My companies in administration

A user with the administrator role can access the "administration" section of the menu, where he/she can create as many companies as he/she wishes. But what is the real purpose of the companies created?

Companies can be assigned to each work report template, in other words, each work report template is linked to a company. And the company data (logo, fiscal code, fiscal name, address, email) are automatically displayed in the PDF header of the work report
