Key takeaways:

• The best small business invoice software in Australia includes Airwallex, Xero, and MYOB.

Cash flow is the pulse of any small business, yet for many Australian business owners, growth remains difficult. While profits for businesses have been shown to be improving, buoyed by initiatives like cost-cutting and improving productivity through AI, there has also been an uptick in company insolvencies¹. 

Getting on top of your finances and setting up the right infrastructure for growth has never been more important, and part of this is having the right business invoice software in place. Let’s take a look at some of the best invoice software available to Australian business owners so you can pick the right one for your business.

What is small business invoice software?

Modern invoicing software has evolved far beyond the simple generation of a PDF document. Today, these platforms act as a central nervous system for your business's accounts receivable. They handle end-to-end automation, from the initial quote to automated payment reminders and final reconciliation with your bank feeds. By integrating payment tools directly into the invoice, you allow customers to pay via a single click, skipping the slow, traditional manual transfer process and getting your money where it belongs: in your business.

Compare the top small business invoice software

Choosing the right platform depends on your business's scale, and whether you operate purely within Australia or have a global footprint. Below is a comparison of the top contenders in the Australian market for 2026.

In-depth: Features of the best invoice software

Airwallex

Airwallex is a global financial platform designed to strip the complexity and high costs out of international business. For Australian businesses that look beyond domestic borders, Airwallex provides a comprehensive billing hub that manages everything from one-off project fees to complex recurring subscriptions.

• Get paid faster with local and global payments: You can send professional invoices that include a "Pay now" link. This allows your customers to pay in AUD or their preferred foreign currency using credit cards or over 160 local payment methods.

• One-off and recurring billing: Manage all your revenue streams from a single hub. Whether you are billing for a one-time setup fee or managing monthly retainers, Airwallex allows you to automate the entire lifecycle.

• Automatic payment collection: You can choose to auto-charge saved cards on the due date or send digital links for manual payment. If a payment fails, the platform uses smart retries and dunning processes to recover funds without you having to lift a finger.

• Built for the global economy: Unlike traditional platforms that force currency conversions at high mark-ups, Airwallex lets you set prices in multiple currencies and settle "like-for-like" into your multi-currency wallet. You can then use those funds to pay global suppliers directly, avoiding unnecessary FX fees entirely.

Fees: You can access Airwallex Billing, including all other features such as Global Accounts, Payments, FX and more, for A$99/month. 

Pros: Unrivalled global reach, 160+ local payment methods, multi-currency capabilities, interbank FX rates, and seamless sync with Xero and QuickBooks. 

Cons: It is not a standalone accounting suite, meaning you will still need a tool like Xero for your BAS and tax lodgements.

Xero

As a staple of the Australian accounting landscape, Xero is known for its user-friendly interface and ecosystem of integrations.

• Professional online invoices: Create branded templates and include "Pay now" buttons that integrate with Stripe or GoCardless.

• eInvoicing: Xero supports the Peppol network, allowing you to send and receive eInvoices directly between different accounting systems for faster, more accurate processing.

• Mobile flexibility: The Xero mobile app allows you to create, send, and track the status of invoices while you are on the move.

Fees:  Pricing tiers for small businesses start at A$75 per month. Sole traders can access Xero from A$35 per month.

Pros: Ecosystem of over 1,000 apps, local support, real-time reporting, cash flow forecasting, and ATO readiness. 

Cons: Pricing increases in recent years; multi-currency is only available on higher tiers; and payroll is quite limited until you reach higher tiers.

MYOB

MYOB is widely used in the Australian market with a deep understanding of local regulatory requirements.

• ATO-ready: Integration with Australian Tax Office systems, ensuring your GST and STP obligations are met with minimal fuss.

• Online payment variety: Customers can pay via card, PayPal, BPAY, Apple Pay, or Google Pay. These payments are automatically matched in your ledger, simplifying reconciliation.

• AI-powered reminders: MYOB uses Smart Invoice reminders to nudge overdue customers, helping to keep your cash flow steady.

Fees: Starts at approximately A$30 per month for a Pro account. 

Pros: Powerful reporting and robust local compliance features with business insights, unlimited invoices, and 24/7 chat support. 

Cons: The user experience (UX) can sometimes feel less modern than newer, cloud-first fintech platforms, and multi-currency is only available with the highest tier plan.

QuickBooks Online

QuickBooks is a global competitor that offers a highly intuitive mobile experience, making it a choice for tradespeople and service providers who are rarely at a desk.

• Automated workflows: QuickBooks can automate repetitive tasks, such as recurring invoices and expense tracking.

• Real-time insights: The dashboard provides a clear view of your profit and loss, helping you make data-driven decisions on the fly.

Pros: Highly customisable mobile app, budgeting tools, unlimited invoices. 

Cons: There can be a steep learning curve for new users, backup and data restore only available on the highest tier plan, business intelligence features mainly limited to higher tier plans.

Zoho Invoice

For those just starting out, Zoho Invoice offers a powerful entry point with a generous free tier.

• Client portal: Zoho provides a dedicated portal where your customers can view their payment history and pay outstanding bills.

• Time tracking: It includes built-in tools to track time on projects, which can be automatically converted into invoices.

Pros: Excellent value for money and strong automation for a free product. 

Cons: The interface is less "Australian-centric" than Xero or MYOB, requiring more manual setup for local tax nuances.

Features to look for in invoice software

When evaluating which platform will serve your business best into 2026, consider these four pillars:

ATO Compliance 

Ensure the software handles Single Touch Payroll Phase 2 and GST calculations accurately to avoid headaches during BAS time.

Automated reminders

Your software should let you seamlessly follow up on late payments. Automated nudges for overdue invoices can reduce your Days Sales Outstanding (DSO) without damaging customer relationships.

Multi-currency support 

If you have any intention of selling services or products overseas, look for a platform that allows you to bill and settle in multiple currencies to avoid losing 3–4% on every transaction to FX mark-ups.

Mobile app quality

As a business owner, you shouldn't be tied to a desktop. The ability to send an invoice the moment a job is finished – right from your phone – is a proven way to get paid faster.

Frequently asked questions

What is the best free invoicing software in Australia? 

For micro-businesses and sole traders, Zoho Invoice remains a popular free option. For businesses that need to scale or handle international payments, Airwallex offers a powerful choice for businesses that provides much more room for growth.

Can I use international invoice software in Australia? 

Yes, but you must ensure it is configured for Australian GST and can integrate with systems that handle STP 2 if you have employees. Many international platforms lack these specific local requirements, which is why choosing a platform with strong Australian integrations is vital.

How do I get paid faster by clients? 

The two most effective ways to speed up payment are providing a "Pay now" link directly on the invoice and setting up automated reminders. By removing the friction of manual bank transfers and ensuring your invoice stays at the top of their inbox, you significantly increase the likelihood of being paid on time.
