Lago is an open-source metering and usage-based billing platform designed for B2B companies seeking transparency, flexibility, and control over complex billing workflows. Built as an alternative to proprietary solutions like Stripe Billing, Lago focuses on developer experience, composability, and supporting intricate pricing models.
Founded by a team with experience scaling the billing infrastructure at Qonto (a leading European fintech), Lago aims to address the challenges of building and maintaining in-house billing systems for SaaS and fintech businesses. The platform is self-hosted, modular, and community-driven, making it a popular choice among companies that value openness and the ability to customize their billing logic.
Lago serves organizations looking for a scalable way to handle metering, invoicing, and revenue recognition, especially those with usage-based or hybrid pricing strategies. Its open-source nature fosters a growing community and enables businesses to adapt the system to their specific needs without vendor lock-in.
