Open-Source Usage Metering and Billing Engine for SaaS Companies
Usage-based billing is becoming standard for SaaS but building metering infrastructure is complex. An open-source usage metering engine with billing integration would let SaaS companies implement consumption pricing without months of engineering.
Problem Statement
SaaS companies wanting usage-based pricing must build custom metering: event collection, real-time aggregation, entitlement enforcement, and billing system integration. This takes months of engineering and introduces billing accuracy risks.
The Idea
An open-source usage metering and billing engine that handles event ingestion, aggregation, pricing calculation, and billing system integration for SaaS companies adopting usage-based pricing.
Why Now
Usage-based pricing is the fast-growing billing model in SaaS. OpenMeter emerged as open-source metering in 2024-2025. The complexity of building accurate, real-time metering deters many SaaS companies from adopting consumption pricing.
Target User
SaaS engineers, billing teams, and product managers implementing usage-based pricing
Target Market
SaaS companies adopting or considering usage-based pricing models (thousands of companies)
