FOSSBilling
FOSSBilling is free, open-source billing and client-management software for hosting and other online service businesses. It can issue invoices automatically, send payment reminders, handle recurring or one-time pricing, support multiple currencies and apply promo codes. Hosting products can create and manage accounts through cPanel/WHM, DirectAdmin, HestiaCP, CWP and Plesk. Domain functions cover registration, renewal, transfers and WHOIS checks through registrar integrations, though domain prices are entered manually rather than retrieved live. A REST API provides admin, authenticated-client and public guest endpoints. Documented protections include HTTPS enforcement, session fingerprinting, CSRF protection, rate limiting, IP blocking, CAPTCHA and activity logs. It is self-hosted, requiring PHP 8.3, 8.4 or 8.5 and a MySQL-compatible database, with Apache, LiteSpeed/OpenLiteSpeed or NGINX. The project is beta, under active development, and notes rough edges and limited support.
