Definition
The checkout process is the final series of steps a customer performs to complete a purchase on an e-commerce website. It includes reviewing the cart, entering shipping and billing information, choosing a payment method, and confirming the order. A smooth, secure, and user-friendly checkout process is critical to converting visitors into paying customers.

Why It Matters
A well-designed checkout process reduces cart abandonment and increases sales. If the process is confusing, slow, or requires too much effort, customers may leave before completing their purchase. A good checkout experience builds trust, improves customer satisfaction, and encourages repeat business. It also helps ensure that orders are processed accurately and efficiently.

How It’s Used
On a website, the checkout process usually starts when a user clicks “Checkout” from their cart. They are taken through one or more pages (or a single page) where they:
- Review their order
- Enter shipping address
- Choose delivery options
- Provide payment details
- Review and confirm their order
- E-commerce platforms like Shopify, WooCommerce, and BigCommerce offer customizable checkout flows to optimize this experience.
Example in Action
An online bookstore has a simple, one-page checkout process. After selecting a few books, the customer clicks “Checkout,” enters their shipping info, selects a payment method, and confirms the purchase—all on the same page. They receive an instant confirmation and email receipt. The process is fast, secure, and mobile-friendly, leading to higher conversions.
