Unless there is an express contract setting forth a lump-sum basis for compensation, it is an unfair and deceptive act or practice for a seller to fail to provide, upon specific request, one itemized billing, statement, or copy of a work order, which includes:
01.Labor Charges. Labor charges, designating the number of hours and the rate per hour; or designating the flat rate labor charge or job rate if such repairs or improvements are customarily done and billed on a flat rate labor charge or job rate price basis; or, when a minimum charge is imposed, designating that fact.02.Parts and Materials. Parts and materials, designating each item that is separately included in calculating the total billing, and designating whether such parts or materials are used or rebuilt.03.Other Charges. Miscellaneous charges, designating the reason for the charge and the basis for calculation of the charge.04.Unit Pricing. Alternatively, where the agreement sets forth a price per unit, then the number of units being billed at that price. For example, a contract provides for carpeting and installation at ten dollars ($10) per yard. The itemized billing would state "92 yards carpeting at $10 per yard equals $920."Idaho Admin.
