What Does Single Click Checkout Mean on Shopify?

On Shopify, single click checkout usually means the accelerated checkout feature. These feature options save the buyer’s details so returning shoppers can complete checkout in just a tap or two. 

For a new store, this is the simplest way to reduce checkout friction for returning customers.

For Shopify merchants, single click checkout also means a post-purchase one-click offer. 

This means the customer completes the checkout, sees an offer in the thank-you page, and buys it without re-entering payment details. 

That’s why many single click checkout apps focus on post-purchase and thank-you page upsells. It keeps checkout upsells simple, feels low effort for the buyer, and helps you lift AOV without risking more drop-offs before payment.
