POS Margin Display in Odoo gives retailers a clear view of product profitability during every sale. Cashiers and managers can check the cost price, selling price, margin value, and margin percentage from the POS screen. This makes it easier to identify products with strong or weak profit before the order is confirmed. The feature supports better pricing decisions and keeps the sales team aware of profit on each item. It also reduces manual calculations and saves time during busy hours. Businesses can use this information to protect margins, review discounts, and maintain better control over daily Point of Sale transactions.
