Regarding manage inventory store wise

[Ashish_k_php]

Is there possible separate inventory for the different stores from admin?

[Tom Robertshaw]

Inventory is a global level attribute in Magento 1 & 2 (for now) and so this is not possible. The way around it is either to have separate installations (that could be running on the same codebase deployed to a separate location with a different database) or through an extension. 

I don't have familiarity with any of them but there are a few around on Magento Connect:
