Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
An estimate gives the customer a priced view of proposed work before you issue an invoice. It should name the seller, identify the customer, describe the work, show quantities or units, list prices, state GST treatment where relevant, and give an expiry date or approval window. The customer can accept, reject, or request changes before any billable work starts.
For Australian work, the estimate should prepare the information that later appears on a tax invoice. GST-registered suppliers use an ABN as the tax-registration identifier, and GST on a taxable supply is 10% of the value of that supply. A clear estimate prevents the approval from drifting away from the invoice that follows.
Start with the estimate number, issue date, seller name, seller contact details, ABN, customer name, customer contact, project description, line items, price, GST treatment, total, payment terms, and acceptance instructions. A service line can read: "Website content editing, 12 hours at A$95 per hour, taxable supply, GST included." Use line items detailed enough for the buyer to approve scope.
Payment timing belongs on the estimate even though Australia does not set a single national B2B invoice payment term. The contract or invoice terms usually set the due date, so write the intended term plainly, such as "Payment due 14 days from invoice date." Add exclusions, revision limits, travel costs, or deposit requirements when they affect the final bill.
GST registration changes the estimate. A business generally must register for GST once its GST turnover reaches A$75,000, with a A$150,000 threshold for non-profit organisations. Taxi, limousine, and ride-sourcing providers must register regardless of turnover. A GST-registered supplier should show whether prices include GST or list GST separately so the buyer knows the expected tax treatment.
Australian tax invoices have stricter rules than estimates, so build the estimate with those later fields in mind. A valid Australian tax invoice must identify itself as a tax invoice and show the seller's identity and ABN, issue date, supply details, price, GST amount payable, and taxable extent. For totals of A$1,000 or more, it must also show the buyer's identity or ABN.
A free estimate template is enough for a single job, a straightforward scope, or a client who only needs a price before approving work. It works best when you already know the rate, hours, GST treatment, and payment term. Save a copy of the accepted estimate because it becomes the reference point for the invoice and any later scope dispute.
A managed workflow becomes useful when approved estimates turn into tracked billable time, variable rates, expenses, and invoices. Everhour separates cost and billable rates, supports per-person defaults and per-project overrides, and preserves dated rate history. That structure keeps the approved estimate, actual work, and final invoice aligned without rebuilding the numbers by hand.

An estimate is not a tax invoice because it asks the customer to approve future work rather than billing for a completed taxable sale. After the sale happens, a GST-registered supplier must provide a tax invoice within 28 days if the customer requests one for a taxable sale over A$82.50 including GST.
A GST-registered supplier should show GST treatment on the estimate so the customer understands the expected final price. The estimate can list GST separately or state that prices include GST. The later tax invoice must show the GST amount payable or state that the total price includes GST when GST is exactly one-eleventh of the total price.
An estimate does not follow the full tax invoice field rules, but collecting the buyer's identity or ABN early prevents rework. Australian tax invoices totaling A$1,000 or more must show the buyer's identity or the buyer's ABN, so high-value estimates should capture that detail before approval.
An estimate can price work in a foreign currency if the customer accepts that commercial term. The later tax invoice has a GST requirement: if it is issued in a foreign currency, it must show the GST payable in Australian currency or provide enough information to work out the GST amount in Australian currency.
Peppol eInvoicing is available in Australia, but ordinary businesses do not have a general national requirement to issue B2B invoices through Peppol. An estimate can still be sent as a PDF, email, or business document unless a customer contract requires a specific format.
Everhour separates internal cost rates from client-facing billable rates, with per-person defaults and per-project overrides. Teams can price billable work by project, member, or task, then preserve dated rate history so older work keeps the rate that applied when the time was logged.
Everhour turns tracked billable time and expenses into invoices, then calculates amounts from rates, time, and billable expenses while excluding non-billable work. Invoice line items can be grouped by project, task, person, date, or other available breakdowns.
Set rates once, track approved work by project, and keep estimate assumptions tied to the invoice through Everhour's cost and billable rate controls.
