I want to start a software company please help.

TL;DR: Have a finished software app with subscription. Need guidance from Indian founders on: 1) Essential docs/process to register a software company in India? 2) Can one company launch multiple future apps/products under its name? Seeking practical steps & common pitfalls.

This question may have been asked many times if so then can you please provide me link of that post?

Hello,

I've built my first software app (with website & subscription model) and now need to set up the company in India to launch it properly.

My goal is to structure it so the company (like Meta) can own this app (like Facebook) and potentially launch other products (like Instagram) in the future under the same company umbrella.

Could you please share insights on:

1. Registration Essentials: What's the basic process and paperwork needed to register a software company in India (Pvt Ltd, LLP, etc.)? What about initial requirements like GST or Startup India?
2. Multi-Product Structure: Can my single registered company legally launch multiple different apps/products over time, or is a new company needed for each major product?
3. Key Advice/Pitfalls: Any crucial tips or common mistakes to avoid during the company setup phase for a first-time tech founder in India?

Thanks!
