Frequently asked questions

What counts as tracked revenue?+

The gross value of the Production purchases CashSDK validates for you in a month (Sandbox never counts). That's the MTR in the formula.

Do you take a percentage of my revenue forever?+

No. You pay 1% only on revenue above $5,000/month, and it's hard-capped at $999. Past ~$105K MTR your bill is flat $999 no matter how big you get — that's where the 1% players run into five figures.

What's the founding offer?+

The first 500 workspaces to add a payment method lock in a 0.8% rate — for the life of the account. It never goes up.

What happens if a payment fails?+

We never cut off your money path — your users keep purchasing and their entitlements keep resolving while you update your card. We collect through normal dunning, never by disabling your revenue.

I'm switching from RevenueCat / Superwall / Adapty. What do I get?+

A free, agent-run migration and 6 months on us. We import your history in shadow mode — it never inflates your bill — and you only start paying after you've cut over.
