Is the payment system PCI compliant?

Yes. We use tokenized payments through Stripe Elements or PayPal SDK, which means sensitive card data never touches your servers, ensuring PCI DSS compliance.

Can I add more payment providers later?

The abstraction layer is designed for extensibility. Adding a new provider means implementing a standard interface without touching existing code.

How are failed subscription payments handled?

The system includes configurable dunning logic that retries failed charges, notifies customers, and can pause or cancel subscriptions after a set number of failures.
