Instant In-Stock Sorting for Collection Pages
The Opportunity
An app that adds an 'In stock' option to Shopify collection sort dropdowns so shoppers can quickly prioritize available items. This is especially useful for catalog-heavy stores where availability changes often and customers want to avoid out-of-stock products.
"Merchants want a native, customer-facing way to sort products by inventory availability directly in the collection sorting dropdown."
Market Validation
Detailed Analysis
Proposed Solution
Provide a theme app extension or storefront filter enhancement that adds an 'In stock' sort/filter option, dynamically sorting collection results by variant/product availability and optionally pushing out-of-stock items to the bottom.
Target Audience
Shopify merchants with large catalogs, hobby shops, parts suppliers, and stores with frequent stock fluctuations
Competitive Landscape
Some filter/search apps and merchandising apps offer stock-aware sorting, but many merchants may not have this as a simple built-in dropdown option.
Implementation Notes
Build a theme app extension or storefront script-free integration that injects an additional sort option into collection controls, then map the sort to inventory status using product/variant availability and optionally metafields for backorder/preorder logic. Must support different theme structures, preserve existing sort behavior, and avoid slowing collection page rendering.
