"UnitPay let us launch usage-based pricing without an engineering sprint. We changed models three times in our first month — no deploys needed."
"Real-time margin visibility changed everything. We found a $50K monthly leak in week one that our spreadsheets never caught."
"Our billing used to take 3 engineers. Now it takes zero. UnitPay handles metering, pricing, invoicing — everything."
"The only billing platform that actually understands AI-native pricing. Token metering, credit packs, hybrid models — all out of the box."

Connected to
everything.
UnitPay plugs into your existing stack — payments, CRM, accounting, data, and more.
Questions we get asked.
We ingest events via a high-throughput REST API with sub-12ms p99 latency. Events are automatically deduplicated, so you can fire and forget from your AI agents. No batching or queuing logic needed on your side.
Yes. UnitPay connects to your existing Stripe account. You keep your payment relationships and customer data. We add usage metering, flexible pricing, and revenue intelligence on top.
All of them. Per-token, per-seat, per-API-call, tiered, volume, flat-rate, prepaid credits, or any hybrid. Mix multiple pricing models in a single plan, all from the dashboard with no code changes required.
Free until $500K ARR. No credit card required to start. Full platform access, including usage metering, pricing, invoicing, and revenue intelligence, at zero cost until you reach meaningful revenue.
Yes. We have a guided migration flow. Most teams migrate their existing subscriptions in under 2 hours. UnitPay sits alongside Stripe for payments while adding the metering and intelligence layer Stripe Billing lacks.
Most teams are live in under 10 minutes. Install the SDK, point it at your event source, and start billing. TypeScript, Python, and REST API all supported.
