Hello, I am starting an event management company and I have put a good amount of money in that. But I don't want to spend much on software systems like buying Genuine Windows then again pay for photoshop then again if I needed something I have to pay again! Is there any way out? Like is there any Linux OS for small businesses? Recently I came to know that Linux is also a GUI-based OS and is free but can I use it for business? Also if there is any another Free OS then please let me know.
