Okay
So this is what I found so far over different threads of this forum :
1) you can invoice your customers without having company registered.
2) you have to put that on income side in tax declaration .

Questions open :
1) Can you deduct costs of gaining income (eg.travel costs,hotel stay , PC) without having einzelfirma ?
2) Can I subcontract someone (outside of Switzerland) to execute activity while transfering costs to myself (salaried contractor engagment) ?
=====================
In Einzelfirma/GMbH case
1) Can I subcontract 3rd party company which is outside of my business scope to perform some activities (imagine IT company as general execution for entire infrastructure - which requires elektrical,other parties). Just example. Can 3rd that be from outside of CH ?
2) In einzelfirma win is direct salary of owner - in GMbH it's not - you pay yourself salary.
So can I have unsalaried person executing some work for me - eg. my wife - while actually she would not be working for me - just executing tasks - but these may involve travel and as such - can I put them on my books ?
Do I need permission from my employeer while I perform non salaried activities ?
Working for corporation - is competetive operation considered in scope of local branch office operations (eg. mainly financial investment company that doesn't sell anything but all thru partners) - while actually I perfrom educational services (it's competetive operations in scope of Corporation which is US based but not local Swiss office)?
Thanks in advance
