Top 10 Best SaaS Billing Tools in 202 6
1. Flexprice : Best Enterprise Grade Open Source Usage-Based Billing Infrastructure for AI and SaaS
Metering-first billing that runs inside your own cloud, not someone else’s.
Why It’s Great
Deploy it anywhere, same engine
Run Flexprice in your own VPC on AWS, Azure, or GCP, on-prem in any geography, or on Flexprice’s managed cloud — all three run the same engine.
Metering-first, built for usage-based and hybrid pricing
Real-time metering at high event volume across tokens, API calls, credits, and seats, settled as usage-based and hybrid pricing on one invoice.
Your usage and revenue data stay inside your infrastructure
Because Flexprice is open source and self-hostable, that data never has to reach a vendor’s cloud — meeting data residency, sovereignty, and audit requirements that hosted-only vendors can’t.
Enterprise-grade, and not tied to any payment gateway
Flexprice is the metering and billing layer itself, with parent-child accounts, RBAC, and ramped commitments — and it works with any payment gateway.
Overview
Flexprice is enterprise-grade, open source usage based billing infrastructure for AI and SaaS companies. It can be deployed in your own VPC, on-prem, or on Flexprice’s managed cloud.
