What problem does it solve? Choosing between subscription billing platforms like RevenueCat, Stripe Billing, Paddle, Lemon Squeezy, Chargebee, and Recurly is confusing because each differs in platform support, pricing model, tax handling, and feature depth. This Skill removes the guesswork by comparing them side by side and recommending the right fit. ## Core Features & Use Cases - Service Catalog: A structured comparison table of six subscription platforms covering platform support, pricing, core features, and ideal use cases. - Decision Tree: A platform-first decision flow (mobile app, web SaaS, or hybrid) that narrows down to a concrete recommendation. - Feature Matrix: Head-to-head comparison of Apple IAP integration, Google Play integration, Merchant of Record tax handling, proration, dunning, custom UI, and Korean payment support. - Use Case: A solo developer building an iOS/Android app with subscriptions asks which billing service to use, and receives a RevenueCat recommendation with reasoning, plus a Stripe + RevenueCat combination if they also sell on the web. ## Quick Start Ask which subscription management service to use for your product, mentioning your platform (mobile app, web SaaS, or both) and whether you want automatic tax handling.
