Shopify low stock alerts, without setting a threshold for every product

Running out of stock is one of the quietest ways a Shopify store loses money. A product sells well, then it hits zero, and the sales simply stop while your attention is somewhere else. Most low stock apps promise to warn you, but they ask you to do the hard part first: pick a reorder number for every product you carry. Stock Scout takes a different route.

The Stock Scout dashboard, sorted by how soon each product runs out.

Why fixed thresholds do not work well

A threshold is a single number, but inventory is not a single speed problem. Say you set an alert at five units. For a product that sells eight a day, five units is already too late. For a product that sells one a month, five units is months of stock and the alert is just noise. One number cannot be right for both, so you end up with warnings that fire too late on your best sellers and cry wolf on your slow ones.

And that is before the work of choosing a number for hundreds of products, then keeping every one of them updated as sales shift through the year.

Days of cover, not a magic number

Stock Scout reads your recent sales, works out how fast each product actually sells (its daily sales velocity), then calculates how many days of stock you have left at that pace. That figure is called days of cover, and it is the thing that actually tells you whether to worry.

A product with two units left and strong sales might have two days of cover. A product with two units left and almost no sales might have two months. Stock Scout treats them differently, because they are different. The thresholds are your sales data, so there is nothing to set up.

Alerts ranked by how soon you run out

The dashboard lists your products by time to sellout, most urgent first, so the items about to cost you sales sit right at the top. Anything already out of stock that was selling well gets flagged clearly, so you can reorder before the gap widens.

Quiet by design

A good alert is one you can trust, which means it has to stay silent when nothing is wrong. Stock Scout does not fire on slow sellers that happen to be low, and it holds back on products without enough recent sales to judge, because a single order is not a trend. A daily email digest arrives only when something is genuinely out of stock or at risk. When your store is healthy, you hear nothing at all.

Read only, so it is safe to try

Stock Scout never changes your products, your inventory, or your theme. It reads only what it needs to do its job, and it does not touch any customer information. You can install it, watch it work on your own catalog, and uninstall it with nothing left behind.

What it costs

Stock Scout is $9 per month with a 14 day free trial, so you can see it flag real products in your own store before you pay anything.
