What do you mean by “run business logic rules over the calculations”? Genuine question.

Don’t most people embed business logic into their spreadsheet formulas?

Or is there something else you’re referring to?

It’s not uncommon for the sums of the spreadsheet to get fed into other systems or even spreadsheets.

There being validation around that can significantly reduce errors, such as checking totals against system values etc.
