What Is E-commerce?

E-commerce refers to buying and selling goods or services online. Unlike traditional brick-and-mortar retail, which depends on in-person rates through digital platforms that enable transactions anytime and from anywhere. Online storefronts offer key advantages, including 24/7 availability and access to a global customer base. Driven by  rapid digitalization, e-commerce has become an integral part of everyday life for consumers worldwide. In fact, an estimated 2.14 billion people made online purchases in 2021¹—accounting for roughly 27% of the global population!

There are several e-commerce models:

B2C – Business-to-Consumer: This is the most widely recognized model. It involves businesses —typically retailers —selling products or services directly to end customers through online channels. Examples include supermarket, fashion brands, boutique retailers with their own websites, and subscription- based platforms.

B2B – Business-to-Business: This model focuses on transactions between businesses. It commonly includes wholesale trade, where companies purchase goods in bulk to resell to other businesses or final consumers. While traditionally reliant on in-person negotiations, digital transformation has shifted much of this activity online, making it one the fastest-growing segments in e-commerce.

C2C – Consumer-to-Consumer: This model refers to transactions between private individuals who buy and sell goods or services online. These exchanges are typically facilitated by third-party platforms or marketplaces, such as Facebook Marketplace or similar services.

C2B – Consumer-to-Business: In this setup, individuals offer products or services to businesses. Examples include content creators selling advertising space, freelancers providing services, or photographers licensing their work through digital platforms.
