What are the correct sections to choose from OKVED?

Question

Electronics

The point is this. You need to create an individual entrepreneur with the following criteria:
1. STS 6%
2. Software and website development
3. Website promotion and support
4. Online store (radio components, auto electronics, auto parts, arduino and similar boards) with the possibility of selling personally and by mail (delivery services). This refers to several online stores.
Can it be combined into one IP or something will have to be removed?
Is the size of activities limited or not?
If, for example, you need to add another list of products to the online store, how to expand the list?

Answer 1

It is possible to combine into one IP.
Unfortunately I can't tell you the size.
In the list of OKVED codes, indicate software development as the main activity and trade as additional activities. In the list, it is better to immediately indicate all possible types of activities - in the future, making changes to the "statutory" process is not very fast and, again, not free.

Answer 2

I think these lists should be combined:
Programming;
Website promotion;
Internet trading;
Courier activity.
