Kill Bill

Kill Bill is an open-source subscription billing and payments platform built for scale, an alternative to Chargebee and similar billing SaaS. It handles complex subscription lifecycles, usage-based and recurring pricing, trials, add-ons, proration, invoicing, taxes, and dunning, and integrates with payment gateways through a plugin architecture. With a robust API, catalog-driven plan configuration, and an admin interface, it gives engineering and finance teams a programmable billing engine that can model intricate monetization without being locked into a vendor's pricing model.

StoresWiki LLC operates Kill Bill as a managed, privately hosted deployment. We provision a hardened, monitored instance, keep it and its plugins updated, and run regular backups of your billing data, so this revenue-critical system stays reliable. Self-hosting keeps your billing records and customer payment relationships on infrastructure you own, with no percentage-of-revenue fees and no per-seat charges.

It fits SaaS companies, platforms, and subscription businesses that need flexible, programmable billing at scale with full ownership of billing data and predictable, non-revenue-based cost.
