Use this page to prepare an invoice for work sold to an Australian customer or by an Australian business. The finished invoice should identify the seller, the buyer when required, the work supplied, the amount due, the GST treatment, and the payment deadline. Australia does not set one national B2B invoice payment term, so the due date should match the contract or the terms printed on the invoice.
Australian tax invoices are built around GST and the ABN. A GST-registered supplier charges 10% GST on taxable supplies, with GST normally equal to one-eleventh of the GST-inclusive price. A business generally must register for GST once GST turnover reaches A$75,000, or A$150,000 for non-profit organisations. Taxi, limousine, and ride-sourcing providers must register regardless of turnover.
A valid Australian tax invoice must clearly identify itself as a tax invoice and show the seller's identity and ABN, the issue date, what was sold, the quantity and price, the GST amount payable, and the extent to which each sale is taxable. The ABN is an 11-digit identifier issued through the Australian Business Register, and it is the supplier tax-registration identifier shown on Australian tax invoices.
For a taxable sale over A$82.50 including GST, a GST-registered supplier must provide a tax invoice within 28 days if the customer requests one. If the total payable on a tax invoice is A$1,000 or more, the invoice must also show the buyer's identity or the buyer's ABN. For example, a consulting invoice can list project work, hours, rate, GST, total due, buyer name, and payment terms.
GST can appear as a separate amount or through a statement that the total price includes GST when GST is exactly one-eleventh of the total price. Separate GST lines make review easier when an invoice includes taxable and non-taxable sales. The invoice should also state enough supply detail for the customer to match the charge to the order, statement of work, or approved timesheet.
Foreign-currency invoices need extra care. If a tax invoice is issued in a foreign currency, it must either show the GST payable in Australian currency or provide enough information to work out the GST amount in Australian currency. Australia uses the Peppol framework for eInvoicing, but ordinary businesses are not subject to a general national requirement to issue B2B invoices through Peppol.
A one-off invoice app is enough when you have a simple job, a known client, and the correct GST and ABN details ready. It works well for a single service invoice, a short project, or a client request for a tax invoice after a taxable sale over A$82.50 including GST. The main limit is continuity: the invoice exists, but the approval trail and billable source data sit somewhere else.
A managed workflow matters when multiple people log time, some tasks are non-billable, or rates change by project, task, or member. Everhour supports billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports for billable time, non-billable time, billable amount, and cost before invoice preparation.

An Australian invoice needs to be a tax invoice when a GST-registered supplier makes a taxable sale and the customer needs a GST record. For a taxable sale over A$82.50 including GST, the supplier must provide a tax invoice within 28 days if the customer requests one. Non-registered sellers should not charge GST.
The supplier should use its ABN on an Australian tax invoice. The ABN is the Australian Business Number, an 11-digit identifier issued through the Australian Business Register. It identifies the seller for tax invoice purposes. Buyer details become mandatory when the total payable on the tax invoice is A$1,000 or more.
Yes. A tax invoice can show the GST amount separately, or state that the total price includes GST when GST is exactly one-eleventh of the total price. A separate GST amount is clearer when the invoice includes more than one line item, mixed taxable treatment, or a client accounting process that checks tax by line.
Australia uses the Peppol framework for eInvoicing, but ordinary businesses are not subject to a general national requirement to issue B2B invoices through Peppol. A PDF or other invoice format can still be used when it contains the required tax invoice details and matches the buyer's delivery requirements.
The common mistake is treating an invoice as complete while leaving out GST status, the supplier ABN, or buyer identity on invoices of A$1,000 or more. A second mistake is issuing a foreign-currency tax invoice without showing GST payable in Australian currency or enough information to calculate the GST amount in Australian currency.
Everhour lets admins set project billing status, mark specific tasks non-billable, use custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so invoice totals come from reviewed work instead of rebuilt spreadsheets.
Everhour Billing & Invoicing turns tracked billable time and expenses into client invoices. Users can select uninvoiced time and expenses, preview the breakdown, group line items by project, task, person, or date, and generate an invoice while excluding non-billable work.
Track billable and non-billable work by project, task, and member before invoicing. Everhour gives teams cleaner billing records and stronger invoice preparation.
