6 Best Invoice Apps for Small Businesses in Australia (2026 Update)

If customers pay late, it’s often because the invoice went out late, was hard to pay, or nobody followed it up. The right invoice app fixes most of that. It lets you send a proper tax invoice in a couple of minutes, takes card payments, and sends the reminder so you don’t have to.

We’ve updated this list for 2026. Prices come from each vendor’s Australian website, checked 14 November 2026. If you’d like a hand picking one or setting it up, that’s something we help with as part of our bookkeeping services in Brisbane and our Xero and MYOB setup service.

What to look for

Start with the basics. The app has to produce a valid Australian tax invoice with your ABN and GST shown correctly. Online payment is next, because customers pay faster when there’s a button to click. Check the card fees while you’re at it.

Automatic reminders are worth more than people expect. So is a link to your accounting software, since invoices that flow straight into your books make the bank reconciliation and BAS much quicker. And if you plan to take on staff, think about whether the app can grow into payroll and Single Touch Payroll, so you don’t have to switch later.

The 6 best invoice apps for Australian small businesses in 2026

1. Square Invoices

Square is hard to beat if you mostly need to send invoices and get paid by card. The free plan gives you unlimited invoices, estimates and contracts, plus recurring invoices, deposits and automatic payment reminders.

• Price (checked 14 November 2026): Free plan $0 a month. Plus plan $30 a month, with a 30-day free trial. Card processing is 2.2% for online card payments and 1.6% in person (for sellers who signed up on or after 30 May 2024). Source: Square Invoices pricing.
• Good for: sole traders and service businesses who want free invoicing and quick card payments.
• Keep in mind: it’s an invoicing and payments tool, not accounting software. You’ll still need something else for BAS and payroll.

2. Zoho Invoice

Zoho Invoice is free for Australian businesses. You can send tax invoices and quotes, set up recurring invoices and reminders, record expenses and give customers their own portal.

• Price (checked 14 November 2026): free. Zoho lists limits of two users, three projects and 500 invoices a year, and invoices carry “Powered by Zoho Invoice” branding. Source: Zoho Invoice pricing (AU).
• Good for: very small businesses that want a free, tidy-looking invoice.
• Keep in mind: Zoho says data may be deleted if an account is inactive for more than 180 days, so keep a backup.

3. Xero

Xero is full accounting software, so invoicing is only one part of it. Every plan on Xero’s Australian pricing page includes invoices and quotes, online invoice payments, bank reconciliation, GST and BAS lodgement, automated super and payroll.

• Price (checked 14 November 2026): Comprehensive $107 a month, Ultimate 10 $143, Ultimate 20 $180 and Ultimate 50 $250 (AUD, including GST). New customers can get an introductory discount, and payment fees apply to online invoice payments. Source: Xero pricing plans.
• Good for: growing businesses that want invoicing, bookkeeping, BAS and payroll in one place.
• Keep in mind: it costs more than a stand-alone invoice app, and it’s worth setting up properly from day one. Two of our team are Xero certified advisors, and we can supply your Xero subscription and bill it monthly with our services. See Xero bookkeeping.

4. MYOB Business (Lite and Pro)

MYOB is Australian accounting software with unlimited quotes and invoices, online payments, GST and BAS lodgement, and payroll with Single Touch Payroll as an add-on.

• Price (checked 14 November 2026): Lite $315 a year after the offer period (for sole traders and small businesses with up to 2 employees). Pro $70 a month after the offer period. AccountRight Plus $165 a month after the offer period. Payroll on Lite and Pro is an extra $5 a month per employee. Source: MYOB pricing.
• Good for: businesses that want invoicing, BAS and payroll from an Australian provider.
• Keep in mind: features like unlimited bank accounts and timesheets depend on the plan, so compare before you sign up. We work with MYOB for our clients. See MYOB bookkeeping.

5. Solo by MYOB

Solo is MYOB’s phone app for sole traders. It handles unlimited quotes and invoices, tracks GST and takes in-person payments with Tap to Pay.

• Price (checked 14 November 2026): $99 a year after the offer period. MYOB was advertising $12 for the first 12 months. Source: MYOB pricing.
• Good for: sole traders who run everything from their phone.
• Keep in mind: MYOB says Solo tracks GST only (BAS lodgement starts at Lite), it’s one user, and you can’t change plans later.

6. QuickBooks Online

QuickBooks Online is full cloud accounting software. Every plan on its Australian pricing page includes invoicing and payments, bank feeds and GST tracking with BAS e-lodgement. Recurring invoices start on the Essentials plan.

• Price: QuickBooks offers Simple Start, Essentials, Plus and Advanced plans with a 30-day free trial. Check QuickBooks AU pricing for current monthly prices and offers.
• Good for: businesses that want full accounting with a range of plan sizes.
• Keep in mind: user numbers depend on the plan, from 1 user on Simple Start to 25 on Advanced. We work with QuickBooks Online for our clients. See QuickBooks bookkeeping.

These are the regular prices after any introductory offer, and vendors change them from time to time. Check the vendor’s site before you buy.

Free invoice app or full accounting software?

When you’re just starting out, a free invoice app is often plenty. Once you register for GST, put on staff or want regular reports, full accounting software usually saves time, because invoices, bank transactions, GST, payroll and BAS all sit in the one system. For employers, Payday Super, which started on 1 July 2026, makes that even more worthwhile. Our post on why Xero matters for compliance in 2026 explains why.
