SolidInvoice

The open-source invoicing platform for freelancers and small businesses.

Send beautiful quotes and invoices, accept online payments, automate recurring billing — and own every byte of your data.

Why SolidInvoice?

Most invoicing tools force a trade-off: easy to use or respectful of your data. SolidInvoice gives you both. It's a mature, production-ready billing platform you can run on your own server for free, or let us host it: start on the Free plan, with paid plans from $9/month — no lock-in. Built on Symfony 8.1 and PHP 8.4, it's designed to be extended, integrated, and trusted.
