Shopify Customer Accounts and Checkout Page Upgrades: What to Do Now

Shopify’s deadlines for replacing legacy Thank you and Order status pages have passed: August 28, 2025 for Plus and August 26, 2026 for non-Plus stores. Shopify began automatic upgrades in January 2026. Review the configuration currently active on your store and any scripts, pixels, and app integrations that need follow-up. Across 10 million+ Shopify orders, 5.2% are edited after checkout (Revize, 2026).

Customer accounts are a separate migration. Shopify has deprecated Legacy Customer Accounts and recommends upgrading to the latest customer accounts, but its current Help Center does not list a retirement date for Legacy accounts. The new accounts use email verification codes by default and support app-based customizations.

Checkout and Order status page deadlines (both passed):

  • August 28, 2025: Shopify Plus Thank you and Order status pages.
  • August 26, 2026: Non-Plus Thank you and Order status pages.

These dates cover checkout pages, not the Legacy Customer Accounts upgrade. Check your store’s current checkout configuration and Shopify notices to confirm what has been upgraded.

This guide separates the checkout-page deadlines from the customer-account upgrade and gives current steps for each:

  • The Rationale: Why Shopify is making this change.
  • Legacy vs. New: Key differences impacting your store and customers.
  • Key Benefits: Why migrating offers tangible advantages.
  • The Migration Process: A simplified step-by-step approach.
  • Potential Challenges: What to consider and prepare for (Customization, Apps, Tracking).
  • App Readiness: How tools like Revize - Order Editing fit into the new ecosystem.
  • Best Practices: Tips for a seamless switch.
  • Current status: Which deadlines have passed and what remains optional or plan-dependent.

Let’s explore the details.

1. Why is Shopify Moving to New Customer Accounts?

This transition is a strategic move by Shopify aimed at significant platform improvements:

  • Passwordless sign-in: New Customer Accounts use email and a one-time passcode by default; customers can also use Google or Facebook sign-in when enabled.
  • Hosted account experience: New Customer Accounts do not use the Legacy account Liquid templates. Review the available editor settings and extensions for your store.
  • B2B account support: New Customer Accounts support Shopify’s current native B2B account experience. Review plan requirements and test company access before upgrading.
  • Account features: New Customer Accounts support app extensions and customer features such as self-serve returns and store credit.
  • App and identity-provider options: Apps can add supported account features, and stores can connect their own identity provider.
  • Part of Broader Modernization: This change aligns with Shopify’s overall move towards more secure and extensible platform components, similar to the shift towards Checkout Extensibility for checkout pages (which has its own related deadlines and processes for replacing checkout.liquid and scripts).

2. Legacy vs. New Customer Accounts: Understanding the Critical Differences

Knowing these distinctions is crucial for planning your migration:

Feature Legacy Customer Accounts New Customer Accounts What This Means For You
Login Method Email and password; Shopify Plus stores can use Multipass and other configured identity options. Email and one-time passcode by default; Google/Facebook sign-in or a connected identity provider can be enabled. Existing Multipass integrations on Plus continue to work after upgrade. Confirm the login and identity-provider setup your customers will use.
Account Creation Customers sign in with credentials for their existing account. Customers sign in with an email verification code or an enabled sign-in option. Test the sign-in and account-creation flow that is active in your store.
B2B Compatibility Legacy accounts do not support Shopify’s current native B2B customer-account experience. New Customer Accounts support native Shopify B2B features where available on the plan. Check the B2B feature matrix and customer-account requirements for your plan.
Customization Legacy account pages can include Liquid templates and theme customizations. The hosted account pages use editor settings and supported app extensions; Legacy Liquid templates do not transfer. Inventory customizations and confirm an app or extension supports the needed account page.
Branding Account pages can use theme-based legacy customization. Customize available brand settings in the checkout and accounts editor; the sign-in page has limited extension options. Preview and publish the account configuration before upgrading.
Self-Serve Returns Depends on the legacy setup and installed apps. Customers can start a return from their account when the feature is configured. Review return eligibility and settings in your store.
Store Credit and Subscriptions Feature availability depends on the legacy setup and apps. Customers can view and use store credit; subscription actions depend on the installed app. Check the current feature and app requirements.
Apps Apps may rely on Legacy templates or older APIs. Apps can add supported features through customer-account extensions. Confirm each app’s current support for the customer accounts version you use.
Pixels and Events Legacy custom scripts may track account-page activity. Event availability depends on Shopify’s current pixel APIs and the account page. Check Shopify’s current pixel documentation and test each required event.
Shopify Flow Legacy-account triggers and filters may be used by existing workflows. Workflows based on Legacy Customer Accounts are not supported in the new accounts experience. Audit those workflows and replace them where a supported trigger exists.
Account Domains Legacy account pages use the store’s theme and domain setup. A single customer-account domain is used across markets; you cannot set a separate account domain per market. Check the account domain and redirect behavior across your markets.

3. Benefits of Upgrading Customer Accounts

New Customer Accounts change the sign-in method and available app features. Review these options before upgrading:

  • Fortified Security: Benefit from modern, passwordless authentication.
  • Smoother Logins: Offer a faster, simpler login experience, especially on mobile.
  • Hosted account pages: Use Shopify’s current account experience rather than your Legacy account Liquid templates.
  • Native B2B support: Use Shopify B2B features with New Customer Accounts where available on your plan.
  • Self-service features: Customers can start returns and view store credit from their account; app extensions can add supported account features.
  • Future-Ready Platform: Ensure compatibility with new Shopify features built on the modern architecture.
  • App extensions: Add loyalty, subscriptions, and other account features through apps that support Customer Account Extensions.

4. Your Migration Roadmap: Steps to Transition

Shopify provides tools for this process, but careful preparation is key:

  1. Check the current checkout configuration. The Plus and non-Plus Thank you and Order status page deadlines have passed. Review Shopify’s notices and confirm which version is active.

  2. Review customer accounts separately:

    • Legacy customizations: List account-page Liquid, sign-in, and registration customizations that will not transfer.
    • App compatibility: Check each app’s current documentation for support for New Customer Accounts and its customer-account extensions.
    • Custom code and pixels: Identify login, registration, and account-page code or events that need a supported replacement.
    • Shopify Flow: Find workflows that use Legacy Customer Accounts triggers or filters; those are not supported in the new accounts experience.
    • Account domain: Confirm the single account domain works for your markets.
    • Identity provider: Test each sign-in route you offer and check redirects from custom login pages. Shopify’s customer-account upgrade guide documents the current identity-provider and rollback behavior.
  3. Preview and test the new account experience. Sign in using each option you offer and test app features, B2B access, and customer account links.

  4. Communicate the sign-in change. Explain email verification codes or any social or identity-provider sign-in you have enabled.

  5. Upgrade when ready. In Shopify Admin, go to Settings → Customer accounts and click Upgrade. Publish the account configuration and test the customer-facing links.

  6. Test after the upgrade. Check sign-in, order history, returns, store credit, app extensions, and the customer account domain.

  7. Know the rollback window. Shopify allows you to revert to Legacy Customer Accounts within 30 days after upgrading. Treat this as a temporary troubleshooting option, and verify the current steps in Shopify’s Help Center.

Always consult the official Shopify Help Center for the latest detailed migration instructions.

5. Potential Challenges & Considerations

Be prepared for these common points:

  • Loss of Liquid Customizations: Highly styled or feature-rich custom account pages will look different. Prepare: Plan to use standard styling or explore Customer Account Extensions. Adjust expectations for visual control.
  • App Incompatibility: An incompatible app can disrupt functionality. Prepare: Rigorous auditing and developer communication before migrating are essential. Have alternatives ready if needed.
  • Identity-provider setup: Test custom login entry points and account redirects alongside the default email-code flow.
  • Legacy event tracking: Test any required account-page events against the current pixel APIs instead of assuming legacy scripts carry over.
  • Shopify Flow Adjustments: Automations tied to classic account events might need rebuilding. Prepare: Test relevant Flows post-migration.
  • Account domains: A separate customer-account domain per market is not supported; review the domain customers will use across markets.
  • Customer Adaptation: Some customers may need guidance on the new login method. Prepare: Clear communication is key.

6. Post-Purchase Editing and Customer Accounts

Customer-account upgrades and post-purchase order editing are separate features. Revize provides customer self-service changes before fulfillment through its order-status-page portal or an Edit Order link in the confirmation email. Test both entry points alongside the account upgrade, and confirm the merchant-set edit window and fulfillment workflow.

Product switching, add-on products, and store-credit refunds require Revize Pro. Staff-side order editing is in development.

7. Best Practices for a Smooth Transition

  • Review your current setup: The checkout-page deadlines have passed; account upgrades remain a separate decision.
  • Document Your Audit: Keep track of app compatibility, developer contacts, and theme checks.
  • Test Rigorously: Use a development/staging store for initial migration tests if possible. Test all critical user journeys.
  • Communicate Clearly & Often: Inform your team and customers well in advance. Explain the login change simply.
  • Backup Your Store: Standard best practice before major changes.
  • Monitor Post-Launch: Watch analytics and support channels closely after the switch.
  • Seek Expert Help if Needed: Engage a Shopify Partner/Agency for complex setups (heavy customization, Multipass) or if you need expert guidance.

8. Understanding the Importance of the Deadlines

The August 28, 2025 Plus deadline and August 26, 2026 non-Plus deadline apply to Thank you and Order status pages. Legacy Customer Accounts are deprecated, but Shopify’s current Help Center does not publish a retirement date for them. When planning an account upgrade, consider:

  • Potential Disruption: Rushing the process increases the chance of errors or overlooked compatibility issues.
  • Legacy templates: Liquid customizations do not transfer and need a supported replacement.
  • Feature requirements: New Customer Accounts are required for Shopify’s native B2B account experience.
  • Upgrade timing: Choose a time to test account links, app extensions, and sign-in instructions with your team.

Planning and migrating proactively ensures a smoother transition on your terms.

Conclusion: Prepare Your Store for the Future

Shopify has deprecated Legacy Customer Accounts and recommends upgrading, but its current Help Center does not give a retirement date. Review the new account experience, test your apps and customer links, and upgrade when your store is ready.

The upgrade involves checking Liquid customizations, account extensions, identity providers, domains, and workflows. Assign an owner to each integration and keep the tested account links and sign-in instructions in your rollout notes.

Treat the customer-account upgrade as separate from the checkout-page deadlines, which have already passed. Audit your setup, communicate the sign-in change, and test the configuration before publishing it.

If you use a post-purchase editing app, verify where customers open its portal and which features are eligible in your store. Revize supports customer edits through the order status page or a confirmation-email link; product switching and add-ons require Pro.

Review the current customer-account configuration, confirm the upgrade and rollback steps in Shopify Help Center, and test customer access after publishing.
