You came here to prepare an invoice that an Australian client can read, approve, and pay without back-and-forth. The invoice should show who supplied the work, who received it, what was delivered, the amount due, GST treatment, and payment timing. For billable services, it also needs enough line-item detail to match the agreement, purchase order, or project record.
Australian invoice work centers on GST rules when the supplier is GST-registered. A tax invoice is required on request for a taxable sale over A$82.50 including GST, and the supplier must provide it within 28 days. For smaller sales, a simpler record may be enough, but clients often still expect a clear invoice for bookkeeping.
A valid Australian tax invoice clearly identifies itself as a tax invoice and shows the seller's identity, ABN, issue date, supply details, quantity and price, GST amount payable, and the extent to which each sale is taxable. The ABN is the supplier's 11-digit Australian Business Number issued through the Australian Business Register.
GST can appear as a separate amount, or the invoice can state that the total price includes GST when GST is exactly one-eleventh of the total price. If the total payable is A$1,000 or more, add the buyer's identity or buyer's ABN. That extra buyer detail prevents approval delays on larger invoices.
GST registration changes the invoice. A business generally must register once GST turnover reaches A$75,000. The threshold is A$150,000 for non-profit organisations, while taxi, limousine, and ride-sourcing providers must register regardless of turnover. A GST-registered supplier charges 10% GST on taxable supplies and issues tax invoices when the rules require them.
Foreign-currency invoices need special care. If the invoice uses another currency, it must show GST payable in Australian currency or give enough information to calculate the GST amount in Australian currency. Australia also supports Peppol eInvoicing, but ordinary businesses do not face a general national B2B requirement to issue invoices through Peppol.
A free invoice tool is enough when you need one clean document, a small batch of client invoices, or a quick tax invoice with GST fields and a due date. It works best when the time, rates, expenses, and client terms already live somewhere else and you only need to assemble the final document.
A managed workflow matters when billable time, project costs, approvals, and reporting need to stay connected after the invoice goes out. Everhour Reporting can group time and financial data with filters, date ranges, exports, and scheduled delivery, so invoice preparation starts from tracked work instead of reconstructed notes.

Australian invoice software for GST-registered suppliers should support GST fields because GST on a taxable supply is 10% of the value of that supply. A tax invoice also needs the GST amount payable or a statement that the total price includes GST when GST is exactly one-eleventh of the total price.
The supplier's ABN belongs on an Australian tax invoice. The ABN is an 11-digit identifier issued through the Australian Business Register. For a tax invoice totaling A$1,000 or more, the invoice must also show the buyer's identity or the buyer's ABN.
Australia uses Peppol for eInvoicing, but ordinary businesses do not have a general national B2B mandate to issue invoices through Peppol. A business can still use electronic invoicing voluntarily, while GST invoice content must still meet Australian tax invoice requirements.
Australian B2B invoices use the contract or invoice terms for payment timing because Australia does not set one national B2B invoice payment term. Put the due date directly on the invoice, and match it to the client agreement, purchase order, or standard account terms.
Missing GST or buyer-identification details creates approval friction. A tax invoice for A$1,000 or more must show the buyer's identity or buyer's ABN, and GST-registered suppliers need clear GST treatment. Finance teams pause invoices that lack the fields needed for GST records.
Everhour Reporting lets teams build reports with columns, grouping, filters, date ranges, and export formats such as CSV, Excel/XLSX, and PDF. For Australian billing work, that gives admins a clean source for billable time, costs, invoice status, and project totals before preparing invoices.
Everhour Billing & Invoicing turns uninvoiced billable time and expenses into client invoices. It calculates invoice amounts from rates, time, and billable expenses while excluding non-billable work, then marks invoiced time so the same work does not appear again in a later invoice.
Use Everhour reports to review billable time, costs, and invoice status before billing. Keep project records, exports, and scheduled summaries connected to Australian client invoicing.
