Step-by-step explanation:
An upsell to a California veggie pizza may include offering additional toppings, a larger size, or a premium crust as part of the purchase. Upselling is a sales technique where a seller induces the customer to purchase more expensive items, upgrades, or other add-ons in an attempt to make a more profitable sale. For a California veggie pizza, this could be suggesting a gluten-free or whole wheat crust, premium cheese options like goat cheese or feta, or exclusive gourmet toppings such as artichoke hearts, sun-dried tomatoes, or avocado. Upselling aims to create more value for the customer, while also increasing the business's revenue.
