The Purchase Multi Shipment app in Odoo helps you manage multiple deliveries for a single purchase order. Sometimes, vendors send items in parts instead of one full delivery. With this app, you can create and track each shipment separately while keeping them linked to the same purchase order. It gives you better control over received goods, delivery dates, and pending items. You can also generate separate receipts and keep records of each shipment. This is useful when handling large orders, backorders, or partial deliveries. It improves accuracy and makes the purchase-receiving process more organized and clear.
