DTC brands waste money because marketing, finance, and supply chain optimize different metrics. One number fixes it: contribution margin per product. When all three teams use the same SKU-level CM figure, they stop chasing growth and start chasing profit.

Marketing, finance, supply chain should all be obsessed with the same number. Are they? Most DTC brands have three teams optimizing three different metrics. That's why growth creates chaos instead of profit. And here's how contribution margins connects everyone. Marketing needs CM to know what to push. If product A has 25% of CM and product B has 12% CM, which one should get ad spend? Obviously A. But if marketing only sees gross margin, they might push the wrong product. Finance owns this number. They should calculate CM by SKU and share it with every team. If finance isn't tracking cm, nobody's making informed decision. Supply chain uses CM for inventory decisions. Which products get priority when cash is tight? The ones with highest contribution margin. Which ones do you let prior stock up? The low CM once you're barely making money on. When all three teams see the same number, decisions align. Marketing pushes profitable products, finance tracks real margin and supply chain prioritizes cash generating inventory. That's the flywheel. One number three teams align. Now ask your finance person, do we have a contribution margin by sku? If not, that's the project tag. Your marketing and your finance needs. They need to see this.
