A free invoice maker takes the friction out of billing: you fill in your business name, ABN, the client's details and your line items, then watch a tidy A4 tax invoice build in real time with GST calculated at 10%. No spreadsheet formulas, no fiddly Word templates, no subscription. When it looks right, you download a PDF or print it and send it straight to the client. Built for Australian conditions, the tool handles the things the ATO actually checks: the words "Tax Invoice", your ABN, a clear GST breakdown and the total payable.

What makes a valid Australian tax invoice
If you are registered for GST, the ATO requires your document to be a valid tax invoice for your client to claim a GST credit. For sales of $82.50 (including GST) or more, a tax invoice must show seven things: the words "Tax Invoice", your business or trading name, your ABN, the date the invoice was issued, a brief description of each item sold including quantity and price, the GST amount payable (or a statement that the total price includes GST), and the extent to which each item includes GST. For sales of $1,000 or more, you must also include the buyer's identity or ABN. If you are not registered for GST, do not charge GST and do not call it a "Tax Invoice": use the heading "Invoice" instead, and you can still show your ABN. Getting the heading and ABN right matters. If you do not quote an ABN on an invoice, the payer may be required to withhold 47% of the payment under the no-ABN withholding rules, which delays your cash. This tool puts the right fields in the right places so the document stands up to scrutiny from both your client's bookkeeper and the ATO. Use sequential invoice numbers (for example INV-0001, INV-0002) so your records reconcile cleanly at BAS time and nothing slips through the cracks. Keep a copy of every invoice you issue for five years, which is the standard ATO record-keeping period for GST and income tax.
Handling GST correctly at 10%
GST in Australia is a flat 10% on most goods and services. The arithmetic trips people up, so it helps to be deliberate. If you quote prices excluding GST, the GST is simply the subtotal multiplied by 10%, and the total is the subtotal plus that GST. If you quote GST-inclusive prices, the GST component is the total divided by 11, not by 10: a $110 inclusive price contains $10 of GST. This tool calculates GST automatically so you avoid rounding errors, but understanding it lets you sanity-check the figures before you send. You only charge GST if you are registered, which is mandatory once your turnover reaches $75,000 a year (or $150,000 for non-profits). Some supplies are GST-free, including most basic food, certain health and education services, and exports. If an invoice mixes taxable and GST-free items, show the GST clearly against each line so your client can see exactly what is and is not taxed. Round GST to the nearest cent per the ATO's rules. When you lodge your BAS, the GST you have collected on these invoices is what you remit, so accurate invoices feed directly into accurate activity statements. Treat the invoice as the first link in your tax chain, not an afterthought.
Getting paid faster
A clean invoice is only useful if it gets paid. The single biggest lever is clear, short payment terms stated on the document itself: "Payment due within 7 days" or "Due on receipt" outperforms a vague "Net 30" for most small Australian businesses, because the longer the window, the longer the average wait. Put your payment details where the client cannot miss them: BSB, account number and account name for bank transfer, plus a PAYID or a card payment link if you accept them. Always include your invoice number and ask the client to use it as the payment reference so you can match money to invoice without guesswork. Send the invoice the moment the job is done, not at the end of the month: every day of delay is a day added to your wait. For larger jobs, consider a deposit upfront and progress claims rather than one lump sum at the end, which protects your cash flow and reduces the amount at risk. If a payment goes past due, a polite reminder a day or two after the due date recovers more than most people expect. The Australian Small Business Ombudsman recommends documenting terms in writing before work starts, and a professional, itemised invoice backs that up if a dispute ever arises.
When manual invoicing starts to cost you
Filling in one invoice by hand is quick. Doing it forty times a month, chasing each payment, then re-keying it all into your accounting software is where the hours disappear. Most owners we speak with are spending several hours a week on billing admin: copying client details, recalculating GST, manually following up overdue accounts, and reconciling payments against invoices one by one. That is time not spent on the work that actually grows the business. This is exactly the kind of repetitive, rules-based process that automation handles well. An automated flow can pull job details from your scheduling tool, generate and send the invoice, record it in Xero or MYOB, send reminders on a schedule, and flag only the accounts that genuinely need your attention. The manual invoice you are about to create is a perfect snapshot of the steps a system could run for you every single day. If billing has become a bottleneck rather than a five-minute task, it is worth looking at where automation could quietly give those hours back.

A cafe supplier in Sydney clears a backlog of month-end invoices, using sequential numbering and clear 7-day terms so the figures reconcile cleanly when they lodge their quarterly BAS.
Frequently asked questions
Is this invoice maker really free to use?
Yes. You can create, preview, download and print as many invoices as you like at no cost, with no subscription and no account required. The tool runs in your browser, calculates GST at 10% automatically, and produces a professional A4 PDF you can send straight to your client. It is offered as a genuinely free utility by Clever Ops.
Does the invoice meet ATO tax invoice requirements?
It includes the fields the ATO requires on a valid tax invoice: the words "Tax Invoice", your business name, your ABN, the issue date, a description of each item with quantity and price, and a clear GST breakdown. For sales of $1,000 or more, add the buyer's identity or ABN in the bill-to field. You are responsible for entering accurate details for your situation.
What if I am not registered for GST?
If you are not registered for GST, you must not charge GST and should not label the document a "Tax Invoice". Use the heading "Invoice" instead and leave the GST off. You can still show your ABN, which is wise: without an ABN on the invoice, the payer may have to withhold 47% of the payment under the no-ABN withholding rules.
How is GST calculated on the invoice?
GST is applied at 10% on taxable line items. If your prices exclude GST, the GST is the subtotal times 10%. If you enter GST-inclusive prices, the GST component is the total divided by 11. The tool handles the maths automatically and shows the subtotal, GST and total payable in the live preview, so you can check the figures before sending.
Can I add my bank details and payment terms?
Yes. Use the notes or terms field to add your BSB, account number, account name, any PAYID or card payment link, and your payment terms such as "Due within 7 days". Including clear payment details and a short due window, and asking the client to use your invoice number as the reference, is the simplest way to get paid faster and reconcile payments easily.
Do I need to keep copies of the invoices I send?
Yes. The ATO requires Australian businesses to keep records, including copies of invoices issued, for five years. Download a PDF of each invoice and store it somewhere safe, ideally alongside your accounting records. Sequential invoice numbers make this easier: they help you confirm nothing is missing and they keep your GST and income records tidy at BAS and tax time.
