Instead of Kill Bill
Kill Bill alternatives
Kill Bill combines subscription billing, configurable pricing models, invoices, and payment processing in an open-source platform with APIs and plugins. It supports usage-based billing, multiple currencies, proration, dunning, and tax automation. Kaui adds a web back office for price books, subscriptions, and payments, while deployment options include self-hosting and an AWS Marketplace setup. The AWS option costs about $40 per month plus AWS infrastructure; hosted-platform pricing follows a separate commercial model.

That breadth can suit businesses that need to shape billing around their own requirements, but self-hosted customers must run and upgrade the software. Community support comes with the open-source option, while paid support is separate. If your priority is payment acceptance, invoicing, or card controls rather than operating a programmable billing system, a focused service may be a better fit. Compare the billing controls you would give up with the payment methods, sales channels, integrations, and platform access each alternative provides.
