Lago
Meter usage and calculate subscription or consumption-based customer bills.
What it helps with
Lago is billing infrastructure for software companies, not a general invoice screen for a local business. A SaaS team can send usage events, define pricing plans, calculate charges, manage subscriptions, and connect payment or accounting workflows through APIs. An agency could implement it for a client with complex usage-based pricing. It becomes financially critical infrastructure, so event accuracy, idempotency, taxes, credit notes, payment-provider behavior, and reconciliation need engineering and finance ownership. The hosted and self-hosted editions should be compared explicitly.
Best fit
Best for SaaS product and finance engineering teams; not for a non-technical freelancer who only needs simple invoices.
Setup reality
Ops-heavy; API, worker, database, Redis and related services must be configured and monitored; integrations and billing tests require developers.
License context
Copyleft licenseBusiness use is allowed. Sharing duties depend on the specific license and how modified software is distributed or offered.AGPL-3.0 for the open-source core; modified network service deployments may require offering source; enterprise/cloud features can differ.
