Seeking Client Friendly Inventory Tracking Plugin

I have a site that I would like to add a multi-client login to for each client to view their customized product(s), check inventory in real time, check shipping times, track shipping and replenish / re-order product.
Is there a plugin to in addition to an ecommerce solution that will allow this.
(with additional functionality such as email/text notifications of low inventory.. ect..)

Any help would be greatly appreciated.

Best,
