How should a free tool introduce the paid product without feeling like a trap?

Finish the free task clearly, then offer a next step that fits a recognizable situation. Someone planning a product launch may want managed accounts; someone checking a friend’s profile may not. Give the offer enough context for the user to self-select.

Do not relabel the free result as unavailable just to force a purchase. Track the qualified path into the paid workflow while preserving the tool’s other useful roles. A free audience can include future customers, operators and people who will never need the paid product.
