High top-line revenue is a vanity metric if it doesn't translate to profit. By setting a high margin target (e.g., 80%+) and enforcing it through pricing and cost management, you ensure the business is sane and profitable, not just busy.

Official financial segments often reflect bureaucracy, not true business economics. By creating a 'Shadow P&L' through deductive analysis, investors can uncover massive hidden costs in non-core initiatives, as ValueAct did with Microsoft's hardware divisions.

Many founders run "too lean," maximizing short-term profit at the expense of long-term growth. Strategically investing in a team, even if it lowers margins temporarily, frees the founder to focus on scaling, leading to greater overall profitability and less burnout.

Entrepreneurs often assume the product generating the most revenue is the most valuable. However, when factoring in the time and energy required for delivery (return on time), that "bestseller" might actually be the least profitable per hour, making it a poor candidate for scaling.

At a small company, one or two big deals can significantly inflate the average productivity per rep. This hides the fact that the majority of the team may be underperforming. As the team grows and these outliers have less impact, the true, often flatlining, productivity of the sales force is exposed.

Escape the trap of chasing top-line revenue. Instead, make contribution margin (revenue minus COGS, ad spend, and discounts) your primary success metric. This provides a truer picture of business health and aligns the entire organization around profitable, sustainable growth rather than vanity metrics.

Use gross margin as a quick filter for a new business idea. A low margin often indicates a lack of differentiation or true value-add. If a customer won't pay a premium, it suggests they have alternatives and you're competing in a commoditized space, facing inevitable margin compression.

Beyond outright fraud, startups often misrepresent financial health in subtle ways. Common examples include classifying trial revenue as ARR or recognizing contracts that have "out for convenience" clauses. These gray-area distinctions can drastically inflate a company's perceived stability and mislead investors.

A potential buyer's first move is often to fire the least profitable clients. Proactively dropping these clients—those on legacy deals or who complain excessively—improves your gross margin, making the business more attractive and valuable before a sale even begins.
