What the Chart of Accounts Separates in a Financial Model

The chart of accounts is the structured list of every account used to record financial transactions, organized by category. The primary structural requirement for early stage companies is the separation of cost of goods sold from operating expenses. Cost of goods sold contains only the direct costs that vary with revenue: the costs a company would not incur if it produced no revenue. Operating expenses contain all other costs. A chart of accounts that does not make this separation cannot produce a meaningful gross margin figure, and gross margin is the metric most commonly used by investors to evaluate the scalability of a business model.

A chart of accounts built correctly at inception requires no structural changes as the company grows. One built without this separation typically requires a full reconstruction before any institutional investor process, because the management accounts derived from it cannot be restated without rebuilding the underlying records.
