What should I consider before starting an online business?

Can you please give me pointer on what I should consider before starting an online business.

Hello Vijender

You might have better luck with answers if you explain what it is you are actually trying to do?

Your question is too vague and broad and needs to be more specific - like, "What is a good software to start building code?" - as an example

BTW - I know nothing about IT

That's a very broad question. Maybe you could be a little more specific with an aspect of starting a business (like raising money, for example).

Here are some questions here on Bright Journey:

• What should I consider before jumping from stable job to startup?
• How relevant is business plan/business model before starting up?
  
• Should I work for a startup before starting my own?

There is a ton of knowledge here on this site, do search or browse the topics.
