Margin Leakage

Margin leakage describes the slow bleed of profitability that occurs when small, individually insignificant cost overruns affect a large volume of orders. Unlike a dramatic margin collision on a single order, margin leakage manifests as $0.50 here, $1.20 there: a slightly outdated COGS figure, a payment processing fee increase that was not reflected in pricing, a packaging material cost bump, or a carrier surcharge that went unnoticed. At 10,000 orders per month, even $1.00 of average leakage per order equals $120,000 annually in lost profit. The challenge with margin leakage is visibility: it rarely triggers alerts because each individual instance falls within acceptable variance. Detection requires comparing expected margin (based on pricing models) against actual margin (based on realized costs) at the order level across time. This comparison reveals systematic patterns: specific SKUs, freight zones, or promotion types that consistently underperform margin expectations.
