We will show how the accounting system revealed a significant increase in the overheads linked to the new economic model and how this triggered the emergence of a new figure, the paying customer, whose income was to be captured. Accounting played a decisive role in the transformation by showing the costs of the draining policy. This revelation led the Crédit Lyonnais to draw away from the Saint-Simonian doctrine.
