One missing zero can publish a product far below cost — and you are legally bound to honor that price until someone notices. Product Sentinel is the guardian that prevents it. It monitors every product in real time, and the moment a price drops below cost it restores the correct value to your target margin and emails you what happened. It also warns you before low stock becomes a stockout. You set the thresholds; the app watches quietly in the background and only speaks up when it matters.

• Detects below-cost prices in real time and restores them automatically
• Reverts to your correct price and target margin — never a guessed value
• Low-stock alerts with thresholds you control, so stockouts do not surprise you
• Email notifications plus a clear log of every price and stock action taken
• One-click catalog sync and a simple dashboard — no setup or code required
