The goal of upselling is to increase revenue per customer by encouraging customers to spend more money on additional products or services. It can be a powerful strategy for businesses, as it allows them to maximize revenue from existing customers, rather than relying solely on new customer acquisition.However, it's important for businesses to use upselling ethically and avoid being pushy or aggressive, as this can harm the customer experience and damage the business's reputation.
