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:

| 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 |

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