The Discount in Purchase Order Line feature in Odoo lets users apply specific discounts directly on each product line of a purchase order. Users can enter a discount percentage or amount for individual items, making it easier to manage supplier offers and negotiate better deals. This feature helps control purchase costs, improves accuracy in pricing, and ensures that the system reflects the actual payable amount. With this function, businesses can maintain clear records of discounts received and simplify accounting entries. Odoo users can easily view, edit, and track these discounts without needing extra customizations or manual calculations.
