Sales statistics

Something that I'm surprised hasn't some up much in discussions is sales statistics. This, in my opinion is quite important for stores in order to easily see which items are sold the most, when they have been sold, and where they were sold to. Perhaps even sales history for specific items.

At the latest store we've built , we've used views to assemble which items sell the most, what brands sell the most, as well as sales figures (total sales, total shipping costs etc). It would however, be very useful to have a module pack that offers this. From our experience, views isn't always enough for this, so some code would have to be written. The functionality of this would most likely be usable for most Commerce sites, since orders and customer profiles are core features so I definitely see a value in making this shareable.

I know that analytics offers some of this functionality (through Commerce Analytics, which we also use on aforementioned site) but since it's a one way street communication-wise, It often doesn't reflect true store values. Canceled orders or returned items are not taken into account for example.

What do you guys think?
