What is upsell and cross-sell?

Upsell — is a sales technique where the customer is offered to buy a more expensive or upgraded version of the product than the one they initially intended to purchase. For example, when buying a laptop, suggest a model with a more powerful processor or larger memory capacity.

Cross-sell — is an offer of related products or services that complement the main product. For example, when buying a smartphone, suggest purchasing a case, a protective glass, or headphones.

Both techniques aim to increase the average check and improve the user experience through relevant offers.
