How Do You Manage Subscription Metrics Across Different Platforms?

I use Lemon Squeezy, and I've managed to tackle this through webhooks. What I do is normalize all the subscription events into my own database so that I can calculate MRR, churn, and LTV directly. I even built a simple internal admin dashboard that shows me consolidated metrics, rather than depending solely on the provider's analytics. It's manageable with a single provider, but I imagine it gets way more complicated when you mix in different platforms like Stripe or the App Store.

The challenge isn't just about gathering data from various providers; it’s really about normalizing subscription events. Each provider, like Stripe, the App Store, and Google Play, has their own definitions for churn, trials, renewals, and refunds. Many teams either create an in-house metrics layer or opt for tools like RevenueCat, Baremetrics, or ChartMogul. If you're developing a solution, the key value would lie in clean event normalization and consistent definitions for MRR, rather than just offering dashboards.
