The first things they check
Within 60 seconds of opening your P&L, investors are looking at revenue growth rate, gross margin, and operating margin trajectory. These three numbers tell them most of what they need to know about the business model. If all three look reasonable, they dig deeper. If any is off, they start probing.
Revenue growth gets benchmarked against stage expectations. A seed-stage company at 100% growth is normal. A Series B company at 100% growth is impressive. A mature company at 100% growth is either exceptional or unsustainable. Context matters, and investors have that context.
Gross margin tells them about the business model. High gross margins signal software, marketplaces, or premium products. Low margins signal services, commodities, or inefficient operations. The margin level constrains what else is possible - a low-margin business has less room for growth investment.
The balance sheet signals
Cash position is the first balance sheet check. How much cash, how much runway at current burn, any restricted balances. This sets the urgency of the fundraise and the leverage in negotiations. A company with 24 months runway negotiates differently from one with 6 months.
AR aging gets examined next. Is AR growing faster than revenue? Is it aging? Is it concentrated in a few customers? These questions reveal collection discipline, customer quality, and potential revenue quality issues.
Deferred revenue trends matter for subscription businesses. Growing deferred revenue means growing commitments to future service. Declining deferred revenue means either churn or shift to shorter contracts. The trend often predicts near-term revenue performance.
The expense scrutiny
Investors model what a reasonable expense structure looks like for your stage and business type. They compare yours to that benchmark. Headcount-heavy businesses get scrutinized for productivity per employee. Marketing-heavy businesses get scrutinized for CAC efficiency.
Specific expense patterns draw attention. Rapid growth in any expense category that outpaces revenue. G&A growing linearly with headcount (should scale sublinearly). Professional fees that do not have obvious projects behind them. Travel and entertainment as a percentage of revenue.
They also look for missing expenses. A company claiming high gross margin with no hosting costs, no customer support costs, or no payment processing fees might be misclassifying COGS as OpEx. This inflates gross margin but is easy to catch. The cleanup often moves gross margin down 5-10 points.
What signals quality
Consistency across periods. Revenue categorization that is the same in January and December. Expense line items that stay in the same account all year. No unexplained reclassifications. This signals operational discipline.
Clean tie between P&L and bank statements. Revenue on the P&L should reconcile to deposits. Expenses should reconcile to outflows. When investors can trace from financial statements back to source, they trust the numbers. When they cannot, trust erodes.
Documentation of anything unusual. Large one-time items with explanations. Revenue recognition policies documented. Expense classification decisions defensible. Investors are looking for a financial operation that has been run thoughtfully, not one that has been improvised. Documentation is the signal.
