There can be ambiguity of "recettes" between being a) turnover or b) profits. You specify that it otherwise refers to earned income, so I reject possibility a).

Here, "flows" can be taken to be the total flows over some period, for example daily or weekly. But if the context is already understood according to what you specify, I think it will be understood that this refers to both the level of individual flows (each item contributing to periodic totals) as well as the general evolution in the trend.

By "évolués", then, I assume this is in part making reference to the volatile, or at least changing, nature of the number and size of these figures to be calculated. But the focus is, I think, less on the evolution of these flows per se, and more the fact that there are a bunch of different numbers rolling in from one day to the next, and that this system handles what changes over time. Which leads me to somewhat prefer adding "flows" which then directs the reader to think of both those individual flows and there sums over time periods which can be related to their volatility, or at least changing nature from one day to the next.
