The purpose of legally stipulating the duty to provide an itemised account is to enable the consumer to assess whether the sum of money demanded for a service for which no price has been agreed upon is reasonable. The consumer must be in a position to check the prices stated for the goods and services that form part of the product.
The DCO holds the opinion that to demand payment for an invoice is clearly in breach of the principles of good marketing practises when the consumer is entitled to receive an invoice by law.
Please note that 9 statutory orders concerning invoicing are still in force; see the introduction to price information.
