Upselling in retail is the practice of encouraging customers to purchase a higher-end or additional product than the one initially intended. Retailers employ various strategies, such as suggesting complementary items, highlighting premium features, or offering bundled deals, to entice customers to upgrade their purchase. Effective upselling not only increases the average transaction value but also enhances customer satisfaction by providing them with additional value or better options. This technique relies on understanding customer needs and preferences, enabling retailers to make relevant and appealing recommendations during the sales process.
