CM1 vs CM2 vs CM3

The CM1 vs CM2 vs CM3 framework is how DTC and Shopify Plus finance teams measure profitability at successive depths instead of relying on a single blended gross margin. The CM1 and CM2 meaning is the starting point: CM1 (Contribution Margin 1) equals net revenue minus cost of goods sold, payment processing, and fulfillment, so it answers whether a product is profitable to ship at all. CM2 (Contribution Margin 2) then subtracts the variable marketing and advertising cost allocated to that order, which reveals whether growth is actually profitable after customer acquisition cost, not just whether the unit economics work in a vacuum. CM3 (Contribution Margin 3) goes one layer deeper and subtracts an allocation of semi-fixed operating overhead such as software subscriptions, warehouse rent, and team salaries, landing close to a fully-loaded operating profit per order. The reason the CM1 vs CM2 vs CM3 distinction matters is that a brand can post a healthy 55 percent gross margin and a positive CM1 while running a negative CM2, because a 35 dollar CAC on a 70 dollar order erases the contribution once acquisition spend is counted. Most reporting tools surface gross margin or, at best, CM1, and leave the margin-destroying orders invisible until month-end. Agentis enforces the floor against whichever contribution layer the operator chooses, evaluating live COGS, freight, and FX at checkout so that an order which would look GAAP-profitable at the gross-margin line but destructive at the CM2 line can be blocked or adjusted before it confirms. For operators scaling past 10 million dollars in GMV, instrumenting CM1, CM2, and CM3 weekly and enforcing a CM2 or CM3 floor at the point of sale is what separates sustainable growth from cash-burning revenue.
