Guides
Every guide here starts with what Shopify already gives you for free, says where that stops, and only then explains what an app adds. If the free route covers your case, the guide says so.
Low stock alerts
Shopify Flow sends low stock emails for free on every plan. Here is how to set it up in about five minutes, and the four situations where a fixed threshold quietly stops working.
Reorder points
The reorder point formula in one line, plus exactly which Shopify report gives you each input. Includes safety stock, why lead time is the number people get wrong, and what to do when demand is seasonal.
Multi-location
Shopify totals your stock across locations, and that total is what most alerts look at. Here is why the total hides the stockout that costs you the sale, and how to get alerts that know which shelf is empty.
Choosing a tool
Two Shopify features with almost the same name do opposite jobs. One emails you so you can reorder, the other emails your customer so they can buy. Here is how to tell which you need, and what each one costs.
StockPilot emails you when a variant drops below the level you set, per location, based on real sales velocity. Free plan, then $9/month.
