About SolidInvoice

SolidInvoice is an open source invoicing and billing tool that you install on your own server. It handles creating professional invoices, quotes, and recurring billing cycles. Built with PHP and MySQL, it gives you full control over your financial data without relying on third party services.

SolidInvoice supports multiple tax rates, customizable invoice templates, and integrates with payment gateways like Stripe, PayPal, and Authorize.net. A client portal lets customers view and pay invoices online. The dashboard provides reports on income, outstanding balances, and overdue payments. The software is released under the MIT license.

This tool is ideal for freelancers, small businesses, and agencies that want a self-hosted billing solution. The active community provides regular updates and security patches. Documentation is available on the official site along with a demo for testing.
