Upselling

Upselling is a sales technique whereby the seller tries to convince the customer to purchase a product that is more expensive than the one chosen initially. The upsell is usually done when the customer is on a product page and aims to make the sale more profitable for the seller. In  e-commerce websites, this sales strategy usually refers to adding more expensive products in the cart, while in SaaS websites, customers are encouraged to purchase add-ons or product upgrades.
