how to set up provider accounts
 

Can someone tell me how to set up provider accounts for access to the admin area?

You mean fullfillment staff? Provider accounts are in the Pro version.

Yes fulfillment staff; other admin users that can work with the cart? How can I set that up?

Click on 'Users' and then 'Add new Administrator'.

Once You create fulfillment staff members; how can I add restricted access to like "edit templates, genteral setting, modules options and etc. so the admin user cannot make accidental modifications to areas in the cart that shouldnt have been changed?

If you log in as your new fullfillment staff account, you'll see that it is already limited.

is it possible to add other areas of the cart as inactive locations for certain fulfillment staff members or is that something extensive?
