Kill Bill is an open-source subscription billing and payments platform that manages subscriptions, invoicing, payment processing, and dunning through a REST API and extensible plugin architecture. It is self-hosted (or cloud-deployed) Java software designed to replace SaaS billing vendors without vendor lock-in.
Use cases
- run recurring subscription billing for a SaaS product
- generate invoices and process payments through gateways like Stripe
- handle trials, coupons, proration, and plan upgrades/downgrades
- self-host billing infrastructure to avoid vendor lock-in and revenue-share fees
- integrate billing with ERP/CRM systems like NetSuite or Salesforce
- implement usage-based and one-time billing models
- manage dunning and payment retries for failed charges
When to avoid
- you want a turnkey hosted SaaS billing solution with zero operations
- you only need simple one-off invoicing without subscriptions
- your team cannot operate JVM-based infrastructure and databases
