In their own words
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.
Paymenter
Paymenter is an open-source billing platform tailored to hosting companies. It supports automated billing and service deployment, with custom themes and extensions available through its marketplace.

Built-in payment gateway extensions include Mollie, PayPal and Stripe; server extensions include cPanel, Convoy, DirectAdmin, Enhance, Plesk, Pterodactyl, VirtFusion and Virtualizor. Proxmox is available only as a paid extension. The platform includes customer support tickets and can receive ticket replies through email piping.

Paymenter is released under the MIT License and is available as a self-hosted product or hosted PaaS. Self-hosted installation lists Ubuntu 24.04 and 22.04, CentOS 9 and 8, and Debian 13, 12 and 11 as supported; Windows is unsupported. The Paymenter plan costs nothing. PaaS costs €5 a month, with free daily backups and Cloudflare DDoS protection described for hosted instances. The installation guide warns that losing the APP_KEY makes encrypted data irrecoverable.
