Best Free Invoice App in Australia (2026): 10 Compared
Compare 10 free invoice apps available in Australia in 2026 — real free tiers, hidden caps, GST compliance, and which ones Australians can't actually use.
Short answer: for most Australian sole traders and small businesses, the best free invoice app in 2026 is Zoho Invoice if you want a full free account (1,000 invoices a year, genuinely free), Square Invoices if you need to take card payments, and InvoiceSonic if you want an ATO-compliant tax invoice without creating an account at all. There is no single winner — the right pick depends on whether "free" needs to mean no account, no monthly fee, or no payment fees.
Below is what each app actually costs once you read the fine print, and the one trap that catches Australian businesses specifically.
The trap: half the "best free invoice app" lists still recommend Wave
Wave is the most-recommended free invoicing tool on the internet. It stopped accepting sign-ups from outside the United States and Canada in November 2020.
If you are in Australia and you follow a 2026 listicle to Wave, you will reach a sign-up form you cannot complete. Several Australian roundups still list it. Check the publication date and check the vendor's own eligibility page before you invest an afternoon migrating.

The three meanings of "free"
Most disappointment with free invoicing apps comes from not noticing which kind of free you're being offered.
Free as in no monthly fee, but you pay per payment. Square and PayPal are the clearest examples. Sending is free forever; you pay 2.2% (Square) or 2.6% + A$0.30 (PayPal) each time a client pays by card. On a A$3,000 invoice that's A$66 to A$78. If your clients pay by bank transfer, you pay nothing — which is why so many Australian sole traders quietly use these tools as free invoice generators and never turn on card payments.
Free as in capped. Zoho gives you 1,000 invoices a year, Invoicely gives you 3 clients and 5 invoices a month. Caps are fine until you grow into them mid-quarter.
Free as in branded. Zervant, Refrens and Inv24 put their own name on your invoice. That's a real cost if you're trying to look established — it's the single most common reason people upgrade.
Free as in no account. This is the rarest. Most tools require sign-up before you can download anything. InvoiceSonic's generator lets you fill in a tax invoice and download the PDF without creating an account, with no watermark. Signed-in free accounts save 3 invoices a month; unlimited saving is Pro at A$19/month.
What an Australian invoice actually has to include
Whichever app you choose, an ATO-compliant tax invoice for sales over A$82.50 (including GST) needs:
- The words "Tax Invoice"
- Your business name and ABN
- The date
- A description of what you sold, with quantities
- The GST amount for each item, or a statement that the total includes GST
- The buyer's identity or ABN for sales over A$1,000
If you're not registered for GST, you must issue a plain invoice, not a "tax invoice", and you must not charge GST. Getting this wrong is the most common problem accountants report with new sole traders' books. Our ABN invoice template has both modes built in.
International apps often can't do this properly. Zoho, Square and Invoice2go handle GST fine. Some smaller European tools only offer a generic "VAT" field with no ABN line — check before committing.
Which should you actually pick?
If you invoice occasionally and hate signing up for things: use a no-account generator. You'll have a compliant PDF in about a minute.
If you invoice regularly and want a free account: Zoho Invoice has the best genuine free tier available in Australia. 1,000 invoices a year is more than most sole traders will ever send.
If getting paid fast matters more than fees: Square Invoices. Clients can pay by card from the invoice itself, and the 2.2% often pays for itself in reduced chasing.
If you're a tradie quoting on site: Invoice2go or Billdu — both are mobile-first and cheap, and both handle quotes as well as invoices.
If you want your accountant to stop complaining: you probably need bookkeeping, not just invoicing. See our guide to accounting software for sole traders.
Where InvoiceSonic fits — and where it doesn't
We build InvoiceSonic, so treat this section accordingly.
It's a good fit if you want an ATO-compliant tax invoice quickly, without an account, with ABN and GST handled properly, and no watermark on the PDF. Free covers creating and downloading; a free account saves 3 invoices a month; Pro is A$19/month or A$168/year for unlimited.
It's the wrong tool if you need bank reconciliation, BAS lodgement, payroll, or expense tracking. That's Xero, MYOB or QuickBooks territory and we don't pretend otherwise — see InvoiceSonic vs Xero for an honest breakdown. It's also the wrong tool if you want card payments collected inside the invoice today; Square is better at that right now.
Frequently asked questions
What is the best completely free invoice app in Australia?
Zoho Invoice, for a full free account — 1 user and 1,000 invoices per year with no fee and no branding. For one-off invoices without signing up, a browser-based generator is faster.
Can I use Wave in Australia?
No. Wave stopped accepting sign-ups outside the US and Canada in November 2020. Existing accounts were affected by later changes too. Ignore any 2026 list that still recommends it to Australians.
Do free invoice apps produce ATO-compliant tax invoices?
Some do. You need the words "Tax Invoice", your ABN, and a GST breakdown. Zoho, Square, Invoice2go and InvoiceSonic all handle this. Generic international tools often don't include an ABN field.
Is a free invoice app good enough for a sole trader?
Usually yes. Most sole traders send fewer than 20 invoices a month, which fits inside several free tiers. You outgrow free when you need recurring invoices, automated payment reminders, or more than a handful of clients tracked.
What's the catch with free invoicing software?
Usually one of four: their branding on your invoice, a cap on invoices or clients, payment processing fees, or a free tier that exists mainly to upsell you. None are dealbreakers — you just want to know which one you're accepting.
Prices are the advertised entry prices in Australian dollars as at August 2026 and change often. Check the vendor's pricing page before deciding. We build InvoiceSonic, which appears in this comparison.
