Roles
A role represents a staff member's job, and contains all the granular permissions that a user requires to do that job. For example, the predefined Merchandiser store role grants the user access to your Shopify admin home, and all related store-level permissions in Products, Catalogs, and Content. You can assign the Merchandiser store role to users who update your products and collections.
You can create roles and assign roles to users to grant them permissions to different areas of your business from the Settings > Users > Roles page of your Shopify admin. You can assign multiple roles to a user, granting the user the accumulative permissions from all their assigned roles.
Each role has a category that is managed either by Shopify or by an eligible user, and a set of related permissions.
The role categories and respective permissions available to you depend on whether your store is part of an organization, on the Shopify Plus plan, and whether your have Point of Sale channel locations with a POS Pro subscription.
