Best Invoice App Australia (2026): 8 Apps Compared for Small Business

The best invoice app in Australia for most small businesses is InvoiceSonic: it sends and tracks invoices, chases late payers automatically, charges no transaction fee, and lets clients pay by bank transfer or PayID. The best free tool is Invoice-Generator.com.au, which produces an ATO-compliant tax invoice PDF with no signup and nothing stored on a server. We compared eight apps on free plans, GST support, sending and reminders, and one thing most reviews skip: what it actually costs you to get paid.

Quick comparison

"Payment fee" is what you lose when a client pays. Bank transfer and PayID are free wherever supported; card payments are where the money goes. Prices are at the time of writing, AUD unless noted.

1. InvoiceSonic — Best overall

InvoiceSonic is a free invoicing app that creates and sends an invoice from your phone or browser in under a minute, with no signup for the first one. It is built for sole traders and small businesses that want to send the invoice, see when it is paid, and have late payers chased automatically. What sets it apart is the cost of getting paid: 0% InvoiceSonic fee, with clients paying by bank transfer or PayID, so there is no gateway to set up and no card fee eating the invoice.

The Australian tax format is built in alongside NZ, US, UK and Canadian formats across 12 currencies, and it saves your business details and logo so repeat invoices take seconds. The InvoiceSonic invoicing app is on the App Store for iPhone, and a real person (the founder) answers support email.

Pros

• 0% InvoiceSonic transaction fee; clients pay by bank transfer or PayID with no gateway setup.
• Invoice tracker shows who has paid, plus automatic payment reminders and recurring billing.
• No watermark, no signup for the first invoice, Australian GST format included.

Cons

• No in-app card processing, so clients who insist on paying by card or Apple Pay will need another route.
• It is an invoicing app, not accounting software: no payroll, bank feeds or BAS lodgement.
• No dedicated Android app at the time of writing; the browser version works on Android.

Price: Free tier with a Pro upgrade. Best for: Sole traders and small businesses that want digital invoices sent, tracked and chased without paying to get paid.

2. Invoice-Generator.com.au — Best free tool

Invoice-Generator.com.au is a 100% free online invoice generator that turns a form into a downloadable PDF, with no signup, no watermark and no ads. It is for anyone who needs a professional tax invoice now and does not want an account or a subscription to get it. The distinguishing feature is privacy: your invoice data never leaves your browser, so nothing is stored on a server.

The tax invoice generator adds an ABN field, 10% GST and a live ATO-compliance checklist. There are also GST, quote and receipt tools and an invoice template for each trade and profession — plumber, electrician, cleaner, photographer, consultant and more.

Pros

• Completely free with unlimited invoices; no account, watermark or ads.
• Nothing stored on a server — the PDF is generated in your browser.
• Logo upload, auto-calculated totals and an ATO checklist for tax invoices.

Cons

• It generates a PDF only. It does not send the invoice, track payment or send reminders.
• Because nothing is stored, keep your own copy of each invoice.

Price: Free, always. Best for: One-off or occasional invoices where you want a compliant PDF in under a minute and would rather email it yourself.

3. Square Invoices — Best for card payments

Square Invoices is the free invoicing arm of the Square payments platform, and it is the pick if your clients want to pay by card, Apple Pay, Google Pay or Afterpay from the invoice itself. It suits businesses already taking card payments in person with Square. The trade-off: at the time of writing, Square charges 2.2% on online card payments in Australia and 6% + 30c (ex GST) on Afterpay.

Pros

• Free plan sends unlimited invoices, estimates and contracts with no monthly fee.
• Card, Apple Pay, Google Pay and Afterpay built into the "pay now" button.
• iOS and Android mobile app; ties in with Square point of sale.

Cons

• 2.2% on every online card payment: on a $5,000 invoice that is $110.
• Bank transfer and PayID are not in the pay-now flow; you add your BSB in the notes and mark it paid by hand.
• Custom layouts, batch invoices and milestone schedules need Plus ($30/month at the time of writing).

Price: Free; Plus $30/month AUD at the time of writing; 2.2% per online card payment. Best for: Retail, hospitality and service businesses whose clients expect to tap a card.

4. Zoho Invoice — Best feature-rich free plan

Zoho Invoice is free for Australian businesses and is the most complete free plan on this list: quotes, recurring invoices, expense tracking, time tracking, a client portal and automatic payment reminders. The limits are 2 users, 3 projects and 500 invoices per year, and free invoices carry "Powered by Zoho Invoice" branding.

Pros

• Free plan with 500 invoices a year, reminders, recurring billing and time tracking.
• Zoho does not add its own payment fee; you connect a gateway such as Stripe or PayPal and pay that gateway's rate (check the current rate).
• iOS and Android apps, plus a customer portal where clients can view and pay.

Cons

• "Powered by Zoho Invoice" branding on the free plan.
• Capped at 2 users and 3 projects; more than that means moving to Zoho Billing (paid plans available — check current pricing).

Price: Free; gateway card fees apply if you take online payments. Best for: Freelancers and small teams who want a free plan that does more than invoicing.

5. Bookipi — Best phone-first invoice app

Bookipi is a mobile app for invoicing and quoting that started in Australia and is designed to be used from a phone on site. It suits tradies who invoice standing in a driveway. The catch: the free plan allows 3 invoices a month, so anyone invoicing weekly will be on paid Starter.

Pros

• Fast, phone-first flow on iOS and Android with quotes, credit notes and eSignatures.
• Starter plan is cheap for unlimited invoices: US$7.60/month billed annually or US$9.99 month-to-month at the time of writing.

Cons

• Free plan is capped at 3 invoices a month.
• Pricing is in USD, so your AUD cost moves with the exchange rate.
• Card payment fees are not listed on the pricing page — check the current rate.

Price: Free (3 invoices/month); Starter from US$7.60/month; Professional from US$39/month at the time of writing. Best for: Tradies who want to invoice from the ute.

6. Rounded — Best for sole traders who want BAS help

Rounded is Australian-built invoicing and bookkeeping for sole traders and freelancers, and its distinguishing feature is tax: tax estimates, tax-ready reports, and on the Pro plan GST tracking with BAS pre-filling. There is no free plan, but there is a 14-day trial with no credit card required.

Pros

• Invoices, quotes, expenses with receipt capture and time tracking in one app.
• Pro plan tracks GST and pre-fills your BAS; accountant access is included.
• Clients can pay by credit card, Google Pay and Apple Pay; iOS and Android apps.

Cons

• No free plan: Starter is $23.95/month and Pro is $29.95/month at the time of writing.
• Card processing rate is not shown on the pricing page — check the current rate.

Price: Starter $23.95/month, Pro $29.95/month AUD at the time of writing; 14-day free trial. Best for: Sole traders who want their invoicing and tax in one Australian app.

7. Reckon One — Best budget accounting software

Reckon One is Australian cloud accounting software whose Accounting Starter plan sends unlimited invoices, tracks GST and manages BAS for $24/month at the time of writing. It is for the small business that has outgrown an invoice app and wants proper books. Card payments run through Stripe, so the fee is Stripe's rate.

Pros

• Unlimited invoices, GST tracking and BAS on the cheapest plan.
• Reckon Invoice App for iOS and Android is included with every subscription.
• Payroll available as an add-on when you hire.

Cons

• No free plan.
• Stripe card fees apply to online payments — check the current rate.

Price: From $24/month AUD at the time of writing. Best for: Small businesses that need accounting, not just invoices.

8. MYOB — Best for payroll and growing teams

MYOB is one of the two dominant accounting platforms for Australian businesses, and its entry plan, MYOB Solo, is aimed squarely at sole traders with unlimited quotes and invoices. It is the right choice when you are hiring: payroll, superannuation and Single Touch Payroll are what MYOB does that invoice apps do not.

Pros

• Unlimited invoices on the cheapest plan; a clear upgrade path to full payroll and inventory.
• Mobile app for sending invoices and capturing receipts on iOS and Android.
• Heavy introductory discounts: Solo was $12 for the first year at the time of writing.

Cons

• Regular prices are the real cost: Solo $99/year, Lite $315/year, Pro $70/month at the time of writing.
• Online invoice payment fees are not shown on the pricing page — check the current rate.

Price: Solo $99/year regular, Pro $70/month regular AUD at the time of writing; promotional pricing varies. Best for: Businesses with staff or the intention to hire.

What to look for in an invoice app

• Cost of getting paid. A free plan is not free if every payment loses 2.2%. Check whether the app supports bank transfer or PayID with no fee, and what the card rate is if you offer it.
• Australian tax invoice fields. If you are registered for GST, the ATO requires the words "Tax invoice", your identity and ABN, the date, a description of the items, the GST amount, and the buyer's identity or ABN for sales of $1,000 or more. Check the GST shows as a separate line.
• Sending, tracking and reminders. The fastest fix for slow payers is automatic payment reminders; if an app only makes a PDF, you are the reminder system.
• Mobile app that matches your phone. Most apps here run on iOS and Android; InvoiceSonic is iPhone plus browser.
• Limits on the free plan. Bookipi caps at 3 invoices a month, Zoho at 500 a year; InvoiceSonic and Invoice-Generator.com.au do not cap volume.
• Clear payment terms. The app should print a due date, not just "Net 14". Our guide to invoice payment terms in Australia covers which terms get you paid fastest.

When not to use InvoiceSonic or a free generator

If you employ staff, you need payroll, superannuation and Single Touch Payroll reporting, and that means accounting software: MYOB, Xero or Reckon One. If you run a trades business with jobs to schedule, Tradify or ServiceM8 will do the invoicing as a by-product of the job. An invoice app wins on cost and speed for billing; it does not replace your books.

Which one should you choose?

• If you send fewer than 5 invoices a month and just want a PDF → the free Australian invoice generator. No account, ATO checklist, done in a minute.
• If you send invoices weekly and want to stop chasing people → InvoiceSonic. Sends, tracks, reminds, 0% fee, paid by bank transfer or PayID.
• If your clients want to tap a card, Apple Pay or Google Pay → Square Invoices, and budget 2.2% per online card payment into your cash flow.
• If you want a free plan with time tracking and a client portal → Zoho Invoice, accepting the branding and the 500-invoice cap.
• If you want your BAS sorted in the same app → Rounded for sole traders, Reckon One or MYOB once you have staff.

Some invoices still go unpaid whatever you pick. Our guide on how to chase overdue invoices in Australia covers the reminder sequence and the steps after that.
