Add-ons help the customers to add features that are unavailable in their plan but 
are required as and when the need arises. Add-ons have additional charges apart 
from monthly recurring.  
For e.g., you have subscribed for the Bronze plan and you want the Call Scribe 
feature, then you can use this feature as an add-on.  
Check Pricing page for more details. 
Hope this helps!
