When you add a user, you will be prompted to fill in their details. One of the fields they ask you is their user role.
So what is a role? A role is the permission level you give to your users, and it defines what they can and cannot do within the Saladplate account. Company admins can create and customize a role for your users of different functions at the "Roles & Permissions" section.
For example, you can set up a role to have the right to make purchases but not modify user rights within the company. You can select all the rights that you want to grant for this role.
You can edit a user's role at the "Company Structure" section in your account.
Just select the user you want to edit, it will appear as highlighted, then click "Edit Selected". Likewise, you can delete users here.
