In their own words
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. A REST API lets users control the platform and automate workflows. 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. Its WHMCS importer can transfer currencies, users, admins, categories, products, tickets, orders, services, cancellations, invoices and payments. 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.
