Frequently Asked Questions

? Is SolidInvoice hard to install?

SolidInvoice is easy to install via Docker (using provided compose files) for users with basic server knowledge. Traditional setup requires PHP 8.1+, MySQL/MariaDB, and web server (Apache/Nginx)—documentation guides through both methods.

? Is it a good alternative to FreshBooks?

Yes—SolidInvoice offers core invoicing, billing, and client management features like FreshBooks but as an open-source self-hosted option. It avoids subscription costs and gives full data control, though FreshBooks has more advanced integrations and a simpler UI for new users.

? Is it completely free?

SolidInvoice is 100% free and open-source (MIT license). There are no paid tiers, hidden fees, or usage limits—you can use all features and modify the code to fit your needs without any cost.
