.
- How transactions are conducted.
- How disputes are handled.
- How reviews are managed.
- How fraud is addressed.
- How data is governed.
Poor governance can undermine trust and damage the entire platform ecosystem.
10. PLATFORM ECOSYSTEMS
An e-commerce platform may depend on an ecosystem involving:
- Sellers.
- Customers.
- Payment providers.
- Logistics companies.
- Technology providers.
- Advertisers.
- Developers.
- Regulators.
The platform manager must therefore consider the health of the entire ecosystem rather than focusing only on individual transactions.
11. INTERNATIONAL PERSPECTIVE
E-commerce business models increasingly operate across borders.
The WTO recognizes that digital technologies are transforming how goods, services and intellectual property are produced and distributed internationally. Its work on electronic commerce addresses trade-related issues arising from these developments.
UNCTAD similarly emphasizes the importance of digital platforms, infrastructure, skills, investment and enabling policy environments in determining how economies participate in the digital economy.
This means e-commerce managers must consider both commercial strategy and the wider international digital environment.
12. SELECTING AN E-COMMERCE BUSINESS MODEL
Managers should evaluate:
Customer Segment
Who is being served?
Value Proposition
What problem is being solved?
Transaction Structure
Who buys from whom?
Technology
What digital infrastructure is required?
Revenue
How will the organization earn money?
Operations
How will products or services be delivered?
Competitive Environment
What alternatives are available?
Governance
What rules and controls are necessary?
13. STRATEGIC RISKS
Different models create different risks.
A direct retailer may face:
- Inventory risk.
- Fulfilment costs.
- Customer acquisition costs.
A platform may face:
- Participant trust problems.
- Fraud.
- Regulatory scrutiny.
- Network dependence.
- Content or product quality problems.
A subscription business may face:
- High churn.
- Customer fatigue.
- Increasing service expectations.
Managers must therefore assess business models according to their entire economic and operational structure.
14. INTERNATIONAL MEASUREMENT AND STANDARDS
The measurement of e-commerce requires consistent definitions.
The OECD’s 2025 definition maintains a focus on electronic ordering while providing updated guidance for developments such as digital intermediaries, subscriptions and AI-assisted transactions.
UNCTAD works with international organizations to improve the availability and comparability of e-commerce and digital economy statistics.
These frameworks help governments, researchers and businesses better understand the scale and characteristics of digital commerce.
Lesson Summary
E-commerce business models determine how digital organizations create, deliver and capture value.
The major transaction models include:
- B2C.
- B2B.
- C2C.
- C2B.
- B2G.
Digital platforms have introduced new forms of value creation based on:
- Intermediation.
- Multi-sided markets.
- Network effects.
- Ecosystems.
- Data.
- Platform governance.
The key principle is:
Successful e-commerce requires alignment between the customer, value proposition, technology, operating model, revenue model and governance structure.
