Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Grow because paywalls and upgrade flows monetize existing users after the product is live. Lifecycle covers trial endings, plan upgrades, and retention-oriented upsell surfaces inside the product.
Where it fits
Before coding, stress-test how tier limits will appear on a pricing screen users see at signup.
Spec modal hierarchy, primary CTA, and objection handling before your agent implements the paywall component.
Redesign the trial-expired paywall and plan comparison strip ahead of a conversion experiment.
How it compares
Conversion-focused paywall design skill—not a Stripe billing integration or generic landing-page SEO pack.
