The short answer: the best free invoicing software for most small businesses is Zoho Invoice — genuinely $0 forever, with the fullest free feature set, capped at 500 invoices a year for up to 2 users. The better pick if you also want bookkeeping behind your invoices is Wave Starter — $0 with unlimited invoices and no revenue ceiling, but US and Canada only, and automatic payment reminders wait behind its $19-a-month Pro plan. Square Invoices Free is best if clients pay you in person as well as online, with unlimited invoices at $0 in a single account. Behind them sit Invoice Ninja Free (best for a freelancer with a handful of clients), QuickBooks Free (best free bank feed, smallest free allowance), and Zoho Books Free (best if invoicing is the front door to full accounting). The rest of this guide ranks all six by the two things that actually decide a free invoicing pick: the processing fee you pay on every paid invoice, and the cap that ends your free run.
Affiliate disclosure. We do not have affiliate partnerships with any of these vendors yet, so every link in this article is a plain link to the vendor’s own site — nobody pays us for clicks or signups, and payments would not change what we recommend anyway. If we add affiliate programs later, this article will be updated to say so. How we handle this site-wide is on our /disclosure/ page.
If invoicing is only part of the job and you want the paid side compared too — including FreshBooks, Stripe, and the accounting suites — our invoicing software guide covers that ground. If you want free bookkeeping to go with free invoicing, our free accounting software guide ranks the free ledgers. This article answers the narrower question: which invoicing tool costs $0, for whom, and where does “free” stop?
How free invoicing software actually works: two prices, not one
An invoicing vendor has two ways to get paid, and every free plan uses at least one of them:
1. The processing fee. When a client pays an invoice by card, the vendor (or your gateway) takes a percentage plus a fixed fee. This is the real price of “free” invoicing, and it dwarfs any subscription. On $10,000 of card-paid invoices in a month, Wave takes ≈ $290 plus per-transaction fixed fees, Square Free takes ≈ $333, and Zoho Invoice passes through your gateway’s rate — with Stripe, ≈ $290 plus fixed fees. A free plan that charges 3.3% instead of 2.9% costs you an extra $40 on every $10,000 of card payments, every month, forever. That is why the fee column in the table below matters more than the $0 in the price column.
2. The cap. A free plan is engineered to be genuinely usable and to run out of room exactly where growth happens. Vendors cap volume (Zoho Invoice: 500 invoices a year), people (Wave Starter: owner only; Zoho Invoice: 2 users; Invoice Ninja Free: 5 clients), or automation (Wave holds reminders and bank imports for Pro; Square holds its lower card rate and ACH fee cap for Plus). The cap you hit first decides your pick — and the first paid tier behind it is the real price of admission.
The first-principles consequence: never compare free invoicing plans on their $0 price. Compare them on (a) the fee your clients’ payment method triggers, and (b) the cap that binds first for your business — and what the first paid tier behind that cap costs. Bank payments are the cheapest lane everywhere: Wave charges 1% (minimum $1) for bank payments, Square Free charges 1% with no cap, and Stripe through Zoho Invoice charges 0.8% capped at $5. If your clients pay $2,000 invoices by bank instead of card, you save roughly $38 to $46 per invoice. That single habit beats every plan choice in this article.
When free stops being enough
Four moments end most free-invoicing runs, usually within the first year:
- You cross a volume or client cap. Invoice 501 in a year ends Zoho Invoice’s free run. Client 6 ends Invoice Ninja Free’s cloud plan. Invoice 3 in a month ends QuickBooks Free’s usefulness (unless QuickBooks Payments lifts it).
- A second or third person needs in. Wave Starter is owner-only — no invited users at $0. Zoho Invoice stops at 2 users. Adding a bookkeeper, a partner, or an admin ends both.
- You need automation the free plan holds back. Automatic payment reminders need Wave Pro ($19 a month) — Zoho Invoice and Square include reminders free, which is a genuine point in their favour. Automatic bank feeds need QuickBooks Free (the only free plan with one) or a paid accounting tier.
- You need accounting, inventory, or payroll behind the invoices. No invoicing-only free plan does these properly. That is the moment to step up to a paid invoicing tool or a full accounting suite.
When any of these arrives, the first paid tiers are:
| Vendor | First paid step | Price per month |
|---|---|---|
| Zoho Invoice | No paid invoicing tier — upgrade is Zoho Billing Standard | $25 per organization (annual) |
| Wave | Pro | $19 (monthly) / $190 per year |
| Square Invoices | Plus, per location | $49 |
| Invoice Ninja | Pro (cloud) | $14 (monthly) / $140 per year |
| QuickBooks Online | Simple Start | $38 |
| Zoho Books | Standard | $15 (annual) / $20 (monthly) |
Note the odd one out: Zoho Invoice has no paid version of itself. Outgrowing it means moving to a different Zoho product (Zoho Billing for subscriptions, or Zoho Books Free/Standard for accounting) — a migration, not an upgrade. If you expect to pass 500 invoices a year soon, Wave’s unlimited invoices with a $19 Pro ladder may be the cheaper long-term bet despite its thinner free feature set. For the paid-side math, see our invoicing software guide and our accounting software cost guide.
The contenders, fee by fee and cap by cap
Prices below are US list prices researched on 2026-10-31 from each vendor’s own pricing page, cross-checked against current third-party pricing breakdowns from October 2026. Processing rates change — Square and Wave have both moved theirs in the last two years — so re-check the pricing page before you commit.
Zoho Invoice — best free invoicing software for most businesses
Zoho Invoice is the free plan we would hand a new business by default, because it is the only one here where “free” is the whole product rather than a tier. The single plan costs $0 — no subscription, no card, no paid invoicing tier waiting behind it — and it covers quotes, invoices, recurring invoices, expenses, automated payment reminders, a self-service client portal, and reports.
The limits, stated plainly on Zoho’s own pricing page: 500 invoices a year, 2 users, 3 projects, 2 organizations, with “Powered by Zoho Invoice” branding on your invoices. Payment processing is your gateway’s rate, not Zoho’s — connect Stripe and you pay Stripe’s 2.9% + $0.30 on cards and 0.8% capped at $5 on bank payments. One more term worth knowing: Zoho notes that data from an account inactive for over 180 days is deleted within the following 20 days, so this is not a park-it-and-forget-it archive. There is no paid Zoho Invoice tier; the named upgrade for subscription billing is Zoho Billing Standard at $25 per organization per month billed annually, and the accounting step up is Zoho Books (free under $50,000 revenue, Standard from $15 billed annually).
Best for: a freelancer or two-person business sending under 500 invoices a year that wants the fullest free feature set — reminders, portal, recurring billing — at $0 forever.
Wave — best free invoicing plus free bookkeeping
Wave is the free plan for a business that wants the invoice and the ledger at $0. The Starter plan costs $0 with no time limit, no revenue ceiling, and no cap on invoices, estimates, bills, customers, or bookkeeping records, with real double-entry accounting underneath. That combination — unlimited invoicing plus free bookkeeping — is unmatched in this roundup.
The catches, and they matter. First, Wave serves the US and Canadian market only. Second, Starter is owner-only: invited users need Pro. Third, automatic payment reminders need Pro — the one automation gap that stings for an invoicing tool, since chasing payment is half the job. Fourth, since June 2026, automatic bank transaction imports are a Pro feature — Starter users upload statements by hand. Wave’s revenue model is visible and fair: card payments taken through a Wave invoice cost 2.9% + $0.60 per transaction (3.4% + $0.60 for American Express), bank payments cost 1% (minimum $1), and Pro is $19 per month or $190 per year, adding reminders, automatic bank imports, receipt capture, and multi-user roles.
Best for: a solo owner or freelancer in the US or Canada who invoices clients, wants free bookkeeping behind the invoices, and can live without automatic reminders until the business justifies $19 a month.
Square Invoices — best free invoicing if clients also pay in person
Square is the free plan for a business whose clients sometimes pay at a counter, a market stall, or a job site — not only online. The Free plan costs $0 with unlimited invoices, estimates, and contracts, unlimited users, and unlimited customers, sent by email, text, or link, with recurring invoices included. One Square account covers online invoices and in-person card sales together, which no other free plan here does.
The catch is the card rate. Online invoice card payments on Free cost 3.3% + $0.30 — the highest card rate in this roundup — and bank (ACH) payments cost 1% with no cap on Free. Plus, at $49 per month per location, drops the online card rate to 2.9% + $0.30 and caps the ACH fee at $10. The arithmetic is blunt: the 0.4-point card saving covers the $49 fee only once you pass ≈ $12,250 of card invoices a month, but the ACH cap pays for itself much sooner if you take large bank payments — a $2,000 ACH invoice costs $20 on Free versus $10 on Plus. If most of your clients pay by card, Square Free is the most expensive “free” plan here; if they pay in person or by bank, it is one of the best.
Best for: a contractor, retailer, or service business that takes payments in person as well as online and wants one free account for both.
Invoice Ninja — best free invoicing for a freelancer with a handful of clients
Invoice Ninja is the free plan for a freelancer whose client list is short and stable. The cloud Free plan costs $0 with unlimited invoices, recurring billing, time tracking, and 40+ payment gateway integrations — the widest gateway choice here, so you are not locked into one processor’s rate.
The catch is the client cap: the current cloud free plan covers up to 5 clients (older reviews cite 20 — that figure is out of date as of October 2026). Client 6 ends the free run, and the step up is Pro at $14 per month ($140 per year) for unlimited clients. The escape hatch is self-hosting: install Invoice Ninja on your own server and the free version has no client or invoice caps at all — with the installation, updates, backups, and security work that implies. If you would rather not run a server, the hosted Pro price is the cheapest paid step in this roundup.
Best for: a freelancer with 5 or fewer regular clients who wants recurring billing, time tracking, and gateway choice at $0 — or a technically comfortable owner happy to self-host with no caps.
QuickBooks Free — best free bank feed, smallest free allowance
QuickBooks Online added a genuine free tier in September 2026, and it is the only free plan here with an automatic bank connection (1 bank account). The Free plan costs $0 for 1 user, with income and expense tracking, 2 invoices a month, 1 estimate a month, 2 receipt uploads a month, and 3 core reports (profit and loss, balance sheet, account quick report).
The catches are why it ranks fifth despite the bank feed. There is no accountant access, no mobile app, and no third-party integrations on Free. The 2-invoice monthly cap ends its usefulness for almost any operating business, unless you qualify for and enable QuickBooks Payments, which lifts the invoice cap. And Intuit notes Free “may be offered for a limited time,” so treat it as a current offer, not a permanent promise. The first paid tier with accountant access is Simple Start at $38 per month (1 user plus 2 accountants) — the most expensive first step in this roundup, but also the one that buys a full accounting suite rather than just invoicing.
Best for: a side business sending 1–2 invoices a month, with no accountant, that values an automatic bank feed above everything else — or a business already planning to land on QuickBooks paid.
Zoho Books Free — best free invoicing that grows into accounting
Zoho Books is the free plan for a business that wants invoicing today and a real ledger tomorrow without migrating. The Free plan costs $0 while your annual revenue stays at or below $50,000, and it covers 1 user plus 1 accountant, up to 1,000 invoices and 1,000 expenses a year, 50 receipt autoscans a month, 50+ reports, and bank reconciliation by statement import. Unlike Wave Starter, your accountant gets in free; unlike Zoho Invoice, you get double-entry accounting underneath.
The catches: the $50,000 revenue ceiling is a cliff, not a slope — cross it and you need Standard. Automatic bank feeds are not on Free; they start on Standard at $15 per month billed annually ($20 billed monthly), which also raises you to 3 users. And if invoicing alone is all you need, Zoho Invoice’s reminders-and-portal feature set is richer at the same $0 — Zoho Books Free trades some invoicing polish for accounting depth. Full detail is in our free accounting software guide.
Best for: a very small business under $50,000 revenue that wants its accountant in the file, fuller reports than Wave, and a paid ladder it can climb without migrating.

Three products that look free but are not
Worth a short section because all three rank well for this query and all three cost money from day one:
- FreshBooks — no free tier, only a 30-day trial. Lite starts at $23 per month and caps you at 5 billable clients; most service businesses need Plus at $43. A strong invoicing tool, but $0 is not on its menu.
- Xero — no free tier, only a 30-day trial. Early starts at $27 per month (20 invoices, 5 bills), Growing at $59, Established at $97. A strong accounting suite, but again, $0 is not on its menu.
- Harvest — often listed as “free invoicing,” but its free tier is a time-tracking plan (1 seat, 2 projects) with invoicing attached, and Pro starts at $11 per seat per month billed annually. Fine if you bill by the hour; not an invoicing-first free plan.
The verdict: best for each business shape
Freelancer or two-person business, under 500 invoices a year, budget zero: Zoho Invoice. The fullest free feature set — reminders, portal, recurring billing — at $0 forever, with the cleanest cap to plan around.
Solo owner, invoicing clients, wants free bookkeeping too: Wave Starter. Unlimited invoices at $0 with no revenue ceiling, provided you are in the US or Canada and can live without automatic reminders until Pro.
Clients pay in person as well as online: Square Invoices Free. Unlimited invoices in one account for both — but steer card payers to bank payments, or the 3.3% card rate will quietly become your most expensive “free” plan.
Freelancer with 5 or fewer regular clients: Invoice Ninja Free. Unlimited invoices, recurring billing, and gateway choice at $0 — or self-host it and drop the client cap entirely.
Side business, 1–2 invoices a month, bank feed matters most: QuickBooks Free — but confirm it is still offered, and have a Simple Start budget ($38) ready for the month you outgrow it.
Under $50,000 revenue, accountant in the file, planning to grow into accounting: Zoho Books Free, then Standard at $15 billed annually when revenue or headcount crosses the line.
Before you decide, run these three checks: (1) count your invoices and your clients next year, not this month — the volume cap and the client cap are the two most common surprises, and different tools cap different things; (2) check how your clients actually pay — a card-heavy business should weight the processing fee above every feature, and a bank-payment habit beats every plan choice; (3) price the first paid tier, not the free one, because the exit is the real decision.
For the paid-side comparison — including FreshBooks, Stripe, and the accounting suites — see our invoicing software guide and the accounting category hub. And if free bookkeeping matters as much as free invoicing, our free accounting software guide ranks the ledgers that cost $0.
Prices checked 2026-10-31 from vendor pricing pages, cross-checked against current third-party pricing breakdowns from October 2026. Free-plan limits change often — Invoice Ninja’s cloud client cap has already moved from 20 to 5 in recent years, Wave moved bank imports to Pro in June 2026, and QuickBooks Free arrived in September 2026 with a limited-time note — verify your exact tier on the vendor’s pricing page before committing.
