Upselling is a sales technique whereby a seller induces the customer to purchase more expensive items, upgrades or other add-ons in an attempt to make a more profitable sale. While it usually involves marketing more profitable services or products, it can be simply exposing the customer to other options that were perhaps not considered. A different technique is cross-selling in which a seller tries to sell something else. In practice, large businesses usually combine upselling and cross-selling to maximize profit. In doing so, an organization must ensure that its relationship with the client is not disrupted.
