Catch the details that matter

A clearer path from checkout to delivery.

Give customers a chance to resolve address issues while they are still at checkout.

01 / ADDRESS CORRECTIONS

Let customers get it right.

Present suggested address corrections for customers to review. When a suggestion is accepted, Addrexx updates the Shopify shipping address.

02 / MISSING APARTMENTS

Catch a missing unit.

For U.S. addresses, flag when an apartment, suite, or unit may be required and prompt customers to add the missing detail.

03 / SHOP PAY

Keep express checkout covered.

With the Addrexx app block enabled in Shop Pay, validate the default shipping address on page load and check changes to saved addresses.
