About the Cart Reserve

Cart Reserve prevents overselling by instantly locking inventory when customers add items to their cart. This real-time reservation system protects your stock during flash sales, product drops, and high-traffic periods. The app uses AI-powered fraud detection to identify and block bots and suspicious sessions, ensuring fair access for genuine customers. When cart sessions expire, reserved inventory automatically releases back into your available stock without manual intervention. Customize reservation duration and quantity limits per product or variant. The live dashboard provides real-time analytics on active reservations and current availability. Additional protection includes IP blocking, country restrictions, and AI-generated insights to help you understand buying patterns and potential threats to your inventory accuracy.
