Which expenses are fixed and which move with sales for an EL wire retailer?

What should you verify before you commit to inventory, storage, and hiring?
Founder checklist
Test traffic, basket mix, and monthly burn before you place the first big buy. If conversion stays near 2.0% and the basket holds near $61.60, the Month 38 break-even path is real; if not, cash gets tight fast.
1Traffic Proof2.0% / $61.60
Track whether visitors convert at the Year 1 2.0% rate and the basket lands near $61.60, because break-even depends on paid orders, not traffic alone.
2Monthly Burn$14.3K/mo
Make sure the business can carry about $14.3K of monthly fixed cost in Year 1, or the path to Month 38 break-even gets too steep.
3Basket Mix40/30/20/10
Confirm orders really split near 40% starter kits, 30% spools, 20% power inverters, and 10% glow accessories, because the basket math only works if the mix holds.
4Supplier Timing$25K buy
Lock supplier timing before the first $25,000 bulk stock buy, so launch demand does not turn into stockouts or tied-up cash.
5Packing Flow2.2 units/order
Test packing at the Year 1 pace of 2.2 units per order before peak season, because slow picks and packing raise shipping errors and labor strain.
6Cash RunwayMonth 38 / $375K
Keep runway through Month 38 and the $375,000 minimum cash point at Month 40, since EBITDA stays negative in Years 1 through 3.
