Billing failures can be a lead contributor to churn - which is why we've created a simple user flow to ensure your customers can keep their payment methods up to date.

Written by Karin Brashears

There are three main reasons why recurring customer orders may fail:

  1. Payment Method Failures

  2. Shopify Errors

  3. Inventory Issues

In this article, we’ll focus on the first two causes — Payment Method Failures and Shopify Errors.

Adding A New Payment Method

Stay now allows merchants to give customers a simpler way to update their payment method — without navigating through Shopify’s standard flow.

Benefits of This Update

This improved flow helps customers succeed in several ways:

  • Seamless Experience: Customers can securely add a new payment method directly within the Stay portal.

  • Fewer Steps: No need to go through Shopify’s “Update Payment Method” email flow.

  • Shop Pay Workaround: Bypasses common Shop Pay errors by generating a new, valid payment method ID.

How It Works for Customers

  1. Access the Customer Portal
    Customers can open the Edit Payment Method modal in their portal.

  1. Add a New Payment Method
    By clicking “Add New Payment Method” button, the customer will be directed to a secure Add Credit Card form.

    • They can enter their new card details.

  2. Automatic Update and Retry
    Once saved, Stay AI automatically updates the payment method ID on the subscription.
    The customer’s next billing attempt will then be charged to the newly added credit card.
