In many companies the monthly report is a fixed date in the diary, not as a decision but as work: exporting, copying together, formatting, distributing. By the time it is finished, the figures are already a week old.
Automated reporting reverses the order. Data comes together continuously, is checked against your plausibility rules and is ready before anyone asks for it. On top of that comes a short commentary: what has changed and what stands out.
The real gain is not the hour saved. It is that you see deviations while there is still time to act.
