Use this checklist before you commit to production, packaging, hires, and paid growth. The go/no-go test is whether the shot line can hold $3.50 pricing, $0.40 unit COGS, and enough volume to cover about $338K in monthly break-even revenue without running cash past Month 14.
1Demand Proof100K unitsVerify first-year sell-through can reach 100,000 units across five flavors, or 20,000 each, before you buy inventory and lock ad spend.
2Price Check$3.50Test that buyers will clear the $3.50 unit price in the market, because a lower realized price cuts the room you have to cover fixed costs.
3Unit COGS$0.40Get written supplier quotes that hold total unit COGS near $0.40, including ingredients, bottle, cap, label, and co-packer fee.
4Inventory Run$40KDo not place the $40,000 initial inventory run until shelf life is proven, because stale stock turns working capital into dead cash.
5Fixed Load$338K/moKeep rent at or below $3,500 a month and total fixed overhead near $6.45K a month, or the break-even bar rises before the first case ships.
6Cash RunwayMonth 14Fund the $197K capex stack and $245K first-year payroll so cash lasts through Month 14, and delay the Month 13 sales hire and Month 25 service hire if sell-through slips.
