Introduction
Billing SDK that runs inside your application
BillSDK is a billing engine that runs inside your application. You define plans and features in code, integrate with Stripe (or any payment provider), and ship billing in minutes.
Why BillSDK
Billing SaaS platforms (Stripe Billing, Chargebee) lock you into their ecosystem, charge a percentage of your revenue, and run your billing logic on their servers.
Building billing yourself takes months and every edge case (trials, proration, failures) costs you revenue or angry customers.
