What Is an E-commerce Business (and an E-commerce Website)? Types, Examples, How It Works and How to Start
What an ecommerce business is and what an ecommerce website is
In this article
An e-commerce business sells products or services online, taking orders and payments over the internet through a website, app, marketplace or social platform. An e-commerce website is the online store itself: product pages, a shopping cart, checkout and payment processing, connected to inventory, shipping and customer accounts.
How an e-commerce website works
- Customer browses products and categories
- Adds items to a cart
- Completes checkout (address, shipping, payment)
- Payment gateway processes the transaction
- Order goes to fulfilment (warehouse, 3PL, supplier or digital delivery)
- Customer receives confirmation and tracking
- Post-purchase: support, returns, reviews, marketing
