Keep a detailed tracking sheet for everything - break-even math, category performance, ad spend versus return, logged weekly since day one. The platform's dashboard gives enough raw numbers to actually build something meaningful on top of it, which matters to me more than most people probably care about. Store and fulfillment side has never had a single issue, so the only variables i'm managing are the ones i actually want to be digging into. Review collected by and hosted on G2.com.

Wish the native reporting matched the depth i build manually. Category breakdowns, seasonal trends, per-product margin after ad spend - all things i track myself because the dashboard doesn't surface them out of the box. Would save real time if even half of my spreadsheet was built in. Review collected by and hosted on G2.com.
