What is E Commerce?

E Commerce, short for electronic commerce, refers to the buying and selling of goods and services over the internet using digital platforms. It uses websites, apps and marketplaces to buy and sell goods. E commerce offers individuals a virtual shop for browsing goods and services online conveniently from their homes. Most popular online marketplaces include Amazon, Etsy, Alibaba, Shopify and WooCommerce.

Origin of E Commerce

The origin of E Commerce trace back to the 1960s with the development of Electronic Data Interchange (EDI). It enabled businesses to exchange documents electronically. The first electronic shopping, however, began in 1979 with Michael Aldrich. The invention connected TVs to transaction computers via phone lines, marking the beginning of e commerce. In the 1990s, the birth of the web and online retail strengthened today's modern e commerce. Online marketplaces like Amazon and eBay were founded in the 1990s, becoming cornerstones of the industry.

Role of E Commerce in the Marketplace

E Commerce plays a crucial role in market reach and expansion. E Commerce platforms such as Amazon, Flipkart, and Alibaba facilitate multi-vendor platforms. This helps third-party sellers list their products alongside other branded inventory. The model reduces the entry barriers for small businesses, enabling them to reach vast audiences.

Types of E Commerce Models

3. Consumer-to-Consumer (C2C): The C2C model involves individuals selling to other individuals on third-party platforms. This peer-to-peer sale model connects buyers and sellers directly. Examples include auctions, used items or handmade crafts.
4. Consumer-to-Business (C2B): Consumers offer products or services to businesses in this model. C2B finds its applications in creator economies, where freelancers or gigs pitch to be hired for tasks.
5. Business-to-Administration (B2A) and Consumer-to-Administration (C2A): These e commerce models involve government interactions for online tax payments or procurement portals.

Emerging Types of E Commerce

These types of E Commerce models allow flexibility, with many businesses blending them for a unique purpose.
