There is a large precedent of people writing financial reports and projects so I would look at accounting literature or talk to an accountant (possibly in a non-professional relationship) or business analyst about it before talking to a UX person.

I think I'd like to see an overview calculation at the top (which I think I see) and then see it broken down hierarchically below. I think that might be what you are trying to do, but it doesn't come across clearly.

Another issue is that this is described as a revenue report but I see stuff in there about salaries, desk costs, etc. which is not revenue but expenses. A real financial report would probably consider both and should be completely clear about what is what.
