Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMany Shopify themes only check the default location for inventory, causing products to appear "Sold Out" even when stock exists in other warehouses. iyosa solves this by using total available stock data across all locations.
Sold-out products push shoppers away, and they are easy to miss. Shelfback watches your inventory and keeps out-of-stock products from cluttering your collections, so shoppers see what they can buy. It never drafts, hides, or deletes products, so your product pages and URLs stay intact.
- Accurate multi-location stock visibility, fixing false "sold out" issues.
- Automatically sort collections by total real-time inventory count.
- Add dynamic "Low Stock" or "Hurry!" badges to create social proof urgency.
- Webhook-based automation ensures stock data is always current instantly.
- Automatically move out-of-stock products to the bottom of your collections
- Email alerts when a product sells out, plus an optional daily summary
- See which top-sellers are low or out of stock, ranked by restock priority
- Exclude any product, tag, vendor, or product type so it is never moved
