POS Order Discount in Odoo makes it easy for retailers to apply discounts on the full customer order directly from the POS screen. Instead of changing each product price manually, the cashier can add a fixed or percentage discount in a few clicks. This saves time during billing, reduces mistakes, and keeps the checkout process smooth. Store owners can manage offers, seasonal sales, special customer discounts, and promotional deals more clearly. It also gives better control over pricing and helps maintain accurate sales records for daily retail business operations too.
