Monitor inventory in real time and catch anomalies. Auto-pause products before they oversell.
Overselling usually isn't caused by running out of stock. It happens when a number goes wrong quietly, so you hear about it from a customer instead of your store. Guardrail watches your inventory as it changes and flags anomalies like negative stock, low buffers, and sudden jumps. It emails you when something looks wrong. You can set a safety buffer so a product is paused from sale before it oversells. It never changes your stock counts, and it deletes your data when you uninstall.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Guardrail on a store, it is there.
