Here is the problem with most "free" invoicing tools: they are free until you actually want to get paid. Then a 2.9% transaction fee shows up, or a client cap locks you out, or the feature you need is behind a $19/month paywall. The word "free" is doing a lot of heavy lifting in this category.
The best free invoicing tools let freelancers create, send, and track invoices without a subscription fee. Top options include Wave, Grey, Invoice Ninja, and PayPal. Each has different strengths: Wave suits sole traders doing basic accounting; Grey suits freelancers paid in multiple currencies; Invoice Ninja suits those who need recurring invoices and time tracking.
This guide cuts through the marketing. Eleven tools, ranked by what they genuinely offer at zero cost, where the charges start, and which type of freelancer each one actually fits. The best invoicing software for freelancers is not the one with the longest feature list. It is the one that matches the way you bill.
What to Look for in a Free Invoicing Tool
Before you compare tools, get clear on what "free" actually means in online invoicing for small business contexts. There are three models, and they are not the same thing:
Model 1: Free to send, fees on payment. This is Wave, PayPal, and Stripe. You never pay a subscription, but when a client pays your invoice through the platform, the tool takes a cut. Wave charges 2.9% + $0.60 per card payment. PayPal charges up to 3.49% + a fixed fee. On a $3,000 invoice, that is $87 to $105 gone before the money reaches you. These fees are comparable to what Stripe charges directly, so you are not overpaying, but you are not invoicing for free either.
Model 2: Free up to a limit. Zoho Invoice gives you 1,000 invoices per year for free. Invoice Ninja and Hiveage cap the number of clients on their free plans. These tools are genuinely free if you stay within the ceiling. Once you outgrow it, you pay, or you switch.
Model 3: Free invoicing, paid for other features. Grey and Canva fall here. Invoicing is free because the product earns revenue elsewhere (multi-currency accounts, design subscriptions). No per-invoice fee, no payment processing cut, no client cap on the invoicing feature itself.
Beyond the pricing model, four things matter: whether the tool supports the currencies your clients pay in, whether it sends automatic payment reminders (the single biggest lever for getting paid on time), whether it connects to your accounting software, and whether the free plan stamps the tool's branding on your invoices.
The 11 Best Free Invoicing Tools for Freelancers
Ranked by the strength of their free offering. Paid tools are included only where the trial or all-in-one value genuinely earns a spot. If a tool calls itself free but charges per payment, that is noted up front.
1. Wave
Wave is the tool most freelancers should start with, and many never leave. It is genuinely free: unlimited invoices, unlimited clients, no time limit, no "starter plan" that expires after 30 days. You get invoicing, basic double-entry accounting, receipt scanning, and financial reports without paying a cent. Wave makes money when clients pay through its payment processing (2.9% + $0.60 per card, 1% per ACH). If your clients pay by bank transfer outside Wave, you pay nothing at all.
Use it if: you want invoicing and bookkeeping in one place without spending anything. Skip it if: you need time tracking (Wave does not have it) or you bill in multiple currencies and want to hold those currencies (Wave converts everything).
2. Grey
Grey is the pick for freelancers whose clients pay in different currencies. You create an invoice in USD for your New York client and another in GBP for your London client, and both payments land in your Grey account in those currencies. No forced conversion, no bank markup, no surprise fees on arrival. Invoicing is free and built into the account. Grey earns its revenue from the multi-currency account and virtual card products, not from invoicing. See Grey invoicing for freelancers and get paid from the US.
Use it if: you have international clients paying in USD, GBP, or EUR, and you are tired of losing 2 to 3% on every conversion. Skip it if: you only bill domestic clients in one currency (Wave is simpler for that).
3. Invoice Ninja
The developer's choice. Invoice Ninja is open-source, which means you can self-host it on your own server for free with no limits at all. The hosted cloud version has a free tier with a client cap (check invoiceninja.com for the current number). Either way, you get invoices, quotes, recurring billing, time tracking, a client portal, and over 250 payment gateway integrations.
Use it if: you want full control over your data, or you need time tracking baked into your invoicing workflow.
Skip it if: you are not comfortable with the technical setup (Wave or Grey is more plug-and-play).
4. Zoho Invoice
Zoho gives you 1,000 invoices per year for free, which is roughly 80 per month. That is more headroom than most solo freelancers need. The free plan includes recurring invoices, automated payment reminders (email and SMS), a client portal, time tracking, expense tracking, and multi-currency support. It connects to Zoho Books and the broader Zoho ecosystem if you grow into it.
Use it if: you want polished automation (scheduled sends, automatic follow-ups) without paying, and you might eventually use Zoho's other business tools.
Skip it if: you want something simpler (Zoho's interface can feel heavy for basic invoicing).
5. FreshBooks
FreshBooks is not free. The Lite plan costs $19 per month after a 30-day trial. It is on this list because the invoicing experience is the best in the category, and it is worth knowing what the paid benchmark looks like before you commit to a free tool. Five billable clients, unlimited invoices, time tracking, expense tracking, automatic reminders, and a client portal with a polished "Pay Now" button. An invoice takes 30 seconds to create, and the client gets a professional page, not a PDF attachment.
Use it if: you bill 5 to 30 clients and value UX enough to pay $19/month for it.
Skip it if: you are on a strict $0 budget (use Wave) or you need multi-currency without conversion (use Grey).
6. PayPal Invoicing
PayPal's strength is not the invoicing tool itself. The fact is that nearly every business on the planet can pay a PayPal invoice without signing up for anything new. You create the invoice inside PayPal, the client pays with their PayPal balance, a card, or a bank account, and the money lands in your PayPal account. Free to send. PayPal charges up to 3.49% + a fixed fee when the client pays. On a $5,000 invoice, that is roughly $175.
Use it if: your clients are in multiple countries and you want the lowest-friction payment method they already recognise.
Skip it if: your invoices are consistently large. At $175 per $5,000 invoice, PayPal's fees add up fast.
7. Bonsai
Bonsai is $21 per month (Starter), so it is not free. But it is here because it replaces five separate tools: invoicing, CRM, proposals, contracts with e-sign, and time tracking. If you would otherwise be paying for Wave ($0) plus Calendly ($12) plus DocuSign ($25) plus a proposal tool ($25), Bonsai at $21/month is the cheaper option. The invoicing module alone is not as slick as FreshBooks, but the all-in-one package is hard to beat.
Use it if: you manage 5 to 20 clients and want proposals, contracts, and invoicing in one place.
Skip it if: invoicing is all you need (Wave or Zoho is simpler and free).
8. Canva Invoice
Canva is the simplest free invoice generator on this list, and also the most limited. You pick an invoice template, customise it with drag-and-drop, export as a PDF, and email it yourself. No payment link, no automatic reminders, no tracking, no accounting integration. What it does have: the most visually polished invoice you can send for free. If you are a photographer, designer, or creative whose clients care about brand presentation, a Canva invoice looks better than anything auto-generated by a billing tool.
Use it if: you send fewer than 5 invoices per month and want full visual control.
Skip it if: you need any automation, tracking, or payment processing.
9. Harvest
Harvest is a time tracker first and an invoicing tool second, and that is exactly why it is good. The free plan covers 1 user and 2 projects. Pro is $13.75 per month per seat. The killer feature: you track your hours, click "Create Invoice," and the invoice auto-populates from your logged time. No re-entering hours, no maths, no mistakes. It integrates with Stripe, PayPal, QuickBooks, Xero, and Asana.
Use it if: you bill hourly and want tracked time to flow directly into invoices.
Skip it if: you bill flat-rate or retainer (FreshBooks or Bonsai covers more of that workflow).
10. Stripe Invoicing
If you already use Stripe for payments, adding invoicing takes two minutes. No subscription. Stripe charges 0.4% per paid invoice on top of standard processing (2.9% + $0.30 per card). The invoices are basic: line items, a payment link, and automatic receipts. No time tracking, no recurring automation worth mentioning, no accounting features. It is the simplest path from "I need to bill someone" to "they paid."
Use it if: you send fewer than 10 invoices per month and already live inside Stripe.
Skip it if: you need anything beyond a payment link with line items.
11. Hiveage
Hiveage is the quiet pick for retainer-based freelancers. Free plan available with limits on clients and invoices (check hiveage.com for current terms). It handles recurring invoices, time and expense tracking, multi-currency support, and a client portal. The interface is clean and minimal. Set the billing schedule once, and invoices go out automatically every cycle. No fuss, no complexity.
Use it if: you are on monthly retainers and want set-and-forget billing.
Skip it if: you need time-to-invoice conversion (Harvest is better) or full accounting (Wave is better).
How to Send Your First Invoice as a Freelancer
Whether you use a dedicated invoicing platform or a simple free invoice generator like Canva, every invoice needs the same core information. Miss any of these, and you either look unprofessional or delay your own payment, or both.
- Your full name or business name, address, and contact details. This is the "from" section. If you operate under a business name, use it. If you are a sole proprietor using your personal name, that is fine too.
- Your client's name, company name, and billing address. Get this right. A misspelt company name on an invoice can delay processing in larger organisations where accounts payable matches invoice details against purchase orders.
- A unique invoice number. Start at 001 or INV-001 or whatever system you will maintain consistently. Sequential numbers make it easier to track what has been paid, what is outstanding, and what to report at tax time.
- The invoice date and the payment due date. Do not just write "Net 30." Write "Net 30, due 15 October 2026." A specific date creates a deadline. A payment term creates a calculation that the client will not do.
- An itemised list of services with rates and totals. If you bill hourly, show the hours and the rate. If you bill per project, describe the deliverable and the agreed price. Be specific enough that the client can match the invoice to the work without having to ask questions. For guidance on setting rates, see how to set your freelance rates.
- The total amount due, including any applicable taxes (sales tax, VAT, GST, depending on your jurisdiction).
- Your payment details. Bank account number, routing number or sort code, PayPal address, or a direct payment link. Include the currency. If your client is in a different country, give them the details in their local payment format so they do not have to figure it out.
- Late payment terms. "A fee of 1.5% per month applies to invoices overdue by more than 14 days." Stating this on the invoice (not buried in a contract) significantly improves on-time payment rates.
Getting Paid Faster: What to Put on Your Invoice
The gap between getting paid in 7 days and getting paid in 47 days is almost never about the client's intent. It is about the invoice. Four changes make a measurable difference:
Put a real date on it, not just a payment term. A client who reads "Due 15 October" feels a deadline. A client who reads "Net 30" has to do maths they will not do. Both should appear, but the date is what drives action.
Embed a payment link in the invoice PDF. Every extra step between reading the invoice and completing the payment is a point where the client thinks, "I will do this later." A one-click payment link inside the PDF itself removes all of them.
Invoice in your client's currency. If a US client receives an invoice in GBP, they have to calculate the conversion, wonder about the exchange rate, and navigate their bank's international transfer process. Invoice them in USD, and they pay in five minutes. Grey invoicing for freelancers lets you create invoices in USD, GBP, or EUR and receive the payment in that same currency. If your US clients need a W-8BEN before they can pay you, see how to complete a W-8BEN for US clients.
Put your late payment terms on the invoice, not in a separate contract. The invoice is the document that the accounts payable team actually sees. If the late fee is only in your contract, nobody in the payment queue reads it. Put it where it counts. For a full setup to receive international payments, open a Grey account to receive international payments.
Request a deposit before starting work on new or large projects. A 25 to 50% deposit upfront protects you from non-payment, filters out clients who are not serious, and gives you working capital during the project. State the deposit requirement in your proposal, and send the deposit invoice before you begin.
Open a Grey account and send professional invoices in any currency, for free, from the same place you receive your payments.
Frequently Asked Questions
What is the best free invoicing app for freelancers?
It depends on your situation. Wave if you want free invoicing plus free accounting in one tool. Grey if your clients pay in multiple currencies and you want to hold those currencies without forced conversion. Invoice Ninja, if you are technical and want open-source software, you can self-host. PayPal if you just need the fastest way to bill international clients who already have PayPal accounts. There is no single "best" because invoicing needs vary wildly by billing volume, client geography, and what else you need the tool to do.
How do I handle taxes if I use a free invoicing tool?
Free invoicing tools track what you billed and what you received. They do not calculate, set aside, or file taxes for you. In the US, you need to make quarterly estimated tax payments to the IRS, typically 25 to 30% of your net freelance income. In the UK, self-assessment requires you to save for an annual tax bill plus payments on account. Wave is the only free tool on this list that includes basic accounting to help with tax preparation. Tools like Zoho Invoice and FreshBooks integrate with TurboTax and QuickBooks. But no free invoicing tool files your taxes. Set aside tax money in a separate account from your first invoice.
Can I invoice clients without a registered business?
Yes. In both the US and the UK, you can invoice as a sole proprietor or sole trader without registering a company. Your invoice should include your legal name, address, and tax identification number where required (Social Security number or EIN in the US, National Insurance number in the UK). Some US clients will ask for a W-9 before processing your first payment.
What invoicing tool is best for international clients?
Grey, if you want to invoice and receive in the client's currency without conversion. PayPal, if your clients already have PayPal accounts and you want the lowest-friction option (but watch the fees: up to 3.49% + fixed per transaction). Zoho Invoice supports multi-currency on its free plan, but relies on third-party payment processors to actually collect the money. For large or recurring international invoices, Grey's approach of holding multiple currencies saves more over time than PayPal's convenience.
Do I need accounting software if I just use an invoicing tool?
Not right away, but you will eventually. Invoicing tracks what you billed. Accounting tracks what you spent, what you owe in taxes, and whether you are actually profitable. Wave bridges this gap by bundling free accounting alongside free invoicing, which is why it is the default recommendation for freelancers just starting out. Beyond roughly $30,000 per year in freelance income, connecting your invoicing tool to QuickBooks, Xero, or Zoho Books saves real time at tax season. See Grey for freelancers for how Grey fits into a broader financial setup.
