What information is usually not required on a smog station's invoice?

The name of the inspection authority is typically not required on a smog station's invoice because the focus of the invoice is primarily on the transaction details related to the service provided, such as the costs and the services rendered. On an invoice, customers usually expect to see information that directly relates to their specific service transaction, like the materials cost, the completion time, and any diagnoses made during the inspection.

Including details about the inspection authority's name is generally not essential for the customer's understanding or record-keeping purposes. Instead, the invoice serves to document the costs and the work performed, ensuring transparency in the transaction, while the authority's name may be noted elsewhere, such as on official inspection reports or certificates rather than the invoice itself.
