Itemised bills
Under the ACL, a consumer can ask you for an itemised bill that shows how the price was calculated. This request must be made within 30 days of whichever happens later:
> the services are supplied, or
> the consumer receives a bill or account from you for the supply of the services.
You must give the consumer the itemised bill, without charge, within seven days of the request. The itemised bill must be expressed in plain language, legible and clear.
