Most Shopify stores don't have a profit problem — they have a visibility problem
One thing I found while running these numbers: even a seemingly small increase in shipping costs or refunds can completely change the story for a store's profitability. It's crazy how two stores with identical revenue can end up in totally different situations just because of these invisible line items.
Curious — which of these (refunds, shipping, fees, CAC) actually surprised you the most when you saw the real impact?
