Up-selling is a sales strategy that involves encouraging customers to purchase a more expensive, upgraded, or premium version of the product or service they are considering. The goal of up-selling is to increase the overall value of the sale by offering customers enhanced features, benefits, or services that better meet their needs. For example, a salesperson might suggest a higher-tier phone with more storage capacity or an extended service plan. Up-selling can lead to increased revenue, improved customer satisfaction, and stronger customer relationships by ensuring that customers receive the best possible solution for their needs.
