Ehsan's Analysis
E-commerce burn rate analysis needs to separate two types of spend: inventory investment (which becomes revenue) and operating burn (which does not). A DTC brand burning $500K/month might have $350K in inventory purchases that will generate $700K in revenue next month — their real operating burn is $150K. VCs who funded DTC brands in 2019-2021 often conflated the two, leading to catastrophic misvaluations. The honest e-commerce burn metric is "cash conversion cycle" — the number of days between paying for inventory and collecting cash from the sale. Amazon's CCC is negative (they collect before they pay suppliers), which is why they can scale infinitely. Most DTC brands have CCC of 60-120 days, meaning they fund 2-4 months of inventory on their balance sheet. Reducing CCC from 90 to 45 days literally halves your working capital requirement — more impactful than any marketing optimization.
