Lago

Lago is an open-source billing platform that connects product usage and commercial terms with customer invoices. It supports usage-based, subscription, prepaid, and hybrid pricing, plus quotes, order forms, prepaid credits, entitlements, quotas, subscription and usage charges, and itemized invoices. For AI products, Lago can meter input, output, and cached tokens separately and assign usage to customers for billing. Applications can connect through a REST API, official JavaScript, Python, Ruby, and Go SDKs, or signed webhooks. Listed AI integrations include OpenAI, Anthropic, AWS Bedrock, Google Gemini, and Mistral; payment and finance integrations include Adyen, Stripe, NetSuite, and Xero. The Open source plan is free, licensed under AGPLv3 and self-hosted. Lago Premium is available as cloud or self-hosted deployment, including on-premises or in a VPC, but pricing is provided after contacting Lago. Lago states it is SOC 2 Type II certified and describes single sign-on, role-based access controls, and audit logs. Premium includes platform support, business-hours incident management, and implementation guidance.
