That term is too vague and maybe all encompassing. It could be good management skills. It could be good people skills. Being able to control your cost. 😕
business skills, in my opinion, is a combination of the following:
charisma, management + MARKETING savvy-ness, good time management (efficient + productive), and a basic understanding of economics and how it relates to small business.
I would say if you have the skills mentioned above, then you've got a nice collection of "business skills."
jb, thanks for sharing. If I had to guess I would have said time and resource (people) management, and marketing skills. Those and the others you mention I see as a general "resourcefulness" required in a good business person.
