Best alternatives to UnitPay in 2026
When a company charges customers based on how much they actually use — a certain number of AI tokens, API calls, or generated images — regular invoicing software struggles, because it's built around flat monthly fees, not usage that changes every second. UnitPay is a billing system built specifically for that kind of pricing: it counts usage as it happens, turns it into a bill automatically, and tells the company in real time whether it's actually making money on each customer once server costs are subtracted. UnitPay meters usage events at scale (50M+ events/month claimed), handles multi-currency invoicing, and routes payments through existing processors like Stripe, Razorpay or Paddle rather than replacing them. It includes spend controls to prevent surprise bills for end customers, revenue-intelligence dashboards with churn prediction and margin/ROI tracking per customer, and a CPQ tool for negotiating custom enterprise quotes. It's SOC 2 Type II certified and GDPR-ready, and claims sub-10-minute setup with 1ms ingestion latency.
