## The Hook

FOSSBilling is a free billing and client management system for online service businesses: automated invoices and reminders, a client area, payment gateways and provisioning for hosting-style products.

## What's Good

Apache-2.0 (FOSSBilling/FOSSBilling), release 0.8.8 (2026-10-03), with commits landing daily. Popular with web hosting providers, but it also covers software licensing, digital downloads and subscriptions. Extension-friendly architecture for integrations. ★~1.7k.

## The Catch

The README says it is beta, with rough edges and limited support. It is PHP and aimed at the WHMCS-style hosting market, so it is not a general SaaS billing engine.

## Verdict

The free WHMCS alternative to try if you sell hosting or similar services.
