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.
Customer attention is the lifeblood of your business. Don't waste that precious resource by showing customers pages of sold out products or by scrounging for back-in-stock emails on products that are never going to be replenished. Take a different approach. Use ZeroOut to hide out-of-stock products, strategically collect back-in-stock emails, and ensure you always have inventory to make the sale.
- 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.
- Hide out of stock products so customers don't see what they can't buy
- Collect back-in-stock emails on items temporarily out-of-stock
- Low-stock alerts so you can replenish inventory without interrupting sales
