Which do you use?
Who Should Choose What?
→ Choose Zoho Invoice if:
You want the most polished free invoicing experience and already use (or plan to use) other Zoho tools. Best for freelancers with fewer than 5 clients and small businesses wanting a clean, professional invoicing solution.
→ Choose Invoice Ninja if:
You want open-source software, need more than 5 clients on a free plan, or want to self-host for full control. Best for tech-savvy freelancers, privacy-conscious users, and businesses needing proposals alongside invoicing.
→ Consider neither if:
For full accounting (not just invoicing), check Wave (free) or FreshBooks ($17/mo). For enterprise invoicing, QuickBooks Online is the standard. For the simplest possible invoicing, PayPal invoicing is built into your account.

Frequently Asked Questions
Editor's Take
For most freelancers just starting out, Zoho Invoice is the path of least resistance — sign up, create a professional invoice in 5 minutes, get paid. But once I hit the 5-customer limit, I switched to Invoice Ninja self-hosted and never looked back. The freedom of open source plus unlimited clients for $0/month is hard to argue with if you are comfortable with basic server setup.
