Crate is a warehouse management system for businesses that ship from one or more warehouses. It keeps a single source of truth for stock across all locations and syncs those quantities to Shopify, so your storefront reflects what is on hand. When an order comes in, Crate reserves the items to prevent overselling and releases them if the order is cancelled. Organize each warehouse into zones, aisles, racks, and bins, receive stock against purchase orders, track batches and expiry dates,

• Real-time inventory sync between your warehouses and Shopify locations.
• Automatic stock reservation on new orders to prevent overselling.
• Multi-warehouse stock with zones, aisles, racks, and bin-level locations.
• Receive stock against purchase orders with goods receipts and supplier records.
