Difference between Standard Plan and Government GSTN Plan

Difference between Standard Plan and Government GSTN Plan

Hello,

This question is related to Indian Users as Zoho provides a special GSTN plan for small businesses for free in co-ordination with Indian Government. 

I would like to know what are actual differences in features in the Standard Plan (₹749 /org /month billed annually at this moment) and the GSTN plan provided for free by Zoho for <1.5CR turnover companies.

I know of following features which are available in GSTN plan which are not in Standard plan:
  1. Recurring Invoice           

  2. Recurring Bills           

  3. Recurring Expense           

  4. Payment Reminder    

  5. Time Tracking module
  6. Customer Support - Email & Voice
Cons:
  1. Not able to use addons
I would like to know what possible features I might be missing if I go with GSTN plan rather than the paid Standard plan unless my turnover is going beyond 1.5Cr. So far I see actually there are more features provided in free GSTN plan which are actually not available in Standard plan. What other features I am going to be missing out?
