Kill Bill

Kill Bill is an open-source subscription billing and payments platform designed to manage payment infrastructure. It provides a comprehensive set of tools for handling recurring billing, financial reporting, and real-time analytics. The software is deployed as a server application and can be hosted on-premises or in the cloud, providing a foundation for organizations to scale their billing operations as their customer base grows.

The platform supports a wide range of business models for online organizations, including SaaS and e-commerce. It allows operators to maintain full control over their business and client data, which removes reliance on the uptime or processing speeds of third-party providers. Users can deploy the system via a one-click deployer for AWS or utilize hosted sandboxes and developer tools for initial testing and configuration.

Key features

• Support for multiple subscription billing models
• Management of trial periods and promotional discounts
• Real-time analytics and financial reporting tools
• Modular architecture to disable or replace specific functions
• Framework for system extensibility
• Deployment options for on-premises or cloud environments
• Apache License 2.0 open-source licensing

The software utilizes a modular design, meaning it does not function as a rigid all-in-one solution. This architecture enables organizations to integrate Kill Bill with existing internal systems or disable unnecessary components to streamline the workflow. Because the project is split across multiple repositories rather than a single monolithic codebase, it allows for more granular management of its various components and plugins. The system is designed to be introduced into one business area first and then migrated to others over time.

Kill Bill is intended for businesses that require a scalable billing stack with full control over their financial data and the flexibility to customize their payment infrastructure.
