Overview

Flex merchants often see higher adoption and usage when Flex is surfaced more prominently during checkout. Shopify provides native payment customization tools that allow merchants to reorder payment methods — making it possible to highlight Flex without changing pricing, UX, or checkout flow.
Checkout customization is fully managed in Shopify and does not require any changes from Flex.

​
Why checkout placement matters

Most customers choose from the first few payment options they see at checkout. Payment order subtly communicates what’s:
  • Recommended
  • Most commonly used
  • Easiest to complete
Placing Flex higher in the list can:
  • 👀 Increase visibility
  • ⭐ Make Flex feel like a default or preferred option
  • 📈 Improve usage without additional marketing spend

​
What Shopify supports

Shopify’s native checkout payment customization allows merchants to:

Reorder payment methods

Control the order in which payment options appear during checkout.

Rename payment methods

Adjust display names to better reflect how customers should use them.

Customize presentation

Influence how payment options are surfaced to buyers.
These changes are handled entirely within Shopify and apply to supported payment methods, including Flex.

​
Flex best-practice recommendation

​
⭐ Recommended placement

We recommend placing Flex in the top 2–3 payment options at checkout. This placement is especially effective for:
  • Higher-AOV purchases
  • First-time customers
  • Moments where payment flexibility is a key value proposition
Merchants often test Flex placement during promotional periods to quickly measure impact.

​
How to reorder payment methods in Shopify

​
Option 1 (recommended): Work with a Shopify developer or partner

If you work with a Shopify developer, agency, or internal engineering team:
  1. Ask them to reorder payment methods at checkout
  2. Share Shopify’s official payment customization documentation
  3. Note that this is typically a lightweight change for teams already using Shopify Functions
For most Shopify Plus merchants, this is a straightforward configuration using existing tooling.

​
Option 2: Implement directly using Shopify documentation

For technical teams implementing this directly, Shopify documents payment method customization here: 🔗 Payment Customization Function API
https://shopify.dev/docs/api/functions/latest/payment-customization This is a Shopify-native capability and does not require Flex-specific integration work.

​
Example outcome (generalized)

A Flex merchant recently used Shopify’s payment customization tools to move Flex higher in their checkout payment list. After reordering payment methods:
  • Flex became more visible during checkout
  • Early results showed increased awareness and usage
  • The merchant expanded Flex visibility into additional marketing channels
Checkout placement can act as a force multiplier for Flex adoption with minimal implementation effort.

​
Important notes

  • Checkout customization is fully controlled by the merchant
  • Flex does not automatically change checkout order
  • Results may vary depending on store configuration and customer behavior

​
