Why Your Margin Looks High but You Still Lose Money
Learn the common reasons ecommerce brands report high margin but end up losing money after full cost allocation.

High margin does not guarantee healthy cash flow
A margin snapshot often ignores returns, failed deliveries, ad volatility, and transaction fees. Profit disappears when those costs accumulate.
Most common blind spots
Teams usually underestimate costs that scale with volume rather than fixed operations.
- Underestimated return and refund reserve
- Rising CPA after scaling campaigns
- Payment and platform fees not allocated per order
- Promotions reducing realized selling price
Fix with scenario discipline
Use base, conservative, and stress scenarios before spending more on traffic. If stress scenarios turn negative, fix operations first.
