The POS Product Variant Selection Popup in Odoo gives cashiers a simple way to manage products with multiple options. After selecting a product, a popup shows all available variants, such as size, color, design, model, or material. Staff can choose the required option without leaving the POS screen or searching through a long product list. This speeds up order processing and reduces the chance of adding the wrong item. It also keeps the sales process clear and organized. Retail businesses can serve customers faster while making sure every order includes the correct product combination and accurate variant details at checkout.
