The best invoicing software in Australia depends on your stage: sole traders want low cost and simple GST handling, while growing service businesses need quoting, jobs and payments in one place.
Yes, there is genuinely free invoicing software in Australia — OneBookPlus has a free plan with proper Australian GST invoicing, while most accounting suites (Xero, MYOB, QuickBooks) are paid-only after any trial.

A compliant Australian tax invoice must show your ABN, the words 'Tax invoice', the GST amount (10%) and, for sales of $1,000 or more, the buyer's identity — any software you pick should produce this automatically.
Tools like Xero, MYOB and QuickBooks are built around full accounting and ledgers; OneBookPlus, Rounded and Hnry focus more tightly on getting invoices out and getting paid.
If you also send quotes, take bookings and run jobs, an all-in-one platform like OneBookPlus removes the need to bolt invoicing onto a separate CRM or job-management app.
Online payments (card and PayTo/bank) on your invoices is the single biggest lever for getting paid faster — prioritise software that has it built in rather than as a costly add-on.
Choosing the best invoicing software in Australia is less about finding the single "best" app and more about matching the right tool to how your business actually runs. A sole-trader designer billing five clients a month has very different needs to a plumbing business sending quotes, booking jobs and chasing payments across a dozen sites every week.
This guide compares seven invoicing apps Australian small businesses actually consider in 2026 — including which ones are free, which handle GST and BAS properly, and which let your customers pay the invoice online. We've kept the facts Australian and current, and flagged where a tool is genuinely strong rather than just popular.
Before the table, it helps to be clear on what good invoicing software needs to do here in Australia specifically:
Produce a valid tax invoice. Under ATO rules, a compliant tax invoice must include your ABN, the words "Tax invoice", the date, a description of what was sold, the GST amount (or a statement that GST is included), and — for sales of $1,000 or more — enough information to identify the buyer. Good software does this for you so you never get a payment held up over formatting.
Handle GST cleanly. If you're registered for GST, every invoice needs the 10% calculated correctly, and your software should make BAS time painless rather than a spreadsheet scramble.
Get you paid. The fastest way to shorten your payment cycle is letting customers pay straight from the invoice by card or bank transfer.
Fit your workflow. If you also quote, take bookings or run jobs, invoicing that lives in the same system as everything else saves hours of double entry.
With that lens, here's how the main options stack up.
Pricing tiers and availability change regularly — always confirm current plans on each provider's site before you commit. The comparison above reflects each product's general positioning in the Australian market.
OneBookPlus is built for Australian service businesses and tradies who want more than just invoicing. The free plan gives you professional, ATO-compliant invoicing with GST calculated automatically, plus quoting and an online booking page — and as you grow, paid tiers add online payments, CRM, jobs and BAS reports in the same platform. That matters because most businesses don't only invoice: they quote first, then do the work, then bill. Running all of that in one place removes the double-handling you get when invoicing sits in one app and your customer list or job schedule sits in another.
If you've ever copied a quote into an invoice by hand, re-typed a customer's details for the third time, or paid for a separate scheduling tool on top of your accounting software, the all-in-one approach is what fixes that. You can start your free trial and have a branded tax invoice out the door in a few minutes.
Xero is the most widely used cloud accounting platform in Australia and the benchmark many businesses compare against. Its invoicing is solid, its BAS and GST reporting are mature, and almost every Australian bookkeeper and accountant knows it. The trade-offs: there's no free plan (only a trial), online card payments require connecting a third-party gateway like Stripe or GoCardless, and it's accounting-first — quoting, bookings and job management generally mean extra add-ons or separate apps. If you want a closer look at how the two compare, see our OneBookPlus vs Xero breakdown.
MYOB is the other long-established Australian accounting name, strong for businesses that need integrated payroll and more traditional bookkeeping. Invoicing and GST are well covered. Like Xero, it's a paid product aimed at the accounting end of the spectrum rather than the lightweight "send an invoice and get paid" use case.
QuickBooks Online is a popular small-business choice that blends invoicing with full accounting, GST tracking and BAS support. For Australian users, online payments aren't handled by a native QuickBooks processor — you accept invoice payments through a connected provider such as PayPal or GoCardless, with the usual transaction fees. It's a capable all-rounder, though again it's accounting-led and paid-only, so you're buying a ledger you may not need if your main goal is simply billing clients.
Rounded is designed specifically for Australian freelancers and sole traders. It keeps things focused: invoices, quotes, expenses and GST tracking without the weight of a full accounting suite. It's a clean option if you're a one-person business and accounting depth isn't a priority. There's no permanent free tier (a trial then paid plans), and it's deliberately narrower than an all-in-one platform.
Hnry takes a different model: you invoice through it, and it automatically calculates and sets aside your income tax and GST, then pays the ATO on your behalf, charging a percentage of the income that flows through. For sole traders who hate tax admin, that's genuinely valuable. The flip side is the percentage-based cost can add up at higher incomes, and you're handing over a lot of control of your tax affairs.
Wave offers genuinely free invoicing and is often mentioned in "free invoicing software" lists, so it's worth knowing where it stands. The catch for Australian users: Wave is a North American product that withdrew from the Australian market and is no longer available to new Australian businesses, so you can't rely on it for local GST or BAS support. If you specifically want simple free invoicing in Australia, a locally built free plan is the safer path.
Yes. This is one of the most common questions, so to be clear: you do not have to pay to send a professional invoice in Australia.
OneBookPlus has a free plan that includes proper Australian invoicing with GST. By contrast, the big accounting suites — Xero, MYOB and QuickBooks — generally only offer a free trial, then move to paid monthly plans. Wave is free but no longer serves Australian users, so it isn't a current option for local GST invoicing.
If you just want to create one invoice right now without signing up for anything, you can also use a free invoice generator to produce a compliant invoice in your browser as a try-before-you-commit option. When you're ready to track who's paid, send reminders and keep a customer history, that's when moving to proper online invoicing software pays off.
You're a sole trader who hates tax admin: Hnry (tax handled for you) or OneBookPlus's free plan (keep control, pay nothing to start).
You're a freelancer or consultant who wants clean invoicing: Rounded or OneBookPlus.
You run a service business or trade with quotes, bookings and jobs: OneBookPlus, because invoicing, quoting, online booking and your CRM all live together. For trade-specific picks, see our guide to the best invoicing software for tradies.
You need deep accounting or payroll and have a bookkeeper: Xero, MYOB or QuickBooks.
You want the absolute simplest free tool to start with: OneBookPlus's free plan, which is built for Australian GST from day one.
Whatever you choose, if you're registered for GST your software should calculate the 10% automatically and make lodging your BAS straightforward. It should also reliably produce a valid tax invoice every time — getting the format wrong is a common reason invoices get queried or paid late. If GST is new to you, our Australian GST Calculator guide walks through adding and removing the 10%.
The biggest practical difference between tools is whether customers can pay the invoice online. Built-in card and bank payments consistently shorten payment times compared to "please transfer to this BSB". When you compare apps, check whether payments are native or a clunky third-party add-on.
There's no universal "best invoicing software in Australia" — but there is a best fit for you:
For all-in-one service businesses and tradies who quote, book and bill, OneBookPlus brings it together on a free-to-start plan.
For full accounting and payroll, Xero, MYOB and QuickBooks remain the heavyweights.
For sole traders, Rounded and Hnry are focused, well-built Australian-friendly options.
If your goal is to send clean, GST-correct invoices, get paid faster, and stop juggling separate apps for quotes, bookings and customers, OneBookPlus is the most complete starting point — and you can sign up for free and send your first invoice today.
