Checkout

What is Checkout?

Checkout is the final stage of the purchase flow, where a customer moves from the shopping cart to a completed order. This is where they enter contact, shipping, and payment details, choose a delivery method, and authorize the payment. In Shopify, checkout is served by Shopify’s own secure infrastructure on your store’s own domain and, unlike product and collection pages, cannot be freely edited with ordinary Liquid theme templates.

Why does Checkout matter?

Checkout is where traffic turns into revenue, so even small points of friction cost sales directly. The average cart abandonment rate sits around 70%, and long forms, unclear shipping costs, or forced account creation are among the most common causes. A fast, clear checkout with few fields and recognizable payment methods raises conversion and reduces support requests.

Common use cases

• Reduce friction. Offer guest checkout and remove unnecessary fields so customers can finish quickly.
• Accelerated payment. Enable Shop Pay and wallets (Apple Pay, Google Pay) that pre-fill saved details in one tap.
• Transparent costs. Show shipping, fees, and delivery time before the payment step to avoid surprises.
• Payment setup. Choose the right methods through your payment gateway and test with realistic orders.

Shopify perspective

Standard-plan stores use Shopify’s optimized one-page checkout, controlled through settings and the branding editor rather than theme code. Deep customization — extra fields, logic, or steps — requires Shopify Plus and Checkout Extensibility (checkout UI extensions and the Branding API), which replaced the deprecated checkout.liquid. Avoid apps that still assume checkout.liquid, and test the full flow with a real test order.
