The business health score is a letter grade summarising four areas of a business. A weak score in one area lowers the overall grade even when the others are strong.
Survival
Whether the business can pay its bills. Draws on cash balance, burn rate, cash runway, and money owed to you.
Stability
Whether income is reliable. Draws on how concentrated revenue is among a few customers, and how promptly those customers pay.
Efficiency
Whether costs are controlled. Draws on profit margin and the share of revenue going to operating expenses.
Growth
Whether revenue, customer count, and sales are increasing over time.
Interpretation
The grade indicates which of the four areas to examine first. It does not, on its own, identify a cause.
