A user must make a purchase to engage in which stages of the customer funnel?

Advocacy and Loyalty stages inherently require a prior purchase. In the Advocacy stage, customers share positive experiences and recommend a product or service, which presupposes they have used or owned it. Similarly, the Loyalty stage signifies repeat purchases and ongoing engagement, directly stemming from initial and subsequent transactions. The Purchase stage is where the transaction occurs, not a stage requiring a prior purchase to engage in it. Interest, Awareness, and Consideration are earlier stages where potential customers are learning about or evaluating a product, and do not involve a purchase.
