Shopify Checkout is one of the most effective checkout solutions on the market. It is lightning-fast, secure, and optimized for conversion – and with the latest features in Shopify Plus and Shopify Functions, you now have more flexibility than ever.
In this guide, we will go through how Shopify Checkout works, what you can customize, and how to get the most out of it.
What is Shopify Checkout?
Shopify Checkout is the flow your customers go through to pay on your webshop. It is a hosted solution that Shopify manages centrally – and that all Shopify webshops use.
The checkout flow typically consists of:
- Entering email or phone number
- Delivery address and method
- Payment method and confirmation
The checkout is mobile-optimized, fast, and designed to ensure the highest possible conversion.
Advantages of Shopify Checkout
- Stability and performance:Shopify Checkout has extremely high uptime and low latency.
- Safety:PCI-compliant and automatically updated
- Conversion optimized:Designed to reduce friction and get as many people as possible to complete it.
- Compatibility:Supports all major payment solutions, including MobilePay, Klarna, and Apple Pay.
What can you customize in Shopify Checkout?
The options depend on your Shopify plan, but generally, you can:
- Adjust the design:Logo, colors, fonts, button texts
- Add fields:For example, "where did you hear about us" or a checkbox for the newsletter (requires app or Plus).
- Automate discount codes and campaigns
- Manage delivery options and conditions
