See every featureAdStockGuard stops you from paying for ads that lead shoppers to sold-out products. It monitors your store's inventory and automatically pauses the matching ads on Meta, Google, TikTok, and Pinterest the moment a product hits zero or a safety buffer you set. When you restock, it reactivates those ads automatically, so customers can buy again.
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.
- Automatically pause and resume Meta, Google, TikTok, and Pinterest ads.
- Set custom stock thresholds to pause ads before inventory hits zero.
- Track predicted stockout dates and daily sales velocity for every product.
- Real-time inventory monitoring across all your locations
- Alerts for negative stock, low buffers, jumps, and rapid swings
- Auto-pause a product before it oversells, reversible anytime
- Email alerts so you catch problems even when you're away
