Key ideas in Business Mechanics and Investing
- Low gross margin leaves thin profit dollars to absorb sales and support overhead.
- High-touch sales models demand rich gross margins to support high commissions.
- Thin-margin businesses require low-cost, self-serve, or automated distribution.
- LTV measures long-term theoretical cash, while acquisition costs must be paid upfront.
- A payback period longer than existing cash reserves creates an acute liquidity crisis.
- Fast growth drains cash faster when payback cycles are extended.
- Negative contribution margin means every additional sale deepens total operating losses.
- High fixed operating leverage magnifies both profit surges and downside revenue drops.
- Fixed-cost leverage cannot cure losses on direct variable fulfillment expenses.
- Heavy fixed overhead cannot be cut quickly when top-line consumer demand collapses.
- Scaling volume with negative unit economics speeds up cash depletion.
- Inventory purchases drain cash well before goods can be manufactured and shipped.
- Selling goods on 60-day customer trade credit locks up capital in unpaid receivables.
- Surging sales force larger upfront cash outlays into inventory before revenue arrives.
