Upselling & Cross-selling

Upselling is encouraging a customer to buy a more expensive version of the product they are considering, while Cross-selling is suggesting complementary products (e.g., 'Would you like fries with that?'). In e-commerce, these are implemented via 'Customers also bought' sections or pre-checkout add-ons. These strategies are essential for increasing Average Order Value (AOV) and customer lifetime value without increasing acquisition costs.
