Actually, the question has arisen, and what license is needed for the work of a small company that develops application software (applications running on Win32). In addition to the license to carry out trading activities.
Read Federal Law of 8 August 2001 N 128- “On Licensing of Certain Types of Activities” (as amended up to March 13, 21, December 9, 2002, January 10, February 27, March 11, March 26, December 23, 2003 , 2 November 2004, 21 March, 2 July, 31 December 2005, 27 July, 4, 29 December 2006, 5 February, 19 July, 4, 8 November, 1, 6 December 2007, 4 May 2008) ')
I did not find mention of software development there. Maybe it is not necessary then any licenses or am I mistaken?
PS: If the design is wrong, then correct me, I will definitely fix it.
