An Australian service invoice template is a reusable document for listing work performed, the amount due, and how and when to pay. Use the blank template below as a starting point; if you are registered for GST, make sure the document also meets the Australian Taxation Office’s requirements for a tax invoice when those apply.
What a service invoice is for
A service invoice asks a customer to pay for work already completed or for an agreed stage of work. It records the transaction for both parties and helps make clear what was supplied, what it cost, and whether GST is included. Common examples include invoices from tradespeople, consultants, tutors, cleaners, designers, and repair services.
An invoice is not the same thing as a quote. A quote sets out a proposed price before the customer agrees to the work; an invoice requests payment under the agreed arrangement. A receipt, in turn, confirms that payment has been received. You may issue an invoice before or after work depending on your agreement, such as for a deposit, a milestone, or completed work.
There is no single mandatory Australian layout for every service invoice. A consistent format is useful, but the details required for a tax invoice depend on factors such as GST registration and the invoice total. Keep a copy of each invoice and any related quote, approval, or payment record.
Australian tax invoice requirements
A business generally needs to be registered for GST before it charges GST and issues a tax invoice. If you are not registered for GST, do not add a GST amount to your prices or describe an invoice as a tax invoice. You can still send an ordinary invoice requesting payment. Registration and reporting obligations depend on the business’s circumstances, so check current ATO information or ask a qualified professional if you are unsure.
When a customer needs a tax invoice for a taxable sale, the supplier must provide one within 28 days of the customer’s request. For a sale of less than $1,000, a tax invoice generally includes:
- The words “Tax invoice”.
- The seller’s identity and ABN, plus the date the invoice was issued.
- A description of the services supplied, including enough detail to identify them.
- The price and the GST amount, or a clear statement that the total price includes GST.
For a tax invoice totalling $1,000 or more, it must also identify the buyer or show the buyer’s ABN. Where a sale includes both taxable and GST-free items, the invoice needs to make the GST treatment clear for the relevant items. These are general requirements, and the precise treatment can depend on the transaction. Do not assume that adding an ABN alone makes a document a tax invoice.

For a GST-registered supplier issuing a tax invoice, label it “Tax invoice” and include the relevant GST details described above. Remove fields that do not apply, but keep enough information to explain the charge.
How to complete the invoice
Fill in the template so the customer can recognise the transaction and check the amount without having to guess. A useful sequence is:
- Identify the parties. Enter your trading or business name, contact details and ABN, and the customer’s name. Include the customer’s ABN or identity on a tax invoice of $1,000 or more.
- Give the document a reference. Use a unique invoice number and an issue date. A numbering sequence helps you find records later; avoid reusing a number for a different invoice.
- Describe the work. State the service, relevant date or service period, and any stage or location that helps identify it. For example, “replace laundry tap and test for leaks” is clearer than “plumbing”.
- Show how the total was worked out. List hours, units, agreed rates, and separately charged materials or expenses where relevant. If the price is a fixed fee, say so rather than inventing a number of hours.
- Make the amount payable clear. Show the subtotal, any applicable GST, the total, payments already received, and the remaining balance. State the due date and how the customer can pay.
Keep descriptions factual and aligned with the work actually agreed and supplied. If the customer approved extra work, record that approval and identify the additional charge separately. This can prevent a later disagreement about whether the amount was included in the original price.
Payment terms, deposits and expenses
Put the due date or payment period in plain language, such as “Payment due 14 days from invoice date”, if that reflects the agreement. Do not rely on the customer to infer terms from a previous invoice. Payment timing, deposits, cancellation charges, and late-payment terms should be agreed clearly; an invoice should not be used to introduce a new charge the customer did not agree to.
For a deposit or staged project, identify what the payment covers—for example, “30% deposit for approved installation booking”—and show how it affects the remaining balance. When billing a milestone, describe the milestone and avoid presenting the full project price as still owing if earlier instalments have been paid. For reimbursed materials or travel, list the items and amounts clearly and follow the arrangement made with the customer. GST treatment may vary with the transaction, so seek qualified tax advice if you cannot determine how to report a charge.
Filled-in example
Sample — fictional details only: Harbourline Garden Repairs, 12 Example Lane, Seaview NSW; ABN 00 000 000 000 (dummy number, not a valid ABN); Invoice 1042; issued 2 November 2026; customer: Alex Example; work date: 31 October 2026. Description: “Garden irrigation inspection and repair”; labour: 2 hours at $100, $200; replacement connector: $20; subtotal: $220; GST: $22; total due: $242; payment due: 16 November 2026.
This example assumes, only for illustration, a GST-registered supplier making a taxable supply and rates stated before GST. The customer and business details are invented, and the dummy ABN must not be used. In an actual invoice, show whether listed prices include GST and calculate the figures according to the real transaction.
Common invoice mistakes
- Calling every invoice a tax invoice. Use that label only when the document is being issued as a tax invoice and the supplier’s GST status and transaction allow it.
- Adding GST without being registered. An ABN does not by itself mean a business is registered for GST or entitled to charge it.
- Using vague descriptions. “Services” may leave the customer uncertain. Name the task, work period, or project stage.
- Leaving out the payment status. If a deposit or part-payment has already been received, show it and state the balance still due.
- Mixing up issue and due dates. Label both dates clearly so the payment deadline is not mistaken for the invoice date.
- Sending incorrect details. Check arithmetic, ABN, customer information, and payment instructions before sending. If you correct an issued invoice, keep a clear record of the correction rather than silently changing the copy held by the customer.
For invoices sent electronically, use a reliable delivery method and keep a copy of what was sent. Share only payment details the customer needs; do not include unrelated personal or sensitive information.
Choosing and keeping an invoice format
A printable template is suitable when you issue invoices occasionally and can keep organised copies. A spreadsheet or document can make repeat work faster, while dedicated invoicing systems may offer automatic numbering, reminders, and record exports. The format does not replace the need for accurate details or appropriate GST treatment. Choose one you can maintain consistently and that lets you retrieve invoices if a customer asks about a past charge.
Keep invoices with related quotes, approvals, work notes, and evidence of payment. Record-keeping periods and tax obligations can depend on your circumstances; consult current official guidance for applicable retention rules. For situation-specific tax or legal advice, ask a qualified professional.
Frequently Asked Questions
What must an Australian service invoice include?
At minimum, identify the supplier and customer, describe the service, show the amount and payment terms, and provide a date and useful reference number. If it is a tax invoice, additional details apply, including GST information and, for a total of $1,000 or more, the buyer’s identity or ABN.
Can I send an invoice if I am not registered for GST?
Yes. You can issue an ordinary invoice for payment, but you must not charge GST or call it a tax invoice if you are not registered for GST. Check your circumstances against current ATO guidance if you are unsure about registration.
When should I issue a tax invoice?
If a customer requests a tax invoice for a taxable sale, the supplier generally has 28 days to provide it. Whether a transaction is taxable and what details belong on the invoice depend on the facts of the sale.
Do I need to put the customer’s ABN on every invoice?
No. For a tax invoice totalling $1,000 or more, it must identify the buyer or include the buyer’s ABN. The buyer’s ABN is not a general requirement for every invoice.
Can I charge a late fee on an overdue invoice?
Only include a late fee where it is permitted by the terms agreed with the customer and applicable requirements. State any agreed fee clearly; if you need advice about enforceability or a dispute, ask a qualified professional.
