Enterprise billing infrastructure. Open source. Zero lock-in.

You need a billing system that won't become a bottleneck as complexity grows. Kill Bill gives you full control: deploy it in your infrastructure, customize the logic, and extend it without waiting on vendor roadmaps.

You need accurate revenue recognition, audit trails, and integrations with your existing financial stack. Kill Bill handles complex billing scenarios, including usage-based, prepaid, postpaid, multi-tenant, and white-label models. It maintains strong compliance and auditability.

You're scaling fast and vendor bills are scaling faster. Kill Bill offers predictable costs: no per-transaction fees, no revenue-based pricing. You own the infrastructure, you control the costs.

Scaling fast but cannot dedicate a full platform team? Aviate bridges the gap. It pairs the open-source Kill Bill core with a production-ready accelerator so you launch quickly. Fixed pricing (not a percentage of revenue) and far cheaper than commercial offerings. With Kill Bill and Aviate: you plan once, own the revenue stack, and avoid surprises later.
