An Australian invoice should give the client enough detail to approve the charge, pay on time, and keep the record for GST reporting. Start with the seller name, ABN, issue date, invoice number, buyer details, payment due date, and a plain description of each supply. Add quantities, unit prices, GST treatment, total payable, and payment instructions.
GST-registered suppliers use the tax invoice format for taxable sales. For taxable sales over A$82.50 including GST, a GST-registered supplier must provide a tax invoice within 28 days if the customer requests one. The Australian Taxation Office also expects a tax invoice to identify itself as a tax invoice and show the seller's ABN.
The ABN is the supplier's tax-registration identifier on Australian tax invoices. It is an 11-digit Australian Business Number issued through the Australian Business Register. Place it near the seller name so the buyer can validate the supplier and process the invoice without extra email follow-up.
Australia's Goods and Services Tax applies at 10% on taxable supplies. 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 GST-inclusive price. If the invoice total is A$1,000 or more, include the buyer's identity or the buyer's ABN.
Australia does not impose one national B2B payment term for ordinary invoices. The due date usually comes from the contract or the invoice terms, so state it directly instead of relying on a default convention. A clear due date, accepted payment methods, and reference number reduce payment delays.
Peppol eInvoicing exists in Australia, but ordinary businesses do not face a general national B2B requirement to issue invoices through Peppol. A PDF or online invoice is still suitable for many client relationships, as long as the invoice contains the required tax invoice details and any client-specific purchasing information.
A single invoice works well for a one-time service, a small fixed-fee job, or a client that only needs a PDF with GST details. It also works when you already have clean notes for hours, expenses, rates, and approved scope. The risk appears when the invoice depends on scattered timesheets or memory.
Everhour supports a managed billing workflow by separating billable and non-billable time. Admins can set project billing status, mark specific tasks as non-billable, apply custom task rates, use member-rate exceptions, and report on billable time, non-billable time, billable amount, and cost before invoice totals are prepared.

A valid Australian tax invoice from a GST-registered supplier must show the seller's ABN. The ABN identifies the supplier for tax purposes and helps the buyer process the record. Non-GST invoices still commonly show the ABN because clients use it to verify the business.
A tax invoice with a total payable of A$1,000 or more must show the buyer's identity or the buyer's ABN. Below that amount, the seller details, ABN, issue date, supply description, price, and GST information carry the core tax invoice record.
A tax invoice can list the GST amount separately, or it can state that the total price includes GST when GST is exactly one-eleventh of the GST-inclusive price. A separate GST line is often clearer for clients because it shows the taxable amount and tax amount without extra calculation.
Australia uses the Peppol framework for eInvoicing, but there is no general national B2B mandate that forces ordinary businesses to issue invoices through Peppol. Client contracts, government procurement rules, or buyer systems can still require a specific delivery method.
An Australian B2B invoice should show the due date stated in the contract or invoice terms. The country does not set one national B2B payment term for ordinary commercial invoices, so the invoice should name the exact deadline, payment method, and payment reference.
Everhour lets admins set project billing status, mark individual tasks as non-billable, apply custom task rates, and use member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so only chargeable work feeds the billing review.
Track billable work before invoice day. Everhour separates chargeable and non-chargeable time, applies project and task rules, and gives teams cleaner billing totals for client invoices.
