[!NOTE] FOSSBilling is under active development and currently considered beta. Expect rough edges and limited support.

FOSSBilling is a free, open-source billing and client management system. It helps online service businesses automate invoicing, payments, and client communication. While it’s popular with web hosting providers, it also works well for software licensing, digital downloads, and subscription services.

Features

• Billing & Invoicing: automated invoices, reminders, and basic reporting.
• Client Management: a central place for client data and communication.
• Extensibility: extension-friendly architecture for integrations and custom features.
• Payments: support for multiple gateways.
• Translations: community-powered, multi-language interface.
• Responsive UI: usable on desktop and mobile.
• Security-focused: built with security best practices in mind.
