Every SKU ranked by contribution margin after COGS, discounts and returns — not by revenue. The products that look like winners on a revenue chart are often the ones funding their own losses.
Revenue reports rank by what came in. This nets out COGS, per-order discounts allocated back to products, and returns — which routinely reverses the order. A product can be the top seller and the worst earner at the same time.
A screener status computed from margin and volume: Star is high margin and high volume, Bleeder is negative or thin margin at volume, Sleeper is good margin with volume you haven't pushed, Leak is where discounts or returns are eating an otherwise healthy product. The thresholds are shown, not hidden.
For margin, yes — and you can paste costs directly in rather than re-exporting. Products without a cost are excluded from margin figures and counted separately, never assumed to be free to make.
