Why we built CashSDK

Every app that charges money eventually hits the same wall: StoreKit and Play Billing give you receipts, but not answers. Is this user really subscribed? Did that renewal go through? What's our actual MRR this week?

The hosted-vendor tax

The common fix is a hosted vendor that sits between your app and the stores. It works - until you realize your most sensitive data, your revenue, now lives in someone else's database, and you're paying a percentage of every sale for the privilege.

For a lot of teams that's a fine trade. For many others - regulated industries, data-residency requirements, or simply thin margins - it isn't.

A different default

CashSDK is the same capability set, built for coding agents to integrate end-to-end in under an hour. Drop-in SDKs, server-side validation, remote paywalls, and analytics - with your revenue data always yours.

  • Own your purchase data end to end
  • One-click full export on every plan - never sold or shared
  • Capped pricing: free to $5,000/mo, then 1%, hard-capped at $999/mo

You shouldn't have to choose between shipping fast and owning your data. That's the bet we're making.
