Beyond restock alerts, the app also supports abandoned cart recovery, helping you bring back customers who left without completing their purchase and maximize your store’s revenue without increasing ad spend. Whether you're running a growing Shopify store, dropshipping business, or Shopify Plus brand, Back in Stock Notify Pro helps you recover lost sales, increase conversions, capture demand, and build a high-intent subscriber base — all from one powerful app.

Why Shopify Stores Lose Sales When Products Are Out of Stock

When products show “Sold Out” on a Shopify store, customers leave — and most never return.

✖ Lost high-intent buyers ready to purchase
✖ SEO and ad traffic wasted on unavailable products
✖ No native Shopify back-in-stock notifications

Shopify doesn’t automatically notify customers when products restock.

That’s where Back in Stock Notify Pro helps merchants recover lost sales automatically.
