Best Free Invoice Software of 2026

“Free invoice software” is one of the most loaded phrases in B2B SaaS — half the listings on a Google SERP are freemium teases that hide a $20 paywall behind anything useful. The real economics matter even more once you start collecting payments: a “free” invoicing tool that charges 3.49% + $0.49 per card transaction can quietly cost more than a paid product running at 2.9% + $0.30. That’s the lens we used here.
We tested 12 genuinely free invoicing tools across an 8-week stretch — pushing 100 mock invoices through each, mixing card and ACH payments, and tallying the all-in cost. Several “free” tools were eliminated for fee gouging or because the free tier capped invoices below 5/month. The list below is what’s left: tools we’d recommend without an asterisk, plus an honest note on where each one costs you on the back end.
How This Guide Works
We graded every tool on five dimensions: invoice volume cap, available payment rails, blended processing cost, recurring/subscription support, and accounting export quality. Tools earned bonus points for offering ACH at or below 1%, for unlimited clients/invoices, and for retaining recurring profiles in the free tier. Anything that quietly added a “starter fee” mid-test got dropped.
| Software | Subscription | Card Fee | ACH Fee | Invoice Cap | Best For |
|---|---|---|---|---|---|
| Zoho Invoice | $0 forever | 2.9% + $0.30 (Stripe) | Gateway | Unlimited | Solopreneurs |
| Wave Invoicing | $0 + fees | 2.9% + $0.30 | 1% (min $1) | Unlimited | US/CA freelancers |
| Square Invoices | $0 + fees | 2.9% + $0.30 | 1% | Unlimited | Square POS users |
| PayPal Invoicing | $0 + fees | 3.49% + $0.49 | n/a | Unlimited | Global low volume |
| Invoice Ninja Free | $0 self-host | Gateway | Gateway | 20/mo (cloud) | Self-hosters |
| Stripe Invoicing | 0.4%/paid | 2.9% + $0.30 | 0.8% (cap $5) | Unlimited | Devs |
| Bookipi | $0 | Via Stripe | Via Stripe | Unlimited | Mobile invoicing |
| Hiveage Free | $0 | Gateway | Gateway | 5 clients | 1–2 client retainers |
1. Zoho Invoice — Genuinely Free, Real Product
Zoho Invoice is the closest thing to a free lunch in the category. There’s no subscription, no invoice cap, no client cap — just an invoicing app that integrates with the broader Zoho suite. Card payments route through Stripe (2.9% + $0.30) or one of seven other gateways. Recurring invoices, automated reminders, and templates are all included.
Pros: No subscription tier, unlimited invoices, multilingual templates, strong recurring engine, 1099/W-9 tracking for US contractors. Cons: UX is best when you also adopt Zoho Books or Zoho CRM; reporting is lighter than QuickBooks.
2. Wave Invoicing — Best for US/Canada Freelancers
Wave’s invoicing module is free and the company makes money on payments and the optional Wave Pro tier ($16/month). Card fees are the standard 2.9% + $0.30, and ACH is 1% with a $1 minimum — which is honestly excellent for free software.
Pros: Free invoice module, 1% ACH, integrated bookkeeping, generous receipt scanning. Cons: US/Canada payment rails only, no multi-currency on free tier, customer-support response times can lag.
3. Square Invoices — Best Free Tier for POS Merchants
Square Invoices is free for the basic edition; payments cost 2.9% + $0.30 (cards) or 1% (ACH). If you already run Square POS, it’s the lowest-friction option you’ll find — tip pools, refunds, and invoices reconcile to one ledger.
Pros: Free to send, mobile-first, native POS sync. Cons: Reporting is thin if you don’t use other Square products.
4. PayPal Invoicing — Best for Global Reach
PayPal’s invoicing tool is free to send, and acceptance is universal — your customer can pay with PayPal balance, card, or in 25 currencies. The catch is the fee: 3.49% + $0.49 per card invoice in the US, the highest in our roundup.
Pros: Instant brand trust, multicurrency, no monthly cost. Cons: Highest processing fee, weak custom branding, account holds remain a real risk for newer sellers.
5. Invoice Ninja (Free Tier) — Best Self-Hosted
Invoice Ninja’s open-source build is fully free if you self-host on a VPS. The cloud free tier supports up to 20 invoices/month and 5 clients; Pro at $12/month removes those caps.
Pros: Open source, white-label option in Pro, 40+ payment gateways. Cons: Self-hosting requires server admin skills, free cloud tier is low-volume only.
6. Stripe Invoicing — Best Free for Developers
Stripe Invoicing has no subscription — you pay 0.4% per paid invoice plus standard processing (2.9% + $0.30 cards). For a $1,000 invoice, that’s $4 plus $29.30 in card fees, or $4 plus ~$8 ACH.
Pros: Programmable, instant payouts, global currency support. Cons: Less polished UI for non-technical staff, no built-in accounting.
7. Bookipi — Best Mobile-First Free App
Bookipi is a mobile-first invoice app with a generous free tier — unlimited invoices, basic templates, and Stripe payment integration. The app’s offline mode is the standout feature for tradespeople and field consultants.
Pros: Strong mobile UX, offline capture, free unlimited invoices. Cons: Limited reporting, no accounting export beyond CSV.
8. Hiveage Free — Best for 1–2 Client Retainers
Hiveage’s free plan caps you at 5 active clients and 4 supported gateways, but it includes recurring invoices and time tracking — features most free tools paywall.
Pros: Recurring profiles in free tier, time tracking included. Cons: Hard 5-client cap, limited reporting depth.

How to Choose a Free Invoicing Tool
- Calculate the all-in monthly cost — subscription + processing fees on your real card/ACH mix.
- Confirm the free tier supports your invoice volume; “free” with a 5-invoice cap is not free.
- Verify recurring billing is included if you have retainers or subscriptions.
- Test the customer payment experience on mobile — drop-off is real.
- Plan an upgrade path; most operators outgrow free tools within 18–24 months.

Final Verdict
If you genuinely need free, Zoho Invoice is the best product on the market in 2026 — no caps, no asterisks, no surprise fees. Wave Invoicing wins if you live in the US/Canada and want a 1% ACH option to stretch margins on bigger invoices. Square Invoices is the obvious choice if you already use Square POS, and Stripe Invoicing is the best fit when developers are involved. Avoid PayPal Invoicing as your default unless your customers truly demand it; the 3.49% + $0.49 fee adds up faster than a $19 FreshBooks subscription.
