The Low Stock Warning extension, enhances inventory monitoring in OpenCart, by providing a controlled, intelligent notification system for low stock products.
Instead of sending repeated alerts for the same items, it ensures that administrators receive a single, clear, and actionable email notification per low-stock event.

This extension continuously monitors product inventory levels and triggers an email notification when stock falls below a defined threshold.
It is designed to eliminate notification spam while ensuring that critical stock shortages are never overlooked.

- Detects products where quantity <= threshold
- Sends one admin email listing of all such products
- Includes product_id, name, quantity
- Displays total products found
- Prevents repeated emails (send once until stock changes)
- Avoids duplicate notifications
- HTML email table
- Admin UI (enable/disable)
- Reset button (manual reset of low stock flag)
- Set stock threshold
- Auto Resets low stock when Stock Increases
- Product restocked then the flag reset
- If drops again, email sent again
