The best free invoice generator in Australia depends on whether you need a PDF or a system: InvoiceSonic is the best overall because it creates, sends and tracks invoices for free, and Invoice-Generator.com.au is the best pure free tool because it produces an ATO-valid tax invoice with no signup and no watermark. We ranked ten invoice generators on three things nobody else checks: watermark on the free PDF, forced signup before download, and whether the document meets the ATO's tax invoice rules. Six of the ten failed at least one.
In a hurry? Use InvoiceSonic's free invoice generator if you want to send and track the invoice, or the Australian tax invoice generator here if you just need a clean GST-ready PDF in the next two minutes.
Quick comparison
"ATO tax invoice" means an ABN field, a GST line and a "Tax invoice" heading without editing the template. "No signup" means no account or email address to get the PDF. Where a vendor does not state its watermark policy, we say so rather than guess.

1. InvoiceSonic — Best overall
InvoiceSonic is free invoicing software that creates, sends and tracks a professional invoice from your phone or browser in under a minute. It suits sole traders, tradies and contractors. What sets it apart from every other free tool here is the after-work: an invoice tracker shows who has paid, and automatic reminders chase the ones who haven't.
It passes all three tests. Your first invoice needs no signup, there is no watermark, and the Australian tax format applies GST correctly (plus NZ, UK, US and Canadian formats across 12 currencies). It charges 0% transaction fee and gets you paid by bank transfer or PayID with no gateway to set up. It is free invoicing software built and supported by its founder, so a real person answers the support email.
Pros
- Sends, tracks and reminds — the three things a PDF generator cannot do.
- No signup for the first invoice, no watermark, 0% InvoiceSonic transaction fee.
- Saves your business name, logo and clients; recurring billing; iPhone app.
Cons
- You will eventually create an account to keep your invoice history.
- Invoicing only — no payroll, bank feeds or BAS; some automation sits on the Pro upgrade.
Price: Free tier with a Pro upgrade (see the site for current pricing). Best for: anyone sending more than a handful of invoices a month who wants to know who has paid.
2. Invoice-Generator.com.au — Best free tool
Invoice-Generator.com.au is a 100% free invoice generator that turns a form into a downloadable PDF with no signup, no watermark and no ads. It is built for people who need one correct document right now. What distinguishes it is privacy and compliance: invoice data never leaves your browser, and the Australian tax invoice generator adds an ABN field, 10% GST and a live checklist that ticks off each ATO requirement as you type.
It passes all three tests: no watermark, no signup, and the Australian mode produces a "Tax Invoice" heading with ABN and GST line. Totals calculate as you add lines and you can upload a logo. If you'd rather start from a layout, the tax invoice template and the profession-specific invoice templates (tradie, plumber, electrician, cleaner and more) come pre-filled.
Pros
- No account, no watermark, no ads, no invoice limit.
- ATO-valid tax invoice out of the box, with a compliance checklist; nothing stored on servers.
Cons
- It generates a PDF. It does not send, track or remind — you email the file yourself.
- No saved client list between sessions, and no payment links.
Price: Free, with no paid tier. Best for: a correct Australian tax invoice in two minutes, no strings attached.
3. Zoho Invoice free invoice generator — Best gateway to invoicing software
Zoho's free generator is a form-based builder that sits in front of Zoho Invoice, a genuinely free invoicing app for small businesses. It suits people who expect to outgrow a PDF. The distinguishing feature is the free plan behind it: up to 500 invoices a year, two users and three projects at no cost.
As a pure generator it is weaker. You can add a logo and a tax line, but the page prompts you to sign up to save and send, and custom fields (where an ABN would go) only exist inside the Zoho Invoice account. Watermark policy is not stated, and the stand-alone generator has no "Tax invoice" heading.
Pros
- The free Zoho Invoice plan is real: 500 invoices a year, reminders, recurring invoices, iOS and Android mobile app.
- Grows into expenses, timesheets and projects.
Cons
- Signup pushed at the download step; the generator is a lead magnet.
- No ABN field or "Tax invoice" heading on the stand-alone generator; watermark policy not stated.
Price: Free (generator and Zoho Invoice free plan); Zoho Books is paid — check current pricing. Best for: small businesses growing from a generator into invoicing software.
4. Wise invoice generator — Best for overseas clients
Wise's generator is a no-signup form that produces a PDF in any of its supported currencies. It suits Australian freelancers who invoice clients in the US, UK or Europe. The distinguishing feature is currency handling: you switch the invoice currency in a click.
No signup is required and Wise states you can create unlimited invoices. The tax field is generic (it talks about VAT), there is no ABN field and the heading is "Invoice", so an Australian tax invoice needs manual edits. Watermark policy is not stated.
Pros
- No signup, no stated invoice limit, instant PDF download.
- Invoice currency selectable per document; pairs with a Wise account for foreign payments.
Cons
- No ABN field and no "Tax invoice" heading.
- No sending, tracking or reminders; watermark policy not stated.
Price: Free. Best for: invoicing in USD, GBP or EUR to be paid into Wise.
5. Xero free invoice generator — Best if you're about to move to Xero
Xero's "free invoice generator" is an editable PDF template, not a web app: you enter your first name, email and country, and Xero emails you a fillable PDF with a how-to guide. The distinguishing feature is that you get both a tax and a non-tax version, so unregistered sole traders get the right document without a GST line.
It fails the signup test by design — the email form is the product. The tax version is built for Australian GST, so the fields line up with an ATO tax invoice. We could not confirm whether the PDF carries Xero branding. Because it is a fillable PDF, invoice numbers, dates and totals are manual.
Pros
- Tax and non-tax versions designed for Australian GST.
- Easy step to Xero proper for bank feeds, BAS and payroll.
Cons
- Email address required before you get anything.
- Static PDF with no automatic totals; a funnel to a paid Xero plan.
Price: Template is free; Xero subscriptions are paid — check current AUD pricing. Best for: a Xero-style tax invoice while you decide whether to buy Xero.
6. Square Invoices — Best for card payments on invoices
Square Invoices is a free invoicing app that sends unlimited invoices, estimates and contracts and takes card payments on them. The distinguishing feature is the payment link: the client pays by card from the invoice email, and Square settles to your bank next business day at no extra cost.
A Square account is required, so there is no anonymous download. PDFs are clean with no watermark. The Australian setup supports GST on invoices and prints your business details including ABN, so the result works as a tax invoice. The catch is the fee: 2.2% on online card payments at the time of writing, which is $110 on a $5,000 job. Bank transfer costs nothing.
Pros
- Free plan with unlimited invoices, estimates and contracts; tracks paid and unpaid.
- Card payment from the invoice; next-day transfer at no cost; mobile app.
Cons
- Account required.
- 2.2% online card fee; Invoices Plus AU$30 a month (at the time of writing).
Price: Free plan; Invoices Plus AU$30/month; 2.2% online card fee (at the time of writing). Best for: businesses that want "pay now" on the invoice.
7. Bookipi — Best mobile-first free tier
Bookipi is an invoicing app with free iOS and Android versions and a web generator, from the company behind Payroller. The distinguishing feature is the mobile app itself: logo, saved clients and default tax rates set once.
It needs a signup — the generator asks you to create an account to generate, send and save. The free plan is capped at 3 invoices a month (quotes count), so it is only free for very light use. Tax rates handle 10% GST, but an ABN field and "Tax invoice" heading are not called out. Pricing is in US dollars with 10% GST added.
Pros
- Solid mobile app; default tax rates and saved clients.
- Sends and tracks from the app; supports all currencies.
Cons
- Signup required; 3 invoices a month free.
- ABN field, "Tax invoice" heading and watermark policy not stated.
Price: Free (3 invoices/month); Starter US$9.99/month at the time of writing. Best for: phone-only sole traders sending fewer than 3 invoices a month.
8. Invoice Simple — Best quick app for one-line jobs
Invoice Simple is a web generator and mobile app aimed at contractors who want to invoice from the ute. The distinguishing feature is speed on a phone: pick a client, type a line, tap send.
We could not fully verify it — the Invoice Simple website blocks automated checks, so this section is based on public listings rather than a hands-on download. The generator builds an invoice with a tax line and logo, but free use is limited and the product steers you to a Premium subscription. There is no ABN field and watermark policy is not stated. Users report repeated price rises, so check the current price first.
Pros
- Fast on a phone; iOS and Android apps.
- Estimates, receipts and invoices in one app; sends and tracks on a plan.
Cons
- Limited free tier; Premium is paid — check current pricing.
- No ABN field or "Tax invoice" heading; free allowance not verifiable.
Price: Limited free use; paid plans available — check current pricing. Best for: one-line contractor invoices from a phone, if you're happy to pay.
9. Invoice Home — Best choice of designs
Invoice Home offers 100 invoice templates with a web and mobile app and PayPal or Stripe payment links. The distinguishing feature is the template library; nothing else here offers that many layouts.
An account is required (email, Google, Facebook, Yahoo or Microsoft), and the free plan lets you invoice up to $1,000 in a rolling 30-day window, which rules it out for most trades. Reviewers say the paid plan removes a watermark, which implies free PDFs carry one, but Invoice Home's own pages do not state it. There is no ABN field or "Tax invoice" heading. Unlimited is €5 a month at the time of writing.
Pros
- 100 invoice templates; logo and colour customisation.
- iOS and Android app; PayPal and Stripe payment links.
Cons
- Account required; $1,000 cap per 30 days on the free plan.
- Watermark on free PDFs reported by reviewers, not stated by the vendor; no ABN field.
Price: Free up to $1,000 invoiced per 30 days; Unlimited €5/month at the time of writing. Best for: occasional invoicers who want a designed look.
10. Wave invoice generator — Not for Australia
Wave's free invoice generator is a well-made form that ranks for Australian searches but is, in Wave's words, "currently available for US residents only". It is on this list so you don't waste ten minutes on it.
No account is needed to fill in the form, but you must enter an email to receive the PDF, which is a signup by another name. The tax field asks for "your state or province" rate, there is no ABN field and the heading is "Invoice". If you are in Australia, skip it.
Pros
- Clean layout, logo upload, tax rate field; free accounting behind it (US and Canada).
Cons
- US residents only, per Wave's own page.
- Email required for the PDF; no ABN, no GST label, no "Tax invoice" heading.
Price: Free. Best for: US freelancers; not Australians.
When not to use InvoiceSonic or a free generator
If you employ staff, you need payroll, super and STP reporting — that is Xero or MYOB territory. If you run a crew and the real problem is scheduling jobs and quoting on site, look at Tradify or ServiceM8, where the invoice falls out of the job card. And if a large customer requires e-invoicing over Peppol, none of the ten tools above sends Peppol e-invoices.
What to look for in a free invoice generator
- ATO tax invoice fields. A valid tax invoice must show the words "Tax invoice", your identity, your ABN, the invoice date, a description of what was sold, the GST amount, and the buyer's identity for sales of $1,000 or more. A tool without an ABN field makes you improvise. Our guide to tax invoice requirements in Australia covers each one.
- No watermark. Download a test PDF before you use any tool for real; six of the ten above do not state their policy.
- No forced signup. Only three tools here download with no account.
- Automatic calculations and sequential numbers. Line totals, GST and grand total should compute as you type, and the tool should make the invoice number and invoice date easy to set. See how to write an invoice for numbering rules.
- Saved business details and logo. Retyping your business name, ABN and BSB is how errors creep in; InvoiceSonic, Square and Bookipi save them.
- Custom fields, and a path to sending. Purchase order numbers and site addresses get invoices approved faster; check whether custom fields are free or gated. And if you send more than a few invoices a month, pick a tool that can email, track and remind.
Best free invoice generator for contractors
For contractors, the best free invoice generator is InvoiceSonic, with Invoice-Generator.com.au as the no-account fallback. Contractors get paid late more than most, so the invoice tracker and automatic reminders are worth more than any template. Its Australian GST format gives you a compliant tax invoice from a phone on site.
If you invoice once a month or don't want an account, the Australian tax invoice generator here does the job: choose Tax Invoice, add your ABN and 10% GST, and the checklist confirms the document meets the ATO's rules before you download. Skip Wave (US only), and think twice about Invoice Home's $1,000 monthly cap and Bookipi's 3-invoice limit — a working contractor blows through both in a week.
Which one should you choose?
- If you send fewer than 5 invoices a month and want zero commitment → the free invoice generator here. No account, no watermark, ATO-valid tax invoice.
- If you send more than 5 a month or have ever chased a late payment → InvoiceSonic. Free to start, tracks who has paid, reminds the rest.
- If clients want to pay by card from the invoice → Square Invoices, and price the 2.2% fee into larger jobs.
- If you want a free app that grows into expenses and projects → Zoho Invoice's free plan, and accept the signup.
Frequently asked questions
What is the best free invoice generator in Australia?
For a one-off PDF, Invoice-Generator.com.au: no signup, no watermark, and its Australian mode produces a tax invoice with an ABN field, 10% GST and a "Tax Invoice" heading. If you also need to send, track and chase invoices, InvoiceSonic is the better free tool because it does all of that at no cost.
Do free invoice generators add a watermark?
Some do, and most don't say so until you download. InvoiceSonic and Invoice-Generator.com.au both state there is no watermark. None of the eight third-party tools here states a no-watermark guarantee, so download a test PDF and check the footer first.
Is a free invoice generator's PDF a valid tax invoice for the ATO?
Only if the PDF shows the words "Tax invoice", your identity and ABN, the invoice date, a description of what you sold, the GST amount, and the buyer's identity for sales of $1,000 or more. Invoice-Generator.com.au's Australian mode and InvoiceSonic's Australian GST format cover these; several overseas generators do not have an ABN field at all.
Do I need to register for GST before I can issue a tax invoice?
Yes. You can only issue a tax invoice and charge 10% GST once you are registered for GST, which is compulsory once your turnover reaches $75,000 a year. Below that you can still invoice, but the document should be titled "Invoice", not "Tax invoice", and it should not show a GST line.
Which free invoice generator works without signing up?
Invoice-Generator.com.au, Wise and InvoiceSonic (for your first invoice) let you build and download a PDF with no account. Zoho Invoice, Bookipi, Square, Invoice Home and Xero all ask for an email address or an account before you get the file.
Can I use a free invoice generator on my phone?
Yes. InvoiceSonic has an iPhone app and works in a mobile browser; Bookipi, Invoice Simple, Invoice Home and Square have iOS and Android apps. Invoice-Generator.com.au is a responsive web page, so it works on a phone without installing anything.
