Best Invoicing Software Australia (2026): Top 9 Compared

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 nine 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. Every price below is checked against the provider's own published pricing page. We've kept the facts Australian and current, and flagged where a tool is genuinely strong rather than just popular.

What "best" actually means for an Australian business#

Before the table, it helps to be clear on what a good invoicing app 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 nine main options stack up.

The top 9 compared (2026)#

Prices checked against each provider's published pricing page in July 2026. FreshBooks bills in US dollars, so Australian-dollar figures are approximate and move with the exchange rate. Plans and tiers change: always confirm current pricing on the linked pages before you commit.

1OneBookPlus: best all-in-one for service businesses#

Pricing: free plan, then $29 (Starter), $49 (Plus) and $69 (Growth) per month, GST inclusive, with a discount on annual billing. Full details on the OneBookPlus pricing page.

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. The OneBookPlus invoicing features page walks through the full module, from branded GST invoices to payment tracking.

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.

2Xero: the established accounting standard#

Pricing: Ignite $35/month, Grow $75, Comprehensive $100 and Ultimate $130 (AUD, per the Xero Australia pricing page, checked July 2026). Trial only, no free plan.

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), the entry Ignite plan caps invoices at 20 a month, 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.

3MYOB: accounting with payroll depth#

Pricing: Solo $12/month, Lite $30 and Pro $63, with AccountRight tiers above that (AUD, per the MYOB pricing page, checked July 2026). Trial only, no free plan.

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, and the Solo plan is one of the cheapest paid entry points on this list. Like Xero, it's aimed at the accounting end of the spectrum rather than the lightweight "send an invoice and get paid" use case. Our OneBookPlus vs MYOB comparison covers the differences in detail.

4QuickBooks: invoicing plus accounting for small business#

Pricing: Simple Start $25/month, Essentials $45, Plus $75 and Advanced $95 (AUD, per the QuickBooks Australia pricing page, checked July 2026). Trial only.

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. See our OneBookPlus vs QuickBooks comparison for a side-by-side.

5Zoho Invoice: free invoicing from a big ecosystem#

Pricing: free. Zoho Invoice is a no-cost product funded by Zoho's wider paid suite, with usage caps at scale.

Zoho Invoice is the standout freebie on this list: professional invoices, quotes, payment reminders and time tracking at no cost, with an Australian edition that puts GST on your invoices. The catches are what sits around it. It's invoicing only, so there's no BAS reporting or ledger (Zoho steers you toward the paid Zoho Books for that), it's one door into a 50-plus product ecosystem that assumes you'll grow into more Zoho subscriptions, and support for a free product is naturally thinner. It's a strong pick for a sole trader who wants free and polished; to see how the broader platforms compare, read our OneBookPlus vs Zoho comparison.

6FreshBooks: polished billing, priced in US dollars#

Pricing: Lite about US$24/month (roughly A$36) for up to 5 billable clients, Plus about US$44 (roughly A$66) for 50 clients, and Premium about US$66 (roughly A$99) for unlimited clients (per the FreshBooks pricing page, checked July 2026; billed in USD).

FreshBooks is a Canadian-built invoicing and light-accounting tool with a genuinely pleasant interface and good time tracking for freelancers. For Australians the friction is structural: you're billed in US dollars (so your software cost moves with the exchange rate), the Lite plan's five-client cap is tight, and tax handling is a generic sales-tax setup rather than a native Australian GST and BAS workflow. Our OneBookPlus vs FreshBooks comparison goes deeper on the differences.

7Wave: free, but no longer available in Australia#

Pricing: free Starter plan with a paid Pro tier (USD, per the Wave pricing page), but not open to new Australian businesses.

Wave offers genuinely free invoicing and is often mentioned in "free invoicing" 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. Our OneBookPlus vs Wave comparison covers what Australians lose by choosing it.

8MeMate: Australian-built business management#

Pricing: Business $99.85/month and Business+Work $162.17/month, with custom Enterprise pricing (per the MeMate pricing page, verified July 2026). No free plan.

MeMate is an Australian-built business management platform that wraps quoting, invoicing, job and project tracking, and customer management into one system, closer in shape to OneBookPlus than to the accounting suites. It's pitched at established teams running project-based work rather than sole traders sending a handful of invoices each month, and the entry price reflects that: at nearly $100 a month it's the most expensive starting point on this list. If you're weighing the two all-in-ones, our OneBookPlus vs MeMate comparison has a sourced row-by-row breakdown.

9ServiceM8: job management for trades, invoicing included#

Pricing: free up to 30 jobs/month, then Starter $29 (50 jobs), Growing $79 (150 jobs), Premium $149 (500 jobs) and Premium Plus $349 (AUD, GST inclusive, per the ServiceM8 pricing page, checked July 2026). Billed by jobs created, not per user.

ServiceM8 is trade job management first and invoicing second: jobs, scheduling, on-site quoting and invoicing from a job card, with the bookkeeping handled by syncing to Xero, MYOB or QuickBooks rather than a built-in ledger. The per-job pricing suits bigger crews doing fewer, larger jobs, but high volumes of small callouts push you up the tiers quickly, and you'll still pay for an accounting subscription on top. Compare the two approaches in our OneBookPlus vs ServiceM8 breakdown, and for the wider trade field see our guide to the best invoicing software for tradies.

Booking and invoicing software in one place#

A lot of readers arrive here looking for booking and invoicing software together rather than a standalone billing tool, and that combination deserves its own section. If your work is booked in (trades, cleaners, salons, allied health, lessons, repairs), the booking and the bill are two halves of the same job. Keeping them in separate apps is exactly where double entry, missed charges and "did we ever invoice that one?" creep in.

Of the nine tools above, only two treat bookings as a first-class feature. OneBookPlus is built so that invoicing, quoting, online booking and your CRM all live together: a booking becomes a job, and the job becomes the invoice, without re-typing anything. ServiceM8 schedules trade jobs well but leans on an external accounting app for the books. The accounting suites (Xero, MYOB, QuickBooks) leave bookings to third-party add-ons entirely. If bookings drive your week, start from a platform where they're native, and read our online booking system guide for how to set up the booking side well.

Is there free invoicing software in Australia?#

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, and Zoho Invoice is free as well (invoicing only, with no BAS reporting). 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.

How to choose the right invoicing app for you#

Use these quick rules of thumb:

• You're a sole trader watching every dollar: OneBookPlus's free plan or Zoho Invoice. Both are free; only OneBookPlus adds BAS-ready reporting and payments as you grow.
• You're a freelancer or consultant who wants clean billing: FreshBooks (if USD billing doesn't bother you) 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 run an established project-based team: MeMate, or OneBookPlus's Growth plan at a fraction of the price.
• You want the absolute simplest free start: OneBookPlus's free plan, which is built for Australian GST from day one.

Don't forget GST and BAS#

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%.

Prioritise getting paid#

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.

The bottom line#

There's no universal winner, 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 free invoicing, OneBookPlus's free plan and Zoho Invoice are the two real options for Australians today.
• For trade job management or project-heavy teams, ServiceM8 and MeMate are credible specialists, at specialist prices.

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. You can sign up for free and send your first invoice today, and when you're curious about cost as you grow, the OneBookPlus pricing page shows every tier with GST included.

Send a compliant invoice in minutes, get paid online, and keep your quoting, bookings and customers in one place, without paying for software you don't use yet.
