Stop checkout when shipping and billing dont match

Topic summary

Request to block checkout when a customer’s shipping and billing addresses don’t match, seeking a specific app to enforce this.

Current guidance:

  • No app was identified; one responder is unsure an app can enforce this reliably.
  • If using Shopify Plus (Shopify’s enterprise tier), this can be implemented by customizing the checkout.liquid template (the file that controls checkout layout/logic).
  • If checkout.liquid isn’t visible in the theme editor, Shopify support can enable it for Plus stores.

Key terms:

  • Shopify Plus: an advanced, enterprise-level plan with deeper checkout customization.
  • checkout.liquid: a theme file allowing custom code/logic on the checkout page for Plus stores.

Outcome and status:

  • No concrete third‑party app solution was provided.
  • Action item: verify if the store is on Shopify Plus and explore checkout.liquid customization; contact Shopify to enable the file if needed.
  • Discussion remains open with unanswered question about non‑Plus app options.

What is the name of the application to download that will not allow customer to complete purchase if shipping and billing don’t match? I have seen other website not allow customer to move forward with checkout and would like to add this to my store.

I’m not 100% sure this can be done with an app. Wouldn’t be the first time I was wrong, though. However, if you’re on Plus you can certainly do it by customizing your checkout.liquid file in your theme. If you’re on Plus and don’t see the file in your theme editor, you can contact Shopify to enable it.
