The best free invoice software for most small businesses in 2026 is the IncomeChecker.com Invoice Generator when you need a clean PDF invoice in two minutes with no account, and Wave when you want free invoicing tied to bookkeeping. We compared seven invoicing apps on what you pay, what customers pay to settle an invoice, client limits, and how long it takes to send a first invoice.

Key Takeaways

  • Truly free invoicing exists. The IncomeChecker.com generator, Wave Starter, PayPal, and Square Invoices Free all let you create invoices for $0, so the real cost is the processing fee when a customer pays by card.
  • Processing fees matter more than subscription prices for most freelancers. On a $1,000 invoice paid by card, fees range from about $29.30 (FreshBooks, Square Plus) to $35.39 (PayPal checkout via PayPal or Venmo balance).
  • Client caps are the hidden limit on "free" plans. Invoice Ninja Free and Zoho Invoice Free both cap you at five clients, and FreshBooks Lite caps billable clients at five on a paid plan.
  • If you invoice a few times a month, a no-account generator is faster than any app. You fill in line items, tax, and a due date, then save a PDF and email it yourself.
  • If you invoice weekly and want reminders, recurring invoices, and books in one place, Wave and FreshBooks are the strongest picks, and Invoice Ninja wins if you want open-source software you can self-host.

The IncomeChecker.com Invoice Generator builds a clean invoice with line items, tax, discounts, and a due date.

What Free Invoice Software Actually Is (and What It Is Not)

Invoice software creates a formal request for payment: your business details, the customer, an invoice number, the issue and due dates, itemized charges with quantities and rates, tax, discounts, the total due, and how to pay. Good invoicing software keeps that format consistent so customers can pay quickly and your records stay clean at tax time.

There are three kinds of tools in this category. Invoice generators produce a single invoice as a PDF, usually with no account and nothing stored. Invoicing apps store customers and invoices, send them by email or link, collect card or bank payments, and chase late payers with reminders. Accounting suites such as Wave and FreshBooks wrap invoicing into bookkeeping, expenses, and reports.

Free invoice software is not the same as free payments. Almost every app that lets customers pay online charges a processing fee on each payment, typically 2.9% to 3.5% plus a fixed fee for cards and around 1% for bank transfers. A "free" app can cost more than a paid one if most of your customers pay by card.

Invoice software is also not a substitute for accounting or tax advice. An invoice records what you billed; it does not record that you were paid, and it does not file sales tax for you. If you need a proof of payment after the money arrives, send a receipt. If you need to quote a price before the work starts, send an estimate or a quote instead of an invoice.

How We Ranked These Free Invoicing Tools

We ranked each tool on objective, published facts from its own pricing and product pages, checked in October 2026. Every tool was scored on the same five criteria:

  1. Cost to send invoices. The monthly price of the cheapest plan that lets you create and send invoices, and whether a $0 plan exists.
  2. Card and bank processing fees. The published percentage and fixed fee your customer’s card or bank payment costs you, and what a $1,000 card payment nets.
  3. Client and invoice limits. How many clients or invoices the free or entry plan allows before you must upgrade.
  4. Time to first invoice. Whether you can produce a finished invoice without creating an account, connecting a bank, or verifying identity.
  5. Ongoing features. Recurring invoices, automatic reminders, estimates, and bookkeeping for businesses that invoice every week.

The Best Free Invoice Software in 2026

These are the seven best free and low-cost invoicing tools for small businesses, freelancers, contractors, and landlords. We ranked them for the common case: a small business that sends a handful of invoices a month and wants to pay as little as possible. If you invoice dozens of clients a week, read the "Best suited for" note on each tool, because the right pick changes with volume.

1. IncomeChecker.com Invoice Generator, best for fast one-off invoices with no account

Free, no sign-up

The IncomeChecker.com Invoice Generator is the fastest way to produce a professional invoice when you do not want another software subscription. Open the page, add your business and customer details, enter line items with quantities and rates, and set a tax rate, discount, and due date. The total recalculates as you type. When it looks right, save it as a PDF from your browser’s print dialog and email it yourself.

Nothing is stored on a server. The invoice is built in your browser, so there is no account to create, no client limit, and no watermark on the finished document. Because the generator does not process payments, there is no processing fee either: you include your preferred payment instructions, such as a bank transfer, Zelle, or a check, and keep 100% of the invoice total.

The tradeoff is that it is a generator, not a billing system. It does not send automatic reminders, schedule recurring invoices, or track who has paid. For freelancers, contractors, and landlords who send a few invoices a month, that is usually a feature rather than a gap. The same site includes free estimate, quote, receipt, and credit note generators, so the documents before and after the invoice match.

Key numbers

  • Price: $0, with no account, no watermark, and no invoice limit
  • Processing fees: none, because you choose how customers pay you
  • Time to first invoice: about 2 minutes
  • Saves to PDF through your browser’s print dialog
  • Includes line items, tax rate, discount, notes, and due date
  • Sister tools: estimate, quote, receipt, proforma, credit note, purchase order, and packing slip generators

Best suited for

Freelancers, contractors, and landlords who send fewer than ten invoices a month and want a clean PDF without signing up. It also suits anyone who needs a single invoice today and does not want to compare apps.

2. Wave, best for free invoicing with built-in bookkeeping

Starter $0; Pro $19/month or $190/year

Wave is the best free option if you want invoicing and bookkeeping in the same place. The Starter plan costs nothing and includes unlimited invoices, estimates, and bills, plus a mobile app for invoicing on the go. Payments recorded against invoices flow into Wave’s bookkeeping, which saves time at tax season compared with a standalone generator.

The catch is the card processing fee. On Starter, Wave charges 2.9% plus $0.60 per card transaction, and 3.4% plus $0.60 for American Express. The $0.60 fixed fee is double what Stripe-based tools typically charge, so on many small invoices it adds up. Wave Pro, at $19 a month or $190 a year, removes the fixed fee on the first ten card transactions each month and adds automation features.

Wave says customers who enable online payments get paid three times faster than those paid by cash or check. That claim matches the general pattern across every app here: a "Pay now" button shortens the time to payment more than any template change.

Key numbers

  • Starter plan: $0 with unlimited estimates, invoices, and bills
  • Pro plan: $19/month, or $190/year billed annually, per business
  • Card fees on Starter: 2.9% + $0.60 per transaction (3.4% + $0.60 for Amex)
  • Card fees on Pro: 2.9% + $0 on the first 10 transactions each month, then Starter rates
  • A $1,000 card payment nets about $970.40 on Starter
  • Available to businesses in the US and Canada

Best suited for

US and Canadian sole proprietors who want free invoicing and free basic bookkeeping in one account. It is less ideal if most customers pay small invoices by card, because the $0.60 fixed fee on Starter adds up.

3. Invoice Ninja, best for open-source invoicing you can self-host

Free up to 5 clients; Pro $14/month or $140/year

Invoice Ninja is the best pick for businesses that want full control over their invoicing software. Its code is published on GitHub, and the company runs a separate self-hosting site, so a technical owner can run Invoice Ninja on their own server instead of using the hosted version.

The hosted Free plan includes unlimited invoices but caps you at five clients. Ninja Pro removes the client limit for $14 a month or $140 a year, which works out to about $11.67 a month, and is one of the lowest paid prices in this list. Enterprise pricing scales by the number of account users, starting at $18 a month for one or two users.

Because Invoice Ninja connects to outside payment gateways rather than running its own processor, your card fees are whatever your chosen gateway charges. That flexibility is useful if you already have a merchant account with a negotiated rate.

Key numbers

  • Free plan: $0 with unlimited invoices for up to 5 clients
  • Ninja Pro: $14/month, or $140/year (about $11.67/month), with unlimited clients
  • Enterprise: from $18/month for 1–2 users, up to $300/month for 51–100 users
  • Source code is published on GitHub, and a separate self-hosting option is offered
  • Connects to third-party payment gateways, so fees depend on the gateway you choose

Best suited for

Technical founders and agencies that want open-source software, custom branding, or self-hosting. It is also a strong low-cost upgrade path once you outgrow five clients.

4. PayPal Invoicing, best for customers who already pay with PayPal or Venmo

Free to create; fees on payment

PayPal Invoicing is the best choice when your customers already live in PayPal or Venmo. Creating and sending invoices is included with a business account, recipients do not need a PayPal account to pay, and recurring invoices and automatic reminders are built in. PayPal also syncs with QuickBooks and Xero.

Speed is PayPal’s strongest number. The company reports that 77% of PayPal invoices are paid within one day of sending, based on August 2023 to July 2024 data, and that more than 755 million invoices have been sent through the platform.

The cost is the highest in this list when customers pay from a PayPal or Venmo balance: 3.49% plus $0.49 per transaction, or about $35.39 on a $1,000 invoice. Card payments are cheaper at 2.99% plus $0.49. Bank payments are the bargain at 1% capped at $10, so large invoices paid by bank cost far less.

Key numbers

  • Creating and sending invoices: included with a PayPal account
  • PayPal and Venmo payments: 3.49% + $0.49 per transaction
  • Card and Apple Pay payments: 2.99% + $0.49 per transaction
  • Pay by Bank (ACH): 1%, capped at $10
  • PayPal reports 77% of its invoices are paid within one day of sending
  • Available in 200+ markets and 24 currencies

Best suited for

Freelancers and online sellers whose customers expect to pay with PayPal or Venmo, and anyone billing internationally across multiple currencies. Push large invoices toward the capped bank payment option to keep fees down.

5. Square Invoices, best for businesses already using Square for in-person sales

Free plan; Plus $20/month

Square Invoices makes the most sense when you already take in-person payments with Square. Invoices, customers, and payments live in the same dashboard as your point-of-sale sales, and the Free plan includes unlimited invoices, recurring invoices on daily to yearly schedules, batch invoices, estimates, and contracts.

On the Free plan, online card payments cost 3.3% plus $0.30, about $33.30 on a $1,000 invoice. Invoices Plus costs $20 a month after a 30-day trial and lowers the online card rate to 2.9% plus $0.30, adds payment schedules for deposits and milestones, and caps ACH transfer fees at $10. Plus pays for itself once you process roughly $5,000 a month in card invoices.

Square says businesses processing more than $250,000 a year can ask about custom pricing through Square Pro. Below that, the Free plan is a solid zero-subscription choice for service businesses.

Key numbers

  • Free plan: unlimited invoices, recurring invoices, estimates, and contracts
  • Plus plan: $20/month with a 30-day free trial, adding payment schedules and custom templates
  • Online card payments: 3.3% + $0.30 on Free, 2.9% + $0.30 on Plus
  • Plus caps ACH bank transfer fees at $10
  • Square Pro custom pricing for businesses processing over $250,000 a year

Best suited for

Retailers, salons, and trades businesses that already use Square hardware or software. It is also a good fit for contractors who need deposit and milestone schedules on the Plus plan.

6. FreshBooks, best for service businesses that bill hours and projects

From $23/month; 30-day free trial

FreshBooks is the most polished paid option for service businesses that bill by the hour or by the project. Time tracking, expenses, and project budgets roll straight into invoices, and clients can pay online by card or bank transfer.

It is not free. Lite lists at $23 a month for up to five billable clients, Plus at $43 a month for up to 50, and Premium at $70 a month with unlimited clients. FreshBooks regularly discounts the first months, and every plan starts with a 30-day trial that does not require a credit card.

Processing fees are competitive at 2.9% plus $0.30 for cards and 1% for bank transfers, about $29.30 on a $1,000 card invoice. The per-client pricing is what to watch: if you bill many small clients, you may hit the Lite or Plus caps quickly.

Key numbers

  • Lite: $23/month list price, 5 billable clients
  • Plus: $43/month, 50 billable clients
  • Premium: $70/month, unlimited billable clients; Select is custom-priced
  • Free trial: 30 days, no credit card required
  • Card payments: 2.9% + $0.30; bank transfers (ACH): 1%
  • Add-ons: team members $11/month per user

Best suited for

Consultants, agencies, and professional services firms that track time and want invoicing, expenses, and reports in one polished app. It is overkill for someone sending a few invoices a month.

Visit FreshBooks

7. Zoho Invoice, best for businesses already in the Zoho ecosystem

Free with annual usage limits

Zoho Invoice is a free invoicing app from Zoho, the business software company behind Zoho CRM, Zoho Books, and dozens of other apps. It includes estimates, recurring invoices, payment reminders, time tracking, and a customer portal, which is more than most free tools offer.

The limits are what to understand before you commit. Zoho’s own FAQ says the free plan supports one organization with a maximum of five invoiced customers, and the number of invoices you can create is governed by usage limits that Zoho updates every year. You can see your remaining allowance under Settings > Usage Stats.

Like Invoice Ninja, Zoho Invoice connects to outside payment gateways, so your fees depend on the gateway. If you outgrow it, Zoho Books is the natural upgrade and keeps your customer and invoice history.

Key numbers

  • Price: $0; Zoho describes Zoho Invoice as completely free
  • Free plan: one organization with up to 5 invoiced customers, per Zoho’s FAQ
  • Invoice allowance: set by yearly usage limits shown in Settings > Usage Stats
  • Includes estimates, recurring invoices, time tracking, and a customer portal
  • Card fees depend on the payment gateway you connect

Best suited for

Small teams that already use Zoho CRM or plan to move to Zoho Books later. It is a weaker fit for anyone billing more than five customers on the free plan.

What Results Look Like

Here is what each approach produces in practice, using each provider’s published numbers.

A $1,000 invoice, four ways

Paid by card, a $1,000 invoice nets $970.70 through FreshBooks, $970.40 through Wave Starter, $969.61 through PayPal card checkout, and $966.70 through Square Invoices Free. Sent as a PDF from the IncomeChecker.com generator and paid by bank transfer, it nets the full $1,000.

Faster payment with a pay link

PayPal reports that 77% of its invoices are paid within one day of sending, and Wave says customers who enable online payments get paid three times faster than cash or check. If speed matters more than fees, add a pay link.

A full paper trail for a landlord

A landlord bills one month’s rent plus a late fee with the invoice generator, then issues a rent receipt when payment arrives. Both documents match line for line, which keeps records clean for taxes or a deposit dispute.

Make the matching receipt
