Subtotal Connect

Subtotal Connect makes it simple for merchants to add account-linking buttons to their Shopify store without any custom development. The app provides ready-to-use theme blocks that let you place "Link account" buttons on any page of your storefront. These buttons launch the Subtotal Link flow, allowing shoppers to securely connect their retailer accounts. Customers can easily manage their connections, disconnect, or reauthenticate whenever needed. This solution helps merchants reliably initiate secure account linking while keeping everything consistent and easy to manage directly from Shopify.
