What is upsell?
Upsell products are items that you recommend as alternatives to the product a customer is viewing. These alternatives are usually of higher quality, more feature-rich, or more expensive.
What is Cross-sell?
Cross-sell products are complementary items suggested to the customer at the shopping cart stage, based on the products they have already added to the cart.
