What is one-click checkout?

One-click checkout is a checkout approach that allows customers to complete a purchase with very few steps, often using previously saved payment, shipping, and customer information. Instead of manually entering the same details through a multi-step checkout, returning customers can confirm their purchase quickly.

Key features can include:

• Saved customer information: Shipping and contact details can be reused.
• Saved payment methods: Customers can use an eligible stored payment method.
• Minimal steps: Reduces unnecessary navigation and data entry.
• Mobile-friendly purchasing: Makes checkout faster on smaller screens.
• Express payment options: Services such as Shop Pay, Apple Pay, or Google Pay can provide accelerated checkout experiences where supported.

For example, a returning customer who has previously saved their details may be able to select an express checkout option and confirm an order without manually entering their address and payment information again.

In CRO, one-click or accelerated checkout can reduce checkout friction and abandonment, particularly for repeat customers and mobile shoppers. However, businesses should still provide clear order details, pricing, shipping information, and security indicators so customers can review their purchase before completing it.
