Our verdict on FOSSBilling

FOSSBilling is a free, open-source billing and client management platform aimed at hosting providers and digital service businesses. It combines recurring and one-time pricing with invoice generation, payment reminders, domain management, and client support ticketing. Because it is self-hosted, it is suited to teams that want to run their billing software themselves and connect it to their hosting operations, rather than rely on a hosted billing service.

Its hosting focus shows in the supported integrations: cPanel/WHM, Plesk, DirectAdmin, HestiaCP, and CWP can be used for hosting account provisioning. Domain workflows include registration, renewal, transfer, and management, with Namecheap and Netim among the listed registrar integrations. PayPal and Stripe are supported payment gateways. Multi-currency billing includes exchange-rate synchronization, while invoice PDFs can be generated and customized. Themes, modules, payment gateways, and server managers are extensible, and a REST API provides admin, client, and guest endpoints. These capabilities make FOSSBilling a practical fit when billing is closely tied to hosting and domain services.

The core project is free and open source, rather than divided into paid tiers. Its narrower focus is an important trade-off for subscription businesses: usage-based pricing is not supported, and usage-based pricing is described as planned. Businesses that depend on metered charges or need deeper subscription controls should compare it with a dedicated subscription billing product. FOSSBilling is the more suitable choice for hosting providers seeking self-hosted invoicing, recurring charges, provisioning, and domain workflows in one system; it is less suited to businesses whose billing depends on consumption measurement or advanced subscription management.
