About this app

Overselling kills drops. You sell 500 units, refund 80, and 80 customers turn on you publicly. Cart Reserve fixes it at the source: the moment a shopper adds an item, that unit is held for them — and a tamper-proof checkout keeps it held, so it can't be bypassed by blocking scripts, forging cart tokens, or hitting the API directly. AI scores every cart-add and blocks bots before they drain stock. Expired carts auto-release inventory — no manual cleanup. Set per-product hold times, watch live act
