    FAQ

    Cart Reserve — frequently asked questions.

    What is Cart Reserve on Shopify?
    Cart Reserve is a Shopify app in the Inventory optimization category. Overselling kills drops. You sell 500 units, refund 80, and 80 customers go angry on Twitter. Cart Reserve fixes this at the source: the second a shopper adds an item, we hold that unit for them. Our AI scores every cart-add and blocks bots before they drain your stock. Expired carts release inventory automatically — no manual cleanup. Set per-product hold times, watch live activity, and block traffic by IP or country. Built for stores running flash sales, drops, and limited releases. It averages 5.00 out of 5 across 1 merchant reviews on the Shopify App Store.
