Do not commit to the inventory, build, and warehouse spend until the funnel, cash, and margin all hold up against break-even. The model only works if early demand can support the fixed load before recurring revenue catches up.
1Demand Proof0.8% / $150Run a paid traffic test before the $250,000 Year 1 marketing budget, and confirm visitor-to-subscriber stays near 0.8%, CAC stays near $150, and retained subscribers hold near 70.0%.
2Supplier Terms$50K + $10KLock supplier terms before the $50,000 inventory seed and the $10,000 packaging die-cut spend, because weak terms trap cash before sales can refill it.
3Warehouse Load$10.9K/moValidate the warehouse need before the $5,000 rent and $25,000 racking spend, since fixed costs already run about $10.9K a month before payroll and marketing.
4Platform Stage$40KStage the platform work before the $40,000 customization and integration spend, and make sure the checkout, subscription flow, and member tools work before full rollout.
5Cash Cushion$805KBudget launch cash around the $805,000 minimum cash need in Month 2, so capex, marketing, and payroll do not outrun the first subscriber base.
6Launch Capacity79.5% CMWith year 1 mix and costs, contribution margin is about 79.5%, which puts base break-even near 289 active subscribers; hire customer service only when support volume proves it.
