None, really. It will just be consulting by a different name but focused on a particular business sector.

Typically they are the same, but for the sake of this graph, I would call consulting more of a management advisory function where you provide support on ambiguous transactions, sometimes yes or no decisions while advisory for a lot of these firms is simply an outsourced accounting function providing something like an internal audit function, 606 adoption, or some other specific accounting function that the Company cannot currently staff with their own employees.
