Top 5 opportunities in this hub
Preorder Payment Method Lock for Out-of-Stock Items
A Shopify app that automatically restricts checkout payment methods based on inventory status, such as allowing only card payments when items are out of stock and being sold as preorder. This helps merchants control risk and streamline preorder handling without manual checkout workarounds.
Checkout Address Lock for Invoice-Based Stores
An app that removes or restricts checkout address editing and new-address entry for stores that invoice customers separately. It helps merchants keep shipping data consistent when the address must be controlled in an external invoicing system like Sage.
Checkout Custom Field Collectors
An app that lets merchants add one or more custom text fields directly on the Shopify checkout flow for collecting special instructions, personalization details, or order-specific notes. It can support validation, conditional display, and order tagging for easier fulfillment.
Checkout Block Rules by Order Source
A Shopify app that lets merchants conditionally show checkout or post-purchase content based on order source attributes like Buy Button, Draft Order, sales channel, checkout type, and source name. It would help stores personalize messages, offers, or compliance notices only for the right order origins.
Checkout Text Editor for Payment Section
An app that lets merchants customize the visible text in the payment section of checkout without editing theme code. It would provide a safe UI for modifying labels, helper text, and gateway-related copy across supported themes like Dawn.
