Best Invoicing Software for Allied Health in Australia (2026): 8 Tools Compared

The best invoicing software for allied health Australia-wide in 2026 is InvoiceSonic, the only tool here that ships a dedicated NDIS invoice template beside an ordinary Australian tax invoice. If you bill private clients only and send a handful of invoices a month, the free tax invoice generator on this site builds the PDF in your browser with no signup. If you need an appointment book and clinical notes too, buy a practice management system instead. We put all eight through one test: can it invoice a private client, an NDIS participant and a plan-managed or DVA client in the same week?

Quick comparison

"Not listed" means exactly that: the tool's Australian pricing or feature page did not state it at the time of writing, so we have not marked it a yes. Confirm anything you are buying for on a trial first.

How we tested: the mixed-funding test. Three questions. Can it produce three differently shaped invoices in one week, for a private client, an NDIS participant and a plan-managed or DVA client, without rebuilding the template? Can you set the tax treatment invoice by invoice, so one carries a GST line and the next none? And will it send to, and chase, a payer who is not the person you treated?

Allied health is the only field on this site where one clinician sends three shapes of invoice in a week. A private client gets an ordinary tax invoice; an NDIS participant's needs their name and NDIS number, the support item number from the NDIS Price Guide or Support Catalogue, the service dates, the hours and your ABN. A plan manager or a department such as DVA wants it addressed to them, not to the person you treated.

The worked number. Take a A$193.99 consult. If that service is taxable, the GST inside it is one eleventh, or A$17.64. If it is GST-free, the line is A$0.00. Most NDIS supports are GST-free where they are a reasonable and necessary support in a participant's plan, so a clinician billing 20 of those a month with a 10% line on by default is out by A$352.80 a month: A$1,058.40 a quarter, A$4,233.60 a year, in the wrong box at BAS time. Whether a given service is taxable or GST-free depends on the service and the funding source, so confirm your position with the ATO or your accountant before setting a default rate; our GST calculator does the arithmetic.

Who fails the test. Only InvoiceSonic publishes a dedicated NDIS invoice template, so it is the only one of the eight that arrives shaped for a mixed caseload. A free PDF generator, ours included, passes the first question and fails the third: it builds any invoice you can type and sends none. The other six all send properly and all let you address an invoice to somebody other than the client, but none stated an NDIS layout on the pages we checked.

1. InvoiceSonic — Best overall

InvoiceSonic builds a professional tax invoice in about a minute and publishes a dedicated NDIS invoice template beside its ABN and sole trader templates. For a physio, OT, speech pathologist or exercise physiologist with a mixed book, that is the difference between one tool and two.

It is the strongest of the eight on the mixed-funding test. The NDIS layout takes the participant's name, NDIS number, support item number, service dates and hours without a rebuild, and the standard tax invoice handles the private side with an ABN field, a 10% GST label and BSB formatting. You address the invoice yourself, so a plan manager or other third-party payer can be the recipient. Pro adds recurring invoices, automatic reminders and open tracking, which tells you whether a quiet plan manager has looked at it. Payment is by bank transfer or PayID with no InvoiceSonic transaction fee, so a A$193.99 consult arrives as A$193.99.

Pros

• A dedicated NDIS invoice template alongside standard ABN and sole trader tax invoice templates.
• Recurring invoices and automatic reminders on Pro, which suits a client booked into a weekly block.
• Bank transfer and PayID with no InvoiceSonic transaction fee, so nothing is shaved off a A$193.99 consult.

Cons

• Not accounting software: no bank feeds, BAS lodgement or payroll, so a growing practice keeps its books elsewhere.
• Free stops at 3 saved invoices, 1 tracked send and 1 reminder a month; the 7-day Pro trial needs a card; and there is no native Android app.

Price: at the time of writing, the free plan is A$0 and the first invoice needs no sign-up and no card; Pro is A$19 a month billed monthly, or A$168 a year billed annually, which is A$14 a month and saves A$60. Best for: solo and small practices billing private, NDIS and third-party payers from one place.

2. Invoice-Generator.com.au — Best free tool

Invoice-Generator.com.au is a free tax invoice generator that produces a finished PDF in your browser with no signup, no watermark, no ads and no invoice limit. Your invoice data never leaves the browser, which matters when an invoice line describes somebody's treatment.

The Australian tax invoice generator is pre-set with an ABN field, a 10% GST line and a live compliance checklist that flags a missing ABN before you send. Participant details and support item numbers go in the description lines, so the layout is whatever you type. It passes the first question of the mixed-funding test and fails the third completely: it builds the document and never sends it. There are free tools for a quote and a receipt, and a guide to writing an invoice.

Pros

• Free forever, no signup, no watermark and no invoice limit.
• Invoice data never leaves the browser, so participant details sit on no one's server.

Cons

• No sending, tracking or automatic reminders, so chasing a plan manager is a manual job every time.
• No saved client list or payment collection, so a repeat plan-managed client is re-entered each time.

Price: free, always. Best for: clinicians under the GST threshold and anyone who needs one properly formatted invoice today.

3. Zoho Invoice — Best free app that sends and stores payers

Zoho Invoice is free, with Zoho stating no cost and no contracts, and unlike a PDF generator it sends the invoice, saves the payer and keeps the history. Plan managers repeat far more often than individual clients, so the saved-payer list earns its keep.

It passes the sending question and formats an Australian invoice properly. There is no NDIS layout we could confirm, so the participant number, support item number and hours are fields you set up once and reuse. The trade-off is the surroundings: a very large product suite behind it, a dense interface, and support aimed at paid-suite customers.

Pros

• Genuinely free with no contract, and it sends and stores rather than only building a PDF.
• Invoicing in 19-plus languages, useful with clients who prefer another language.

Cons

• Dense interface, and it is the entry point to a large upsell suite.
• No NDIS layout, so every mixed-funding invoice is one you design yourself.

Price: free at the time of writing. Best for: clinicians wanting sending, tracking and a saved payer list for A$0.

4. Square Invoices — Best if private clients pay by card

Square Invoices gives you unlimited free invoices, estimates and automatic reminders, and the client pays by tapping a card link in the email. On a private caseload that settles on the day, that speed is real cash flow.

It half-passes. Reminders sit on the free plan and it sends properly, but there is no NDIS layout and the card fee is the true cost. At 2.2% on online card payments, collecting a A$193.99 consult costs A$4.27. Twenty a month is A$85.36, or A$1,024.27 a year, six times InvoiceSonic Pro billed annually at A$168.

Pros

• Unlimited free invoices with automatic reminders on the free plan.
• Clients pay by card from the invoice itself, so private fees often land the same day.

Cons

• 2.2% on card payments is A$1,024.27 a year on 20 consults at A$193.99.
• Estimate auto-convert and milestone schedules sit behind Plus, and there is no NDIS layout.

Price: at the time of writing, free, or Plus at AUD $30 per month; 2.2% on online card payments. Best for: private-pay clinicians whose clients want to tap a card.

5. Xero — Best when a bookkeeper already runs your practice

Xero is accounting software rather than an invoicing app, and that distinction decides whether it is right for you. It is the correct answer when your bookkeeper already works in Xero and wants invoices, bank feeds, GST and BAS in one system instead of three.

On the mixed-funding test it is capable but slow: it sends invoices and handles Australian GST, but you build the NDIS layout yourself and you are learning a general ledger to do it. There is no free plan, and for a solo clinician on 20 invoices a month it is more software than the job needs. Add clinicians, payroll and a BAS and the picture flips.

Pros

• Invoicing, bank reconciliation, GST and BAS in one system your accountant already knows.
• Bank feeds mean the quarterly BAS is assembled from real transactions, not rebuilt at the deadline.

Cons

• No free plan, and no allied health or NDIS layout to start from.
• Considerably more software than a solo clinician needs, with the learning time to match.

Price: paid plans available — check current pricing. Best for: practices whose books a bookkeeper already keeps in Xero.

6. Rounded — Best Australian app for a sole-trader clinician

Rounded is Australian-built specifically for sole traders and freelancers, and it puts invoicing, expenses and tax estimates in one place. For a clinician who has never set money aside for tax, the estimate alone pays for the subscription.

It sends invoices and handles Australian tax properly, and it is the cheapest paid option here: Solo is $99 a year regular AUD at the time of writing, against A$168 for InvoiceSonic Pro billed annually. That is a genuine reason to pick it over our number one if a tax estimate matters more than an NDIS layout. There is no free plan and no NDIS template we could confirm.

Pros

• Built in Australia for sole traders, so expenses and tax estimates are ATO-shaped.
• Solo is $99 a year regular AUD at the time of writing, cheaper than most paid apps here.

Cons

• No free plan at all, so you cannot run a quiet month on it for nothing.
• No NDIS layout, and promotional pricing varies, so check what year two costs.

Price: at the time of writing, Solo $99 per year regular and Pro $70 per month regular in AUD; promotional pricing varies. Best for: sole-trader clinicians who want invoicing, expenses and a tax estimate in one app.

7. Wave — Best free invoicing with basic books attached

Wave is free in Australia at the time of writing and gives you invoicing and light accounting in the same account. On a nil budget that is more than several paid apps hand you.

It fails the tax half of the mixed-funding test harder than the others. Wave's GST handling is generic rather than ATO-shaped, precisely the wrong weakness when your invoices swing between taxable and GST-free depending on the funding source. Use it for invoicing and expenses, and keep every GST decision with your accountant.

Pros

• Free in Australia at the time of writing, with invoicing and basic accounting together.
• No trial card and nothing to cancel, so a new practice can test it freely.

Cons

• GST handling is generic rather than ATO-shaped, a poor fit for mixed funding.
• Australian support is thin, and payments and payroll are US and Canada centric.

Price: free in Australia at the time of writing. Best for: new practices with no budget who will check every GST treatment themselves.

8. Bookipi — Best budget app for recurring billing

Bookipi is a simple invoice app that syncs between web and mobile, and it lists overdue reminders and recurring invoices even on the free plan. For a client booked into a ten-week block, that matters.

The catch is volume. Free stops at 3 invoices a month, and a caseload of 20 burns through that in the first week, so the honest read is that Bookipi passes on Starter and not on free.

Pros

• Recurring invoices and overdue reminders even on the free plan.
• Web and mobile stay in sync, so an invoice started between appointments finishes on the laptop.

Cons

• 3 free invoices a month is far too few for a real caseload.
• Priced in USD, so the cost moves with the AUD, and there is no NDIS layout.

Price: at the time of writing, free for 3 invoices a month; Starter US$9.99 per month; Professional US$52 per month. Best for: part-time clinicians with a small caseload who want billing to repeat itself.

What to look for in invoicing software for allied health

Allied health billing is not high volume, it is high variety. Twenty invoices a month is nothing; twenty invoices in three shapes, with two tax treatments and three payers, is the problem.

• Somewhere to put NDIS details without a rebuild. Participant name and NDIS number, support item number, service dates, hours and your ABN all have to fit, every time. Our guide to invoicing software for NDIS providers goes deeper.
• Control of the tax line, invoice by invoice. GST treatment depends on the service and the funding source, and most NDIS supports are GST-free where they are a reasonable and necessary support in a plan. An app that forces one rate onto everything is wrong half the time, and only the ATO or your accountant can say which half.
• An invoice you can address to someone other than the client. Plan managers, DVA and other third-party payers receive the invoice even though the participant received the service. Confirm each payer's requirements with that payer; they differ, and no app sets them.
• Automatic reminders. Third-party payers process in batches, and a missed batch means another month. Our guide on chasing overdue invoices covers the rest.
• A tax invoice that meets the ATO's list. Where you are registered for GST it must carry the words "Tax invoice", your identity and ABN, the date, a description of what was supplied, the GST amount, and the buyer's identity or ABN for sales of $1,000 or more. Full list in our tax invoice requirements guide.
• Whether you need to register for GST at all. Registration is compulsory at A$75,000 of turnover. What counts towards that figure when part of your work is GST-free is a question for the ATO or your accountant, so read the GST registration threshold, then get advice on your own numbers.

Which one should you choose?

Run the numbers at 20 invoices a month. At the time of writing that is A$0 with the free generator, Zoho Invoice or Wave; A$168 a year with InvoiceSonic Pro billed annually; $99 a year with Rounded Solo; US$9.99 a month with Bookipi Starter; and A$1,024.27 a year in card fees with Square if all twenty are A$193.99 card payments. The subscription is almost never the expensive part.

• If you bill private clients only, a handful of invoices a month → the free Australian tax invoice generator, and email the PDF.
• If your caseload mixes private, NDIS and plan-managed work → InvoiceSonic, for the NDIS template plus reminders and open tracking on Pro.
• If you want sending and a saved payer list for nothing → Zoho Invoice, and accept the dense interface.
• If a tax estimate matters more to you than an NDIS layout → Rounded Solo, at $99 a year regular AUD.
• If clients expect to tap a card at the end of the session → Square Invoices, with the 2.2% priced into your fee.

When not to use InvoiceSonic or a free generator. If your real problem is the appointment book, clinical notes and claiming, none of the eight tools here is the answer. Clinical practice management systems built for allied health, such as Cliniko, Nookal, Halaxy and Power Diary, are a different category: they hold the diary, the clinical record and the claiming workflow, and invoicing is one module inside that. Once you have staff, payroll and a quarterly BAS you are in accounting territory, and Xero or MYOB is the right purchase. Rounded is the better buy if a tax estimate matters more than an NDIS layout, at $99 a year regular AUD against A$168. A free PDF generator, ours included, stops being right the moment you are chasing a plan manager. And no tool here should be called compliant with any funding scheme: the requirements sit with the scheme and with you, and the software only formats the page.
