Enterprise Accelerator
Production-ready billing in weeks, not months.
Aviate is the proprietary enterprise layer built on Kill Bill's open-source core. It delivers production-grade infrastructure, pre-built integrations, and operational tooling so your team ships billing faster with zero vendor lock-in.
Why Aviate
Enterprise billing without the enterprise trade-offs
Aviate gives you the speed of a SaaS platform with the control of open-source infrastructure.
Weeks to Production
Skip 6+ months of infrastructure work. Aviate provides pre-configured cloud infrastructure with auto-scaling, monitoring, and battle-tested deployment templates.
Fixed, Predictable Pricing
Never pay a percentage of your revenue. Aviate uses fixed pricing that stays predictable as you scale, saving companies 60-80% compared to typical billing SaaS vendors.
Zero Vendor Lock-in
Built on 100% open-source Kill Bill core. Your data, your infrastructure, your code. Migrate away at any time with full data portability. No exit fees, no restrictions.
Enterprise-Grade Support
Access to the Kill Bill core engineering team. Support plans, architecture reviews, and migration assistance from the people who built the platform.
Production Monitoring
Pre-configured observability stack with real-time dashboards, alerting, and performance monitoring. Know exactly how your billing infrastructure is performing.
Cloud-Native Infrastructure
Deploy on AWS with auto-scaling, multi-AZ redundancy, and automated backups. Your billing infrastructure runs in your cloud account with full control.
Production-Ready Add-Ons
Everything you need to run a real billing operation
Kill Bill gives you the subscription billing engine. Aviate gives you everything else.
Dynamic Catalog Management
Define and version your product catalog entirely through APIs — no XML files, no redeployments. Create plans, pricing tiers, and usage-based billing meters on the fly. Every plan change is live immediately.
Metering & Usage Billing
Ingest usage events, aggregate them by configurable billing meters (SUM, COUNT, and more), and feed them directly into Kill Bill's invoicing pipeline. Purpose-built for AI token metering, API call counting, storage tracking, or any consumption-based model.
Wallet & Prepaid Credits
Give customers a credit wallet with automatic top-off. Aviate maintains a full double-entry ledger, auto-replenishes balances via configurable triggers, and applies credits at invoice time — all with distributed locking for safe multi-node operation.
Coupons & Discounts
Create coupons with percentage or fixed-amount discounts, plan-level filtering, and max-use enforcement. Aviate intercepts Kill Bill's entitlement and invoice pipelines to validate coupon eligibility and apply adjustments automatically.
Tax Computation
Configure tax codes per product with date-ranged rates, country-level resolution, and timezone-aware evaluation. Aviate injects tax line items into Kill Bill invoices with configurable decimal precision — no external tax provider required for straightforward tax regimes.
Custom Invoice Sequencing
Generate human-readable, sequential invoice numbers with configurable prefix, suffix, start value, and per-account or global scope. Replaces Kill Bill's default UUID-based invoice identifiers.
Aviate turns Kill Bill from a billing engine into an enterprise-ready billing platform — catalog management, metering, wallets, coupons, tax, and custom invoicing, all in a single plugin with a modern UI.
