1. Understanding Electronic Commerce

Before diving into the main categories of e commerce, it’s important to define what electronic commerce actually is.

Electronic commerce (e-commerce) refers to the buying and selling of goods and services through digital platforms. These transactions occur over the internet and span various industries, customer types, and formats.

At its heart, e-commerce is simply commerce gone digital — and it’s booming. As of 2025, e-commerce sales in the U.S. alone are projected to top $1.7 trillion.


2. The Four Main Categories of Electronic Commerce

Most discussions about types of ecommerce refer to four primary categories. These are based on who is selling to whom:

Category Also Known As Who’s Involved Examples
B2C (Business to Consumer) Retail e-commerce Businesses selling to individuals Amazon, Walmart.com, Nike.com
B2B (Business to Business) Wholesale e-commerce Companies selling to other companies Alibaba, Salesforce, Grainger
C2C (Consumer to Consumer) Peer-to-peer Individuals selling to individuals eBay, Facebook Marketplace
C2B (Consumer to Business) Reverse e-commerce Consumers offering products/services to businesses Shutterstock, Upwork

Each of these kinds of e commerce operates differently and caters to specific customer journeys.


3. B2C E-Commerce: The Powerhouse of Online Retail

B2C (Business to Consumer) is what most people think of when they hear “online shopping.”

  • Examples: Amazon, BestBuy.com, Target.com
  • Product Types: Physical goods, digital downloads, services
  • Buying Cycle: Short and emotionally driven
  • Marketing Focus: Discounts, convenience, personalized ads

This is the dominant model in the U.S. and represents the fastest-growing segment among all types of ecommerce businesses.


4. B2B E-Commerce: The Digital Supply Chain

Business to Business (B2B) commerce involves transactions between businesses. Think bulk orders, inventory systems, and enterprise tools.

  • Examples: Alibaba, Grainger, Oracle
  • Product Types: Raw materials, SaaS, parts, enterprise services
  • Buying Cycle: Longer, more rational, budget-based decisions
  • Marketing Focus: Value propositions, contracts, ROI, demos

This category of electronic commerce models often flies under the radar but drives trillions in annual transactions.


5. C2C E-Commerce: From Your Garage to Someone Else’s Inbox

With the rise of platforms like eBay and Facebook Marketplace, consumer-to-consumer (C2C) ecommerce has exploded.

  • Examples: Craigslist, eBay, Poshmark
  • Product Types: Used goods, handmade crafts, collectibles
  • Buying Cycle: Fast and price-sensitive
  • Challenges: Trust, scams, returns

C2C represents one of the most community-driven ecommerce business models.


6. C2B E-Commerce: When Consumers Call the Shots

Consumer-to-business (C2B) flips the traditional script. Here, individuals sell their services or creations to companies.

  • Examples: Upwork (freelance), Shutterstock (stock images), Fiverr
  • Product Types: Skills, ideas, content
  • Growth Drivers: Gig economy, creator economy

This model empowers individuals and has gained huge momentum post-pandemic.


7. Emerging Types of Ecommerce Models

Beyond the core four, newer ecommerce business models are reshaping the digital marketplace:

  • B2B2C (Business to Business to Consumer): A business sells to another business that sells to consumers (e.g., Instacart)
  • D2C (Direct to Consumer): Brands sell directly to buyers, skipping intermediaries (e.g., Warby Parker, Glossier)
  • G2C (Government to Consumer): Digital tax filing, e-licensing

These types of ecommerce companies combine the strengths of traditional models with modern UX and automation.


8. Electronic Commerce Models by Product Type

Product Type Common E-Commerce Models Examples
Physical Goods B2C, B2B, C2C Amazon, Alibaba, eBay
Digital Products B2C, C2B, D2C Udemy, Canva, Gumroad
Services C2B, B2B, B2C Upwork, Fiverr, TaskRabbit

  • If you’re an individual creator → C2B or D2C is your sweet spot
  • If you’re selling in bulk to other companies → B2B is your model
