Best Free Invoicing Software for Small Business (+ Fees)
The best free invoicing software for small business costs $0 a month. Compare Zoho Invoice, Wave, Square, Invoice Ninja and PayPal on real yearly fees.

The best free invoicing software for small business is Zoho Invoice if you send fewer than 500 invoices a year, and Wave if you also want free bookkeeping. Both cost $0 a month. What you really pay is the payment processing fee each time a client settles an invoice.

Best free invoicing software for small business is any billing tool that lets you create, send and track invoices with no subscription. The vendor earns its money elsewhere: card and bank fees, or paid upgrades. So the honest way to compare these tools is by total yearly cost, not by the sticker price.
Quick answer
Zoho Invoice has the strongest free feature set but caps you at 500 invoices a year. Wave pairs unlimited free invoicing with free accounting. Square and PayPal never cap invoices, but their card fees are the highest of the five, and over a year those fees cost far more than the software itself.
Key takeaways
- Sending invoices is free with every tool here. You pay about 1% to 3.5% only when a client actually pays.
- Zoho Invoice is free forever, with a limit of 500 invoices a year, 2 users and 3 projects.
- Wave's Starter plan keeps both invoicing and accounting free, with no invoice cap.
- On 120 card invoices of $500, yearly fees range from $1,776 to $2,152.80, depending on the processor.
- For large invoices, push clients toward bank payment. The ACH caps differ by 4x between providers.
What counts as free invoicing software for a small business?
Free invoicing software lets you create, send and track professional invoices with no monthly fee. It is free to use, but not free to get paid with. Each vendor takes a cut of card and bank payments, or sells paid upgrades for automation, branding and accounting.
The model is the same as a free website builder: the editor costs nothing, and the money is made on payments, storage and premium features. Invoicing works the same way, which is why our small business software hub compares tools on total cost, not on the headline price.
One more distinction matters. Some tools, like Zoho Invoice and Invoice Ninja, let you connect your own payment gateway, such as Stripe or PayPal. Others, like Wave and Square, process payments themselves at their own rates. That single difference decides most of what you will pay.

How do the top free invoicing tools compare on cost?
Zoho Invoice gives you the most features for free, but limits your volume. Wave, Square and PayPal have no invoice cap and make their margin on payment fees. The figures below come from each vendor's own pricing page as of October 2026.
| Tool | Monthly cost | Free-tier limit | Card fee | Bank (ACH) fee |
|---|---|---|---|---|
| Zoho Invoice | $0 forever | 500 invoices/yr, 2 users, 3 projects | Your gateway's rate (Stripe: 2.9% + $0.30) | Your gateway's rate (Stripe: 0.8%, cap $5) |
| Wave (Starter) | $0 | Unlimited invoices | 2.9% + $0.60 (Amex 3.4% + $0.60) | 1% (min $1) |
| Square Invoices (Free) | $0 | Unlimited invoices | 3.3% + $0.30 | 1% (min $1) |
| Invoice Ninja | $0 | Cloud: 5 clients; self-hosted: unlimited | Your gateway's rate | Your gateway's rate |
| PayPal Invoicing | $0 | Unlimited invoices | 2.99% + $0.49 (PayPal account: 3.49% + $0.49) | 1% (cap $10) |
Fees change often, so check each vendor's current page before you commit. Stripe's US standard rates are 2.9% + $0.30 for cards and 0.8% capped at $5 for ACH Direct Debit, according to Stripe's published pricing as of October 2026.
What do invoice payment fees cost over a full year?
On 120 card invoices of $500 each, $60,000 billed in a year, the processing fees range from $1,776 to $2,152.80. The software is free in every case. The roughly $377 gap comes entirely from the payment processor.
| Processor | Fee per $500 card invoice | Yearly fees on 120 invoices |
|---|---|---|
| Stripe (via Zoho Invoice or Invoice Ninja) | $14.80 | $1,776.00 |
| Wave | $15.10 | $1,812.00 |
| PayPal (card) | $15.44 | $1,852.80 |
| Square (Free plan) | $16.80 | $2,016.00 |
| PayPal (client pays with PayPal account) | $17.94 | $2,152.80 |
These are illustrative calculations from the published rates, not quotes. Your real numbers depend on the card mix, any international cards, and the invoice size.
The software is never the expensive part. Your payment processor is.
Why bank payments win on large invoices
ACH caps matter much more than card rates once invoices pass about $1,000. On a $2,000 invoice paid by bank, Wave and Square's Free plan each charge $20, PayPal charges $10 thanks to its cap, and Stripe charges $5.
Over 12 such invoices a year, that is $240 against $60 for the exact same money moving. If you bill retainers or project fees, choose a tool whose bank option has a low cap, then make it the default payment method on your invoices.
Which free invoicing tool fits which business?
Each of the five tools wins in a different situation. Pricing and limits below were checked on vendor sites in October 2026, and every evaluation draws on vendor documentation and public reviews.
Zoho Invoice: the best free tier overall
Zoho Invoice is free forever, with recurring billing, time tracking, expense tracking and a client portal included. Those features usually belong to paid plans elsewhere.
The limit is volume. According to Zoho's pricing page, the free plan allows 500 invoices a year, two users and three projects, and shows a "Powered by Zoho Invoice" mark. Accounts inactive for more than 180 days can have their data deleted, so log in regularly or export backups.
To get paid, you connect a gateway such as Stripe or PayPal and pay that provider's standard rate. Pair it with the free apps in our team productivity stack and a solo operator can run the back office for $0 a month.
Wave: the best free invoicing plus accounting
Wave's free Starter plan includes unlimited invoices, estimates, bills and bookkeeping records. For US and Canadian freelancers, that bundle works as free accounting software and a billing tool in one place.
Card payments cost 2.9% + $0.60, Amex 3.4% + $0.60, and bank payments 1% with a $1 minimum. According to Wave's pricing page, the Pro plan costs $19 a month or $190 a year and removes the $0.60 fixed fee on only your first 10 card transactions each month.
That saves you at most $6 a month, so Pro only pays for itself if you need its bank sync, late-payment reminders or branding.

Square Invoices: the best fit if you already use Square
Square Invoices has no monthly fee and no invoice cap. On the Free plan, invoice card payments cost 3.3% + $0.30 and ACH costs 1% with a $1 minimum. Square's paid Plus plan caps ACH at $10 and lowers card fees.
It shines if you already run a Square point of sale, since invoices, payments and stock tracking share one dashboard. For shops, Square doubles as basic inventory management software small business owners can grow into before buying a dedicated system. The trade-off: you have to use Square as your processor.
Invoice Ninja: the best for developers and self-hosting
Invoice Ninja is a source-available invoicing app. According to Invoice Ninja's January 2026 pricing update, the free cloud plan covers up to 5 clients with unlimited invoices, and Pro costs $14 a month.
The smart move is self-hosting. Install it on a cheap virtual server and you get unlimited clients and invoices for the cost of hosting. An optional $40-a-year white-label license removes the branding from client-facing pages and PDFs.
PayPal Invoicing: the best for client trust
PayPal Invoicing costs nothing to send, and most clients recognize the checkout right away. Card payments cost 2.99% + $0.49, while payments made through a PayPal account cost 3.49% + $0.49, the highest rate on this list.
It works well for international clients and one-off jobs, though cross-border payments add an extra fee. At volume, encourage Pay by Bank, which costs 1% capped at $10 per transaction, half the bank fee Wave or Square's Free plan charge on a $2,000 invoice.
How do you choose free invoicing software in four steps?
Choose based on two numbers: how many invoices you send a year, and how your clients pay. Features come second, because every tool here covers the basics of invoicing.
- Count your invoices. Under 500 a year and you want the most features: Zoho Invoice.
- Check whether you need books. If you want double-entry accounting at no cost: Wave Starter.
- Look at your current setup. Already on a Square point of sale: Square Invoices.
- Weigh technical comfort. Comfortable running a server and obsessed with costs: Invoice Ninja self-hosted.
Next, estimate a year of fees with your own average invoice, using the yearly fee table as a template. A free tool with a cheap processor almost always beats a free tool with an expensive one.
Keep clean records whatever tool you use. The IRS recordkeeping guidance (as of October 2026) expects businesses to keep supporting documents such as invoices and proof of payment, so export backups even from a free plan.

What other free tools pair well with invoicing software?
Invoicing rarely works alone. Most small operators add a few free basics around it to keep the back office running without monthly bills.
- A free CRM to track leads and clients before they ever receive an invoice.
- A free password manager so shared logins for billing and payment gateways stay secure.
- Basic HR software once you add a contractor or two and need clean pay records.
- Gantt chart software to map the project milestones you bill against.
Securing those logins matters more than most owners expect. Back your billing stack with solid security software for small business so a leaked password never exposes client payment data.
Clear processes also make it easier to hand billing off to someone else. The same habit of specific, written feedback helps upward too, as our guide to nice things to say about your boss in a review shows.
How do invoicing, business credit and supply costs connect?
Free invoicing brings money in, but growth usually needs credit going out. Many owners open a secured business credit card early to start building a business credit score before they apply for higher limits.
If you buy supplies in bulk, checking Costco Business Center locations can be worth it. Costco Business Centers stock office, food service and janitorial goods in larger pack sizes, and a Costco membership business tier pairs well with a rewards card for tracked spending.
Costco business centers locations are far fewer than regular warehouses, so check the nearest one before you plan your purchasing around it.
