Invoice Ninja
💸 Finance & AccountingOpen-source invoicing and payments. Self-host or use their cloud. Free for up to 20 clients. The no-cost invoicing tool.
Our Take
Invoice Ninja is the open-source invoicing tool that quietly does everything FreshBooks and QuickBooks charge hundreds for — and does it well. Self-host it for free or use their cloud version for pocket change. It handles invoices, proposals, expenses, time tracking, and even basic project management. The UI won't win design awards, but the functionality-to-cost ratio is unbeatable for small teams.
What we like
- Genuinely free and open-source — self-host on your own server with zero ongoing costs
- Covers invoicing, proposals, expenses, recurring billing, and basic project management in one tool
- Supports 15+ payment gateways including Stripe, PayPal, and bank transfers
- White-labelling and custom branding included even on the free tier
Where it falls short
- UI feels functional rather than polished — FreshBooks and Xero look noticeably better
- Self-hosting requires technical knowledge to set up and maintain securely
- Reporting is basic compared to proper accounting software — you'll still need Xero or QuickBooks for tax time
Verdict
Invoice Ninja is the best free invoicing solution available, full stop. If you're a freelancer or small team that needs professional invoices without paying FreshBooks prices, start here. But it's invoicing, not accounting — you'll want Xero or QuickBooks alongside it for proper bookkeeping.
