Is GST included in building quotes and invoices?

Consumer prices must comply with total-price rules, including applicable GST and unavoidable charges. Confirm the total payable and check the supplier's GST registration if GST is charged. A valid tax invoice has specific requirements; an ordinary invoice is not automatically a tax invoice. GST credits are not available for private or domestic purchases. Business, mixed-use and property-development arrangements need separate tax advice.
