Should we do a Six Sigma for shipping and inventory? I also track via excel, but I have separate worksheets for item categories -- one for suits, one for shirts, one for shoes, etc. The reason is the measuring systems are all off, and I track measurements right on the item row. I have one column for s (sold) t (traded) k (keeping) or n (not yet sold). I have a color code system for whether things are listed or not, and separate columns for what the item cost, what it sold for with shipping, what shipping cost, what the ebay and paypal fees are, etc. I then have a page where all that gets consolidated to a single view across all worksheets, from a numeric perspective. Someday when I get really fancy, I will do a pivot table to see average selling price by brand label, etc. Have any of you bought something on ebay and NOT brought it immediately to the tailor? How inefficient from a market perspective to incur the dry cleaning costs twice for essentially just a miiddleman transaction. Or a freezer. I got one free from my aunt, but it didn't work. When I finally get another, all items will spend 4 days in the deep freeze before ever even being categorized, measured and logged. Problem solved.
