Kill Bill Documentation

Kill Bill is an open-source, cloud-native, and multi-tenant subscription billing and payments infrastructure. It allows companies to manage subscriptions, generate invoices, and process payments while maintaining full control over their billing stack through a flexible and extensible plugin architecture.

Aviate is the enterprise extension for Kill Bill. It adds premium capabilities including metering, wallet management, coupons, advanced tax handling, and custom invoice sequencing.

To quickly explore the core features of Kill Bill, you can install the platform locally using Docker. This is the recommended path for developers to get started with the system.

Kill Bill provides a web-based administration interface called Kaui, which allows users to manage accounts, subscriptions, and invoices without interacting directly with the API.
