The Shopify low stock alerts app that prevents stockouts, not just reports them
Most Shopify low stock alert apps email you when a SKU dips below a threshold and stop there. Great — now you know you're already too late. Smart Restock watches your inventory across every location, alerts you before you actually sell out based on your real sales velocity, and drafts the reorder from the right supplier so all you have to do is click send.

Velocity-based Shopify low stock alerts
Set per-SKU or per-collection alert rules that trigger not just on quantity, but on days-of-cover. If a SKU is selling 12 units a week and you have 20 in stock, Smart Restock alerts you now — not when you hit an arbitrary floor of 5. Alerts land in email, Slack, or as a daily digest.
Alert thresholds can vary by Shopify location: your flagship store might need 14 days of cover, your online-only warehouse 30, your seasonal pop-up 7. Set the rule once per location and Smart Restock does the rest.
Auto-drafted purchase orders
When an alert fires, Smart Restock drafts a purchase order to the supplier you normally reorder that SKU from, at the right quantity for the location that's low. You review, adjust, and send — or, for suppliers you trust, enable one-click auto-send.

Frequently asked questions
How are Shopify low stock alerts different from Shopify's built-in low stock report?
Shopify's report is a manual pull that shows current quantity below a threshold. Smart Restock alerts push to email/Slack in real time based on sales velocity, and drafts the reorder automatically.
Can I set different alert thresholds per location?
Yes. Threshold, cover-days target, and reorder quantity can all vary per Shopify location and per supplier.
Do alerts include variants, or just parent products?
Alerts run per variant, so a size Medium going low won't get hidden behind a healthy Small and Large.
