Plugins in Tagrain are either Subscription Based or License Based. So the price that you pay for your plugins is based on the number of POS terminals that you have in your setup and the number of licences that you have acquired. 
There will be no change in your subscription amount in the current billing cycle if you are only deactivating the Stock Transfers and Inventory Tracking plugin AND not updating your Store / POS count.
