## What is Recurring Billing?

Recurring billing is a payment model where customers are charged automatically at regular intervals for goods or services. This model is especially popular among subscription-based businesses such as streaming services, gym memberships, and SaaS products. The major advantage of recurring billing is the ability to ensure a predictable revenue stream while enhancing customer convenience.

- **Scalability**: Businesses can scale operations without manual billing processes.

### Examples of Recurring Billing
- **Netflix** bills users monthly for access to its streaming service.
- **Adobe Creative Cloud** offers a subscription model for its suite of creative tools.
- **Amazon Prime** charges annually or monthly for access to exclusive content and services.

Payment SDK documentation is a critical resource for developers integrating payment functionalities into their applications. A comprehensive SDK documentation provides detailed instructions, code examples, and best practices to ensure smooth integration and functionality.

### Key Components of Payment SDK Documentation
