AdStockGuard 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. AdStockGuard also shows how much ad budget you've protected and predicts each product's stockout date from its sales velocity.
