Profit Leakage in Multi-Channel Businesses

Leakage one: return rate variance not reflected in channel economics. Different channels generate systematically different return rates COD-heavy marketplace channels at 20 to 25%, prepaid D2C website channels at 10 to 14%. If the unit economics model uses a blended return rate, it overvalues the high-return channels and undervalues the low-return ones. Leakage two: unrecovered marketplace settlement discrepancies. At ₹50 lakh GMV across three marketplaces, unrecovered discrepancies at 2% of GMV represent ₹1 lakh per month absent from the P&L, not attributable to any single channel, and invisible without reconciliation.Leakage three: channel-specific marketing attribution errors. When marketing spend across multiple channels is attributed to a blended CAC, the channels with strong organic performance subsidise the channels with weak organic performance misleading the investment allocation toward the subsidised channels. Leakage four: inventory holding cost misattribution. Inventory held specifically for a channel's minimum stock requirements (Amazon FBA minimum inventory, marketplace promotional stock reservations) generates carrying cost that should be attributed to that channel's economics but is typically absorbed into the general inventory cost. Leakage five: channel-specific customer service cost. Some channels particularly COD-heavy marketplace channels and offline distribution channels generate disproportionate customer service load relative to their revenue contribution. Leakage six: payment gateway variance by channel. Payment method mix varies by channel, and the payment gateway cost varies by method a difference of up to 2.5 percentage points between UPI and credit card. Channel economics calculated on a blended gateway rate are systematically incorrect for channels with extreme payment method distributions.
