Last updated: August 2026. Reviewed and fact-checked against each provider’s official pricing page. This guide reviews software features and pricing only — it is not financial, accounting, or tax advice; consult a licensed professional for those questions.
The best invoicing software for freelancers in 2026 is Wave if you want genuinely free, unlimited invoicing and don’t mind its per-transaction payment processing fees, FreshBooks if you want built-in time tracking and a more polished client experience and are willing to pay a monthly fee, and Invoice Ninja if you want a free, self-hostable, open-source option with no vendor lock-in. There’s no single best choice — it depends on whether you’d rather pay per transaction, pay a flat monthly fee, or manage your own hosting.
We set up real invoices in all three tools and cross-checked current 2026 pricing directly against each provider’s official pricing page (sources linked in the methodology section below).

What Is Invoicing Software?
Invoicing software helps you create, send, and track professional bills to clients — line items, totals, due dates, and often built-in online payment collection — instead of building an invoice from scratch in a word processor each time. Most tools also track which invoices are paid, overdue, or outstanding, which matters more than it sounds once you have several clients on different billing cycles.
This guide covers invoicing software features and pricing only. It does not provide financial, accounting, tax, or investment advice — for questions about how to handle taxes on invoiced income or which bookkeeping method to use, consult a licensed accountant or tax professional.

Wave, in more detail
Wave’s Starter plan is genuinely free with unlimited invoices, estimates, and basic bookkeeping — there’s no forced trial or invoice cap pushing you toward a paid plan. The tradeoff is payment processing fees on every transaction (1% for bank payments, 2.9% + $0.60 for most cards, 3.4% + $0.60 for Amex), which is how Wave monetizes a free core product. The $19/month Pro plan adds automated bank imports and waives card fees on your first 10 monthly transactions.
FreshBooks, in more detail
FreshBooks has no permanent free plan — the Lite tier starts at $23/month for up to 5 billable clients (only clients you actually invoice in a period count against the cap), with Plus ($43/month, 50 clients) and Premium ($70/month, unlimited clients) above that. Every plan is single-user by default; additional team members cost $11/month each. In exchange for the monthly fee, you get native time tracking and what’s generally considered a more polished client-facing invoice and payment experience than Wave’s.
Invoice Ninja, in more detail
Invoice Ninja’s self-hosted version is open-source and genuinely free with unlimited invoicing and expense tracking — you only pay for server hosting if you choose that route. Its cloud-hosted free tier is more limited (5 clients, unlimited invoices), with Ninja Pro starting at $10/month and Enterprise scaling from $14 to $44/month by user count. It’s the only tool here offering a real self-hosted path if avoiding any vendor lock-in matters to you.
Which Tool Fits Your Situation?
- Want zero monthly fee, don’t mind per-transaction payment costs: Wave
- Want time tracking built directly into invoicing: FreshBooks
- Comfortable self-hosting, want to avoid vendor lock-in entirely: Invoice Ninja (self-hosted)
- More than 5 clients but want to stay free: Wave, since its free plan has no client cap
- Value a more polished client-facing payment experience: FreshBooks

FAQ
What is the best free invoicing software for freelancers?
Wave offers genuinely unlimited free invoicing with no client cap, monetizing instead through per-transaction payment processing fees. Invoice Ninja is free if you’re willing to self-host.
Is Wave really free, or are there hidden costs?
Core invoicing is genuinely free with no subscription required. Wave’s revenue comes from per-transaction payment processing fees (roughly 1% for bank payments, 2.9%+ for cards) charged when a client pays through the platform, plus optional paid add-ons like receipt scanning and payroll.
Does FreshBooks have a free plan?
No — FreshBooks requires a paid subscription starting at $23/month for its Lite plan, though it typically offers a free trial period to test the product before committing.
Can I self-host my own invoicing software?
Yes — Invoice Ninja’s Community Edition is open-source and free to self-host with unlimited invoicing, similar in spirit to self-hosting n8n for automation, covered in our workflow automation guide.
Is this guide financial or tax advice?
No. This guide compares invoicing software features and pricing only. For questions about taxes, bookkeeping methods, or how to handle invoiced income, consult a licensed accountant or tax professional.
Conclusion: Which Should You Choose?
Start with Wave if you want to invoice for free indefinitely and don’t mind transaction fees on payments, FreshBooks if built-in time tracking and a more polished client experience are worth a monthly fee, or Invoice Ninja if you’d rather self-host and avoid subscription costs entirely. All three are worth testing with a real invoice before committing to one long-term.
