Lifetime Deal Access Drift Checker
A checker that verifies lifetime-deal buyers still have exactly the access they were promised after migrations, plan renames, and billing-system changes. It catches LTD buyers who are locked out, downgraded, or accidentally turned into subscription users.
🎯The Problem
A founder sold 300 lifetime deals during launch, then rebuilt pricing around monthly subscriptions. A year later, some LTD buyers are stuck on a deprecated plan, some lost a feature after a flag rename, and a few are being asked to subscribe again. The payment event happened once, so normal subscription dashboards do not keep screaming about it. The drift only appears when an annoyed lifetime customer emails support.
💡The Solution
Import the lifetime cohort from Stripe, Lemon Squeezy, AppSumo CSV, or a manual list, then compare each buyer against current app access rules. The checker flags missing lifetime flags, accidental subscription prompts, downgraded feature access, and duplicate billing records.
👥Target Users
Indie SaaS founders and small teams of 1-10 who sold AppSumo-style deals, early lifetime licenses, one-time plans, or founder passes.
