Which of the following must be included on all repair invoices?

The correct response is that all repair invoices must include any five items from the established regulations outlined in section 14.05. This section typically specifies critical details that ensure transparency and accountability in automotive repair transactions. By requiring that multiple key elements be present on the invoice, the regulation aims to protect consumers and maintain professional standards in the industry.

Including specific information ensures that both the customer and the service provider have a clear record of the transaction. Essential items often included may encompass the date of service, parts used, labor performed, and total costs, among others. The ability to provide thorough documentation impacts consumer trust and reinforces the dealer's responsibility for the services rendered.

While aspects such as the date of service and the dealer's business license number are important to have for compliance and clarity, the requirement to include any five items from the specified list ensures broader coverage of necessary information deemed vital in the industry. The customer's email address, although useful for communication, is not a mandatory requirement on all repair invoices based on existing regulations.
