Set an alert level for each product whose stock you track, then use Inventory and your notifications to follow what needs restocking.
Step 1. Set the low-stock level
In the product form, enter the number in Low Stock Alert and save. For per-variant stock, the level applies to each variant. For weight or volume products, use the unit shown in the label.
To set a different level for one branch or warehouse, open Inventory and press the bell button, Alert level, on that line. In Warn me when available falls to, write the number and press Save. Leave it empty to stop warning at that place.
Step 2. Find what is running low
Check the stock column in Products: a low count turns red with a warning triangle. In Inventory, the Low Stock Alerts card counts them, and setting Stock status to Low stock or Out of stock lists them. Products set to No tracking never warn.
Step 3. Open inventory notifications
Press the notification bell in the dashboard to read the stock alerts you received. Check the product name and quantity mentioned, then open Inventory to see the current number.
Step 4. Choose how alerts reach you
Open Settings & Configurations, then the Notifications tab. Under Inventory, turn the low-stock and out-of-stock alerts on or off for Dashboard and Email. Wait for the message that the change was saved.
Hint: the business owner also sees Stock alerts for the whole shop at the top of the Inventory card. Turning it off stops these alerts at every branch, for everyone, and the rows under it read Off for the whole shop.
Step 5. Update stock after restocking
Customers cannot buy a product when its tracked stock runs out, and your storefront shows it as out of stock. When more stock arrives, record it with Adjust stock, then check the product on your storefront.
Result
A product at or under its alert level shows red in Products, appears in Inventory under Low stock, and sends you an alert the way you chose.
