How do I customize checkout on Shopify Plus beyond standard options?

On Shopify Plus, you can customize checkout beyond standard options using Checkout Blocks, the Checkout Branding API, Shopify Extensions, and Shopify Functions. These tools allow advanced visual styling, custom fields, dynamic shipping and payment rules, and separate B2B and D2C checkout flows.

Ways to Customize Checkout on Shopify Plus

Shopify Plus provides enterprise-level checkout customization that goes far beyond basic branding settings available on standard plans.

1. Checkout Blocks (No-Code Customization)

Checkout Blocks is the primary no-code tool for modifying checkout behavior and content.

• Add custom input fields (gift messages, delivery notes, tax IDs)
• Insert dynamic content blocks
• Hide, rename, or reorder payment and shipping methods
• Set minimum or maximum order values
• Create advanced discount logic
• Show or hide blocks based on cart value, customer tags, or B2B status

Plus merchants can customize the information, shipping, and payment steps directly in the checkout editor.

2. Checkout Branding API (Advanced Visual Control)

The Checkout Branding API allows deep visual customization of checkout.

• Custom color schemes and button styles
• Typography control (fonts, weights, letter spacing)
• Layout adjustments (header, footer, one-page or multi-step)
• Custom logos and background images
• Border styles, spacing, and element radius

This ensures checkout fully matches your brand identity.

3. Shopify Extensions (Custom Functionality)

Shopify Extensions allow developers to add advanced interactive features inside checkout.

• Custom UI elements
• Post-purchase upsells
• Field validation logic
• ERP or CRM integrations
• Custom tracking pixels

This replaces the older checkout.liquid customization method, which is now deprecated.

4. Shopify Functions (Dynamic Business Rules)

Shopify Functions allow you to create custom logic that runs directly inside checkout.

You can:

• Hide or reorder payment methods conditionally
• Control shipping options based on cart value or location
• Create complex discount structures
• Set dynamic B2B payment terms
• Flag high-risk orders for review

This is especially useful for blended B2B and D2C stores.

5. Market-Specific Checkout Customization

Shopify Plus allows checkout customization by market. You can:

• Change branding per country
• Offer market-specific payment methods
• Localize messaging and content
• Create separate B2B and D2C checkout experiences

Important Limitations

• checkout.liquid is deprecated
• Additional Scripts are no longer supported
• Customizations must be built using Checkout Extensions, Functions, or apps

Best Practices for Checkout Customization

• Test changes with both B2B and D2C accounts
• Keep checkout fast and lightweight
• Design mobile-first
• A/B test major changes
• Ensure accessibility compliance

Final Takeaway

Shopify Plus gives merchants full control over checkout through Checkout Blocks, Branding APIs, Extensions, and Shopify Functions. These tools allow you to create branded, personalized, and conversion-optimized checkout flows that support complex business logic and multiple customer types.
