Cash flow is the pulse of any small business, yet for many Australian business owners, growth remains difficult. A report by the Australian Chamber of Commerce and Industry found that cash flow pressure was named as a source of stress for 41% of Australian small business owners¹.

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?

Small business invoice software are digital platforms that streamline how you bill customers and suppliers, and how you get paid. 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. Invoice software platforms such as Airwallex offer features that include invoice generation, automated accounts payable, payment integration with local payment methods, multi-currency support, expense management and financial reporting, purchase orders, multi-layer approval flows, and more.

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: 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, across 130+ currencies and 180+ countries.

• One-off, recurring, and usage-based billing: Manage all your revenue streams from a single hub. Whether you're billing for a one-time setup fee, monthly retainers, or metered usage, Airwallex automates the entire lifecycle — and supports multi-entity billing if you operate more than one legal entity.

• Automatic payment collection: 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.

• Deep accounting integrations: Two-way sync with Xero, and QuickBooks keeps your billing data flowing straight into your books for easy reconciliation. Netsuite integration available on the Accellerate plan.

Fees: You can access Airwallex Billing, including all other features such as Global Accounts, Payments, FX and more, for A$99/month. Note: Subscription Management and Usage-based Billing carry an additional 0.50% fee per successful transaction.

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.

Why businesses choose Airwallex for invoice payments

Airwallex is built for modern businesses operating globally. We combine professional invoicing with the multi-currency infrastructure, automation, and accounting integrations you need to get paid faster – wherever your customers are.

Invoices in minutes, no coding required

Create and send professional invoices directly from the Airwallex WebApp in minutes. Every invoice can include a "Pay now" link for instant online payment, and supports both one-time billing – project work, setup fees, retainers – and recurring subscriptions from a single hub. You can even draft invoices from purchase orders using plain-English AI prompts.

Local and global payment methods

Customers pay in their preferred method and currency, with support for 160+ local payment methods and invoicing available in 130+ currencies. You settle like-for-like into your multi-currency wallet in 20+ currencies — no forced FX conversions.

Real-time tracking, reconciliation, and automated follow-up

Invoice statuses update in real time – issued, pending, overdue, paid – and reconcile automatically against payments once confirmed. If an invoice goes unpaid, automated reminders and dunning (with up to four retries) chase it down without any manual follow-up.

Subscription management

Airwallex Billing runs the full recurring billing lifecycle on autopilot – plans, trials, upgrades, and renewals – so you're not manually managing every cycle.

Multi-currency settlement and funds management

Payments settle like-for-like in the invoice currency, avoiding unnecessary FX costs. Those funds can then cover card spend, bill payments, reimbursements, and expenses from the same account.

Automated global sales tax and accounting integrations

Airwallex Billing can help apply sales tax calculations for supported jurisdictions, helping Australian businesses invoicing internationally manage their compliance obligations.. Deep integrations with Xero and NetSuite sync bank and payment feeds automatically, so invoices carry an Airwallex "Pay now" button and reconciliation happens without manual month-end work.

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.
