The Product Stock Notification Alert extension helps you capture lost sales by allowing customers to subscribe for restock alerts on out-of-stock products. When a product becomes available again, customers receive automatic email notifications and optional SMS alerts, encouraging them to return and complete their purchase.

Instead of losing potential buyers when a product is unavailable, your store can collect demand, notify interested customers, and increase conversion rates automatically.

This extension intelligently replaces the "Add to Cart" button with a "Notify Me" button when a product or product option is out of stock. Customers can subscribe easily, while store owners gain valuable insights into product demand trends.

Trusted by 900+ OpenCart stores worldwide, this extension is designed to improve customer engagement, increase conversions, and provide powerful demand analytics.

If you need both Add to Cart and Notify Me functionalities for out-of-stock products, customization can be provided. Contact support for more details.
