Need advice regarding India Compliance app

Hi all.
I’m new to ERPNext and India Compliance app.
Have currently set up ERPNext in Frappe Cloud, along with the India Compliance app.

But before i fully delve into using these apps, i have a few queries that i could use some expert advise on:

  1. Is India Compliance app, in itself, sufficient to fulfill all the necessary Compliance/GST/IT related activities within ERPNext, without depending on any of the ERPNext’s existing modules?
  2. Does it fully encompass all the ‘Indian accounting’ compliance related activities that a company could need?
  3. Also, how well do customisations/integrations in ERPNext play with the India Compliance app? Does this app require any additional/special consideration when ERPNext customisations/integrations are implemented?
  4. Is ERPNext + Indian Compliance app, a 100% replacement for any other accounting system (Tally, Vyapar, Busy etc.)?

Thanks in advance.
