Field notes
Caddie begins with a seller's inventory catalog, loaded by CSV or manual entry with fields such as card name, grade, price, stock count, and photos. During a Whatnot show, searches can be filtered by price and grade, then sent to a browser-source overlay in one of four card layouts. The page also describes Pro reporting for lost bidders, bid heat, revenue against acquisition cost, and buyer requests that went unanswered.
