The Mass Purchase Order Send by Mail feature in Odoo helps you quickly send multiple purchase orders to vendors in just a few clicks. Instead of opening each order one by one, you can select several at once and send them all by email together. This saves time, especially when dealing with many orders. It's useful for companies that place frequent or bulk orders and want to keep their vendors informed without delays. The system automatically attaches the purchase order PDF and sends it to the vendor’s email. It helps ensure faster communication and smoother purchase operations.
