Best Invoicing Software for NDIS Providers in Australia (2026): 8 Tools Compared

The best invoicing software for NDIS providers in Australia in 2026 is InvoiceSonic, because it is the only tool here with a dedicated NDIS invoice template and it can send and chase the invoice as well. If you support one or two participants and only need a compliant PDF today, the free generator on this site builds one in the browser with no signup. If you roster staff, run SIL houses or lodge bulk claims, none of these eight is enough and you need dedicated NDIS practice-management software. We put all eight through the plan-manager test: does the invoice pass a plan manager's checks first time?

Quick comparison

"Not listed" means exactly that: the tool's own Australian pricing or feature page did not state the feature at the time of writing, so we have not marked it a yes. No tool in this list is NDIS-approved or NDIS-registered — that status belongs to providers, not to software — and only one of the eight ships an NDIS layout out of the box.

How we tested: the plan-manager test. Three questions per tool. Can the invoice carry the participant's name and NDIS number as their own labelled details rather than buried in a description? Can each line hold the support item number from the NDIS Price Guide or Support Catalogue alongside the service dates and hours delivered? And can you issue it GST-free, with your ABN showing and no 10% line added out of habit?

Three billing routes, three different jobs. Plan-managed participants are the reason this test exists: you send the invoice to a registered plan manager, a third party who checks it against the plan before paying, so a formatting fault is caught by someone who does not know you and does not ring to ask. Self-managed participants are billed directly and claim the money back from the NDIA themselves, which usually means a plainer invoice and a faster answer. NDIA-managed supports are claimed through the myplace provider portal rather than emailed as an invoice, so your software is your own record of the work rather than the claim channel. Most solo support workers end up doing all three, from the same template.

What a rejection actually costs. Say you bill A$4,000 of supports a month. That is about $133 a day of income. A rejected invoice is not a five-minute fix: it goes back for correction and rejoins the next processing run, which on the reports we see costs 14 to 21 days. Call it 15. Now note that a formatting fault is almost never one invoice — a missing NDIS number, the wrong support item number or a 10% GST line on a GST-free support comes off the template, so every invoice you send that month carries it. Fifteen days at $133 a day is roughly A$2,000 permanently out of your account: you take the hit once, and the hole stays open for as long as you keep billing at the later cadence. Fixing the template is worth $2,000 of working capital before it is worth a minute of your time.

Who fails the test. Only InvoiceSonic passes all three questions with a purpose-built layout. The free generator on this site fails question one and two on labelling — you type the NDIS number and support item numbers into the description yourself — and fails outright on sending, because it makes a PDF and nothing else. Zoho Invoice, Square Invoices, Xero, Bookipi, Rounded and Wave all send properly formatted Australian invoices, but every one of them makes you build the NDIS layout out of generic invoice fields, and none of them stated an NDIS template at the time of writing. Wave is the weakest on question three: its GST handling is generic rather than ATO-shaped, which is a poor place to start when the whole point is a GST-free supply with an ABN on it.

1. InvoiceSonic — Best overall

InvoiceSonic is the only tool in this comparison with a dedicated NDIS invoice template, which is the difference between filling in a form and designing one. The layout a plan manager expects is already there, so the participant's details, the support lines and the dates sit where a checker looks for them.

It passes all three questions. You still type the participant's NDIS number and the support item number from the Support Catalogue — no invoicing tool knows your participant's plan — but the fields exist and they stay in the same place on every invoice you send. On Pro, recurring invoices cover participants you support every week, and automatic reminders chase a slow payer without another email from you. Invoice open tracking shows the moment your invoice is looked at, which is genuinely useful when you are wondering whether a plan manager received it. Payment is by bank transfer or PayID with no gateway to set up and no InvoiceSonic transaction fee, so a $4,000 month lands as $4,000. Australian handling is built in — ABN field, BSB format, GST labelling — as part of localised support across 19 countries. There is an iPhone app but no native Android app, so Android users add the web app to the home screen.

Pros

• A dedicated NDIS invoice template, so the layout is right before you start typing.
• Recurring invoices and automatic reminders on Pro for participants with weekly supports.
• Bank transfer and PayID with no InvoiceSonic transaction fee, and annual Pro is price-locked while the subscription is active.

Cons

• It is not NDIS practice-management software: no rostering, timesheets or staff management, and it does not lodge claims in the myplace provider portal for you.
• A free account is capped at 3 saved invoices, 1 tracked email send and 1 automatic reminder a month, and the 7-day Pro trial requires a card up front.

Price: at the time of writing, the free plan is A$0 and the first invoice needs no sign-up and no credit 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: sole support workers and small NDIS providers billing plan-managed and self-managed participants who want the invoice right first time and chased automatically.

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

Invoice-Generator.com.au is a free tax invoice generator that builds a finished PDF in your browser with no signup, no watermark, no ads and no invoice limit. It is the right tool when a plan manager wants an invoice for last fortnight's supports today and you are not about to subscribe to anything to send it.

Everything you type stays in the browser, which matters more here than in most trades: an NDIS invoice carries a participant's name, their NDIS number and often their address, and none of that leaves your device. The Australian tax invoice generator has an ABN field, a 10% GST line and a live compliance checklist that flags a missing ABN before you send. Because it is built around the standard 10% tax invoice, check the GST line reads correctly for a GST-free support before you send it, and put the participant's NDIS number and each support item number into the line descriptions yourself. If you are billing as an individual, the sole trader invoice generator is the shorter path, and our guide on how to write an invoice covers the wording.

Pros

• Free forever, no signup, no watermark, no invoice limit, and participant details never leave your browser.
• The compliance checklist catches a missing ABN before a plan manager does.

Cons

• No NDIS template, so the participant's NDIS number and every support item number are typed into the description each time.
• No sending, tracking, automatic reminders, saved participant list or payment collection — it makes the document and stops.

Price: free, always. Best for: support workers with one or two participants, and anyone who needs a compliant PDF in the next five minutes.

3. Zoho Invoice — Best free tool that actually sends

Zoho Invoice is free — Zoho states no cost and no contracts — and unlike a PDF generator it sends the invoice, saves the participant as a contact and keeps the history. For an NDIS provider that history is the point: when a plan manager queries a February support, you want the sent invoice, not a folder of PDFs.

On the plan-manager test it half-passes. It sends, it formats an Australian invoice properly and it stores what you sent, but there is no NDIS template, so you build the layout out of generic fields and then have to remember it every time. Automatic reminders were not stated on the Australian page at the time of writing, so confirm that before you rely on it for chasing. The trade-off is the surroundings: Zoho Invoice is the front door to a very large product suite, the interface is dense next to a single-purpose invoicing app, and real support is a paid-suite affair.

Pros

• Genuinely free with no contract, and it sends and stores invoices rather than only building a PDF.
• Multi-language invoicing across 19-plus languages, useful for participants and families who prefer another language.

Cons

• No NDIS template, so the participant's NDIS number and support item numbers live wherever you decide to put them.
• Dense interface, a large upsell suite behind it, and automatic reminders are not listed.

Price: free at the time of writing. Best for: providers who want sending, a saved participant list and an invoice history for A$0 and can live with a busy interface.

4. Square Invoices — Best for self-managed participants paying by card

Square Invoices gives you unlimited free invoices, estimates and automatic reminders, and the payer can settle by tapping a card link in the email. That is a real advantage with a self-managed participant or a family member who wants it done now rather than at the end of the month.

It half-passes. Automatic reminders are on the free plan and the Australian invoice format is fine, but there is no NDIS template and estimate auto-convert and milestone payment schedules sit behind Plus. The real cost is the card fee, which is easy to underestimate. At 2.2% on online card payments, A$4,000 of monthly supports is $48,000 a year and 2.2% of that is $1,056 a year — more than five years of InvoiceSonic Pro billed annually at A$168, and roughly half of the $2,000 a single template fault costs you. The same participants paying by PayID or bank transfer cost nothing.

Pros

• Unlimited free invoices with automatic reminders on the free plan.
• Card payment straight from the invoice, so a self-managed participant can pay the same day.

Cons

• 2.2% on online card payments is $1,056 a year on $48,000 of supports.
• No NDIS template, and milestone schedules and estimate auto-convert are Plus only.

Price: at the time of writing, free, or Plus at AUD $30 per month; 2.2% on online card payments. Best for: providers whose self-managed participants want to pay by card and who have written the 2.2% into their rates.

5. Xero — Best for GST-free coding with a bookkeeper

Xero is accounting software, not an invoicing app, and that distinction decides whether it belongs here. It is the right answer when a bookkeeper already runs your books and the GST-free treatment of your supports has to survive into your BAS rather than just onto a PDF.

That is where it earns its place on this test. If most of what you bill is GST-free and a small slice — say a service you also sell privately — is not, the tax coding has to be correct at the line level and then reported correctly, and that is what accounting software is built to do. Confirm the tax rate behaviour on a trial before you commit. Against it: there is no free plan, there is no NDIS template, and for a sole support worker sending a handful of invoices a month it is considerably more software than the job needs.

Pros

• Invoicing, bank feeds, GST and BAS in one system your accountant already knows.
• Line-level tax treatment carries through to reporting rather than stopping at the invoice.

Cons

• No free plan, and no NDIS layout — participant and support item details are yours to structure.
• Overkill for a solo operator, and it is a general ledger with invoicing inside it rather than an invoicing tool.

Price: paid plans available — check current pricing. Best for: growing NDIS providers with a bookkeeper, mixed GST treatment and a quarterly BAS.

6. Bookipi — Best budget app with recurring invoices

Bookipi is a simple invoice app that syncs between web and mobile, and it lists recurring invoices and overdue reminders on every plan including free. For weekly supports for the same participant, recurring billing is the feature that removes the most typing, and Bookipi is the only tool here besides InvoiceSonic that publishes it.

The catch is volume. The free plan stops at 3 invoices a month, which covers about three participants billed monthly and nothing more, so the honest read is that Bookipi passes on Starter rather than on free. Starter is priced in US dollars, so your invoicing cost moves with the exchange rate. There is no NDIS template, so the layout is on you, and that matters more here than in a trade where nobody checks the paperwork.

Pros

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

Cons

• 3 free invoices a month is very few once you support more than a couple of participants.
• Priced in USD, so the cost of your invoicing 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 support workers with two or three participants who still want the billing automated.

7. Rounded — Best for a sole support worker's invoicing and tax

Rounded is Australian-built specifically for sole traders and freelancers, and it does invoicing, expenses and tax estimates in one place. Independent support workers are sole traders with kilometres, phone bills and training costs, and the tax estimate is the feature that pays for the subscription.

It sends invoices and handles Australian tax properly, and the price is a genuine argument against our number one: Solo is $99 a year regular AUD at the time of writing, less than InvoiceSonic Pro billed annually at A$168, and it tracks expenses and estimates your tax as well. What it does not do is give you an NDIS layout, and there is no free plan at all, so you cannot run a quiet month on it for nothing. Promotional pricing varies, so check what year two costs.

Pros

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

Cons

• No free plan, and no NDIS template or participant-specific fields.
• Pro is $70 a month regular AUD and promotional pricing varies, so the second year may not match the first.

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

8. Wave — Best free invoicing with basic books attached

Wave was free in Australia at the time of writing and gives you invoicing and light accounting together, which is more than most free tools offer. If your budget is genuinely zero and you still want a set of books behind the invoices, it belongs on the shortlist.

It is last here for one reason that matters on this test. Its GST handling is generic rather than ATO-shaped, and the Australian support behind it is thin, which is an uncomfortable combination when the invoice you are sending is a GST-free supply with an ABN on it and a plan manager is checking. Payments and payroll are built for the United States and Canada, so treat those parts as unavailable rather than optional. There is no NDIS template.

Pros

• Free in Australia at the time of writing, with invoicing and basic accounting in one place.
• Keeps an invoice history and a ledger without a subscription.

Cons

• GST handling is generic rather than ATO-shaped, and Australian support is thin.
• Payments and payroll are US and Canada centric, and there is no NDIS layout.

Price: free in Australia at the time of writing. Best for: providers on a zero budget who want invoices and simple books together and will check the GST wording themselves.

What to look for in invoicing software for NDIS providers

NDIS billing is checked billing. Someone who has never met you reads the invoice against a plan before any money moves, so the layout is worth more than the feature list. These are the six things that decide whether an invoice clears first time.

• A place for the participant's name and NDIS number. These belong in labelled details, not appended to a line description where a checker has to hunt for them. This is the single most common reason a first invoice comes back.
• Support item numbers, service dates and hours on every line. Each line should show the support item number from the NDIS Price Guide or Support Catalogue, the date the support was delivered and the hours. Never guess a support item number or a price limit — take both from the participant's plan and the current Support Catalogue.
• GST-free handling. Most NDIS supports are GST-free where they are a reasonable and necessary support in a participant's plan, so your invoice will often show no GST even though you are registered for GST. Adding 10% out of habit is a rejection. Confirm your own circumstances with the ATO or your accountant — this is a tax question about your business, not a setting in an app.
• Your ABN on every invoice. Without an ABN the payer may be required to withhold 47% of the payment, and the wider tax invoice requirements still apply to the parts of your work that are taxable.
• Automatic reminders. Plan managers pay from a queue and things get missed. A reminder on the due date and another a week later recovers most of it without a phone call; our guide on how to chase overdue invoices in Australia covers what to do when that fails.
• Which management type you are billing. Plan-managed goes to the plan manager, self-managed goes to the participant, and NDIA-managed is claimed in the myplace provider portal. Software that stores participants separately saves you sending the wrong invoice to the wrong place.

Which one should you choose?

Run the numbers on A$4,000 of monthly supports. At the time of writing that costs 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 once you pass three invoices, and $1,056 a year in card fees with Square if everyone taps a card. Set all of that against the roughly A$2,000 a single template fault takes out of your account, and the subscription stops being the number that matters.

• If you bill plan-managed participants and want the invoice right first time → InvoiceSonic, on Pro if you have weekly supports to repeat.
• If you support one or two participants and send a few invoices a month → the free Australian tax invoice generator, and email the PDF.
• If you want sending, a participant list and history for nothing → Zoho Invoice, and accept the dense interface.
• If your participants are self-managed and want to pay by card → Square Invoices, with the 2.2% priced into your rates.
• If you are a sole trader who also needs expenses and a tax estimate → Rounded, at $99 a year regular AUD for Solo.

When not to use InvoiceSonic or a free generator. None of the eight tools on this page is an NDIS practice-management system, and none of them is NDIS-approved or NDIS-registered — that status applies to providers, not software. Once you are rostering support workers, running SIL houses, tracking shift-based pay or lodging bulk claim files, an invoicing app is the wrong tool and dedicated NDIS software is what you need: InvoiceSonic does no rostering, timesheets or staff management, and a free PDF generator does not even send. If your books are the problem rather than your invoices — mixed GST-free and taxable income, a quarterly BAS, a bookkeeper — that is accounting software territory, so Xero or MYOB. And if you want tax and expenses handled alongside the invoicing, Rounded is Australian-built for sole traders and Solo is cheaper per year than InvoiceSonic Pro billed annually at the time of writing. Nothing on this page is tax advice: check your GST position with the ATO or your accountant.
