Before you scale ads, hires, or platform tools, verify that the catalog still clears break-even math. The model only works if order value, CAC, fees, repeat buys, and the $115.5K build stay close to plan while cash covers the Month 25 trough.
1Catalog Mix$136.40 AOVVerify the 50% premium template, 30% theme, and 20% setup mix still produce a blended order value near $136.40, because weaker setup attach cuts revenue per order.
2Demand Proof$45 CACTrack the Year 1 $45 CAC and the 12.0% repeat-customer rate; if either slips, the $120K marketing budget will not buy enough demand for break-even.
3Contribution80.5% CMLock marketplace commission, stock licensing, processing, and affiliate terms so contribution stays near 80.5% of sales; if fees rise, break-even moves out fast.
4Staffing Load$41.7K/moHold monthly fixed burn near $41.7K, which already includes one CEO, one developer, one designer, one support specialist, and one marketing manager, so add staff only when ticket volume proves it.
5Build Scope$115.5KKeep the one-time build and template library spend at $115.5K, and avoid long platform commitments, because those costs are sunk before operating break-even.
6Cash Cushion-$107KKeep enough cash for the $107K trough around Month 25, because break-even arrives in Month 26 and payback takes 43 months.
