How do plugins affect my subscription amount?

Activating a plugin will affect your subscription amount for your next billing cycle. The increase in amount depends on the following factors: 
-- Billing frequency - Annual or Monthly
-- Subscription price of the selected plugin
-- Number of stores in your environment
-- Number of licences purchased
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 a plugin AND not updating your Store / POS count. 
Once activated, you cannot deactivate the Multiple Units of Measure plugin because deactivating the plugin would affect the entire master data and all the transactions across the application leading to rounding off discrepancies.
Activating or Deactivating the following plugins will not affect your subscription amount for your next billing cycle because these plugins are free:
-- Elavon Payment Processor
-- Moneris Payment Processor
-- Clover Connect Payment Processor
-- Hospitality for Quick Serve and Fine Dining
The Hospitality for Quick Serve and Fine Dining plugin is by default included in both the editions - Community and Enterprise. This means that you will NOT be required to purchase and subscribe to this plugin. You just have to activate the plugin from the Purchase Subscription screen to unlock the hospitality features.
