Best Invoicing Software for Australian Businesses in 2025
For many Australian businesses, invoicing is still a time-consuming, manual task – even in 2025.
Whether it’s creating Word or Excel templates, chasing late payments, or staying on top of GST and BAS obligations, invoicing can quickly turn into a mess of paperwork and frustration.
But the right invoicing software doesn’t just make it easier to send professional invoices. It helps you get paid faster, improves your cash flow, reduces errors, and saves you hours each week. It also gives your customers more convenient ways to pay and makes your business look more polished and trustworthy.
This guide compares some of the top invoicing software options for Australian small businesses, freelancers, sole traders and tradies, with a close look at how Zeller stacks up as an all-in-one solution.

Why your Australian business needs invoicing software.
Whether you’re a plumber, graphic designer, or running a café, invoicing is at the heart of your business operations. Invoicing isn’t just a box to tick, it's one of the most important touchpoints between you and your customers.
Here’s why switching to proper invoicing software is a smart move:
Get paid faster: Offer an instant, secure payment option and reduce the back-and-forth
Easier for your customers: Save your customers from having to manually transfer funds
Look more professional: Send polished, branded invoices in a few clicks
Save time: Automate invoice payment reminders, recurring invoices, and more
Stay compliant: Automatically handle GST to help you prepare for BAS
Track everything: See who’s paid, who hasn’t, and what’s overdue
Work on the go: Create and send invoices from your phone or tablet
By choosing the right invoicing tool, you'll be giving your cash flow a boost and freeing yourself to focus on growing your business.
How to choose the best invoicing software for your Australian business.
Not all invoicing tools are made the same. Some are built into broader accounting platforms while others are standalone tools. If you’re shopping around, here are the key features and criteria to consider:
Ease of use and interface
A clean, intuitive interface on your invoice app is essential, especially if you’re not naturally a numbers person. Look for software that’s genuinely easy to use, whether you’re sending invoices from your desktop, or directly from your smartphone when you’re on the go.
Invoicing features
Naturally, you want flexibility and control. Does the software let you invoice on the go? Can you add your logo and colours to your invoices? Apply discounts or GST line items? Track invoice status? Set up recurring or scheduled invoices? Zeller Invoices does all that and more.
Payment acceptance and speed
Getting paid quickly matters. Does the software support secure credit card payments? Can customers pay instantly via a secure link? Just as importantly, how quickly do those funds land in your account – within a few business days, or by the next day? With Zeller Invoices, funds settle nightly into your Zeller Business Transaction account. So when your customers pay, you’ll have your funds by the next morning.
Integration and ecosystem
Good invoicing software should integrate with your other tools, especially accounting software like Xero. But beyond that, some solutions (like Zeller Invoices) are part of a bigger ecosystem of financial tools that include EFTPOS terminals, transaction accounts, debit cards, reporting, and more. This integrated ecosystem approach can save you time and reduce complexity.
Pricing model and value
Many platforms advertise a free plan, but keep their features locked behind a paywall. Consider how pricing scales as your business grows, and make sure you’re not paying monthly fees for features you don’t need. Zeller Invoices has no monthly fees, and it’s free to create and send an unlimited number of invoices at no cost to your business.
AU tax compliance
Running a business in Australia with an annual turnover above $75,000 means GST obligations and BAS reporting. Your invoicing software should make that easier, not harder. Choose a tool (like Zeller) that lets you toggle GST and export records for BAS.
Support and local relevance
Does the provider offer local support in Australian time zones? Are help documents written with Australian businesses in mind? Are fees listed in AUD? Local understanding can make a big difference. Zeller’s support team is here to support you 24/7 via phone, email, or SMS.
Top invoicing software options in Australia (and how Zeller Invoices compares).
There’s no shortage of invoicing software out there, but not all are created equal. Here’s a breakdown of some of the top platforms used by Australian businesses.
Zeller Invoices
Zeller Invoices is built specifically for Australian small businesses. You can create and send unlimited invoices for free, and accept online payments via Zeller’s secure payment gateway. Funds settle nightly into a free Zeller Transaction Account. It also lets you:
– Customise invoices with your logo, colours and branding
– Send invoices via email or SMS
– Track payment status in real time
– Automate reminders for late payments
– Create and send invoices from your phone
– Accept payments online with just a tap from your customer
All this without paying any monthly subscription fees, or locking key features behind a paywall.
Square Invoices
Square’s invoicing tools are tightly integrated with its POS ecosystem. It offers a decent free tier, though many features require paid upgrades. Payments take 1 to 2 business days to settle, and the interface leans retail-first.
Xero Invoicing
Xero is first and foremost accounting software, but it includes invoicing features as part of its paid plans. It’s strong on reporting and BAS prep, but you’ll need to pay $32+ per month. That’s not ideal if invoicing is all you need, or if you’re just looking to get started with your first online invoicing tool or mobile invoicing app.
Invoice2go
Invoice2go focuses on mobile-friendly invoicing, particularly for tradies and on-the-go professionals. It offers solid features but quickly gets expensive, with plans starting at $12.99/month and limits on clients and invoices.
MYOB and QuickBooks
These are traditional accounting platforms with invoicing bolted on. MYOB has decent features, but its UI can feel clunky. QuickBooks is more modern, but comes with monthly fees and isn’t built for mobile-first use.
The ability to add pre-populated items to Zeller Invoices makes it a lot faster to create and send, and triggering reminders to customers to prompt them for payment has streamlined my entire invoicing process. I’m no longer wasting hours issuing and chasing late payments — it’s literally saving me hours every week.

Why Zeller Invoices really stands out.
Zeller Invoices is built for the way modern Australian businesses actually work. Mobile-first, tax-compliant, and designed to help you get paid fast. Here’s what sets it apart.
It’s free to create and send invoices
There are no monthly fees, no invoice send limits, and no hidden costs. You only pay a small fee of 1.7% +25¢ for domestic cards (separate pricing for international cards) when a customer pays using their card. That’s it. No surprises.
It’s made for mobile
With Zeller App, you can create, send and manage invoices on the go, in under 30 seconds. Send invoices by email or SMS, track them in real time, and manage everything from your phone. You don’t need to be in the office to run your business.

Easy for your customers
Your customers can pay securely online via card or mobile wallet, straight from the invoice. No app or login required. In fact, over 75% of Zeller Invoices are paid in under 24 hours.
Integrated with the full Zeller ecosystem

Over 75% of Zeller Invoices are paid in under 24 hours.
