Example Concept: Key financial metrics for small businesses include revenue, gross profit margin, net profit margin, cash flow, accounts receivable turnover, and current ratio. Revenue measures total income from sales, while gross and net profit margins indicate profitability after costs and expenses. Cash flow tracks the inflow and outflow of money, ensuring liquidity. Accounts receivable turnover assesses how efficiently a business collects debts, and the current ratio evaluates the ability to cover short-term liabilities with current assets.
