How it sells itself

Back in Stock helps merchants recover lost sales from out-of-stock products. When an item is sold out, customers can enter their email to be notified the moment it becomes available again. The app automatically tracks inventory changes and sends restock emails without any manual work.

There's Stock Again lets customers subscribe to restock alerts for any out-of-stock product or variant. When inventory is replenished, subscribers automatically receive an email with a direct link to purchase, no need to do anything else. Setup takes minutes — add the widget to your store theme with no coding required. Monitor all subscriptions and sent notifications from a clean dashboard inside your Shopify admin.

Key points
  • Email notifications when out-of-stock products are restocked
  • Automatic inventory tracking with no manual setup required
  • Merchant dashboard showing waitlist signups for every product
  • Automatic email alerts when products are back in stock
  • No-code widget added to your store via theme app extension
  • Dashboard to track subscriptions and notifications sent
