By default, there are 4 profiles ready to use:
"Administrator": The highest rank. It has all the rights and can access everything on the PrestaShop installation.
"Logistician": Those in charge of packing and sending orders. Can only access the orders, shipping and stock management pages, and part of the catalog and customer pages.
"Translator": Those who are tasked with translating your shop's textual content. Can access products and categories, CMS (content management system) and the "Translations" page.
"Salesman": Your salespersons, if any. In addition to the translator's access rights, can also access the customer pages, the modules and web service, and some stats.
The "Administrator" profile cannot be deleted, only renamed.
To add a new profile, just click on "Add new profile".
Then enter a unique name, and save.
Once the profile has been created, you need to configure the access rights for the new profile.
