A tax invoice
A GST-registered supplier may issue a tax invoice for a taxable supply when applicable. It generally identifies tax rates and amounts according to current requirements.
A bill of supply
A bill of supply is used in situations where tax is not charged under the applicable rules, including relevant non-taxable or composition scenarios.
Keep settings accurate
Do not collect GST simply because a tax template exists. Maintain the correct business profile and obtain professional advice for uncertain cases.
