Generally speaking, there are more of these sayings:

Business has no boundaries, and you have the right way

Business has no boundaries

The meaning of the first two sentences It’s almost the same. It basically means that business has no boundaries or scope and is extremely flexible and malleable. Only by adhering to morality and integrity can we do business with integrity.

Micro-business has no boundaries

This sentence may be used in the emerging unique business model of "micro-business".

If the subject of the question is not engaged in micro-business activities, perhaps "business without boundaries" would be more appropriate.
