A balance sheet is the financial statement showing a business's assets, liabilities, and owner's equity at a specific point in time. It always balances: Assets = Liabilities + Equity. Lenders use it to assess solvency, capital structure, and collateral.
The balance sheet is organized into three sections. Assets (left side or top): what the business owns, ordered by liquidity — Current Assets (cash, AR, inventory, prepaid expenses — expected to convert within 12 months) then Non-Current Assets (PP&E, intangibles, long-term investments). Liabilities (right side or middle): what the business owes — Current Liabilities (accounts payable, accrued expenses, current portion of long-term debt — due within 12 months) then Long-Term Liabilities (term loans, mortgages, lease obligations due beyond 12 months). Equity (right side or bottom): the residual — owner's equity or retained earnings. The fundamental accounting equation — Assets = Liabilities + Equity — must always hold. This 'balances' the sheet: if you add an asset (take out a loan to buy equipment), you also add a liability (the loan) and an asset (the equipment), keeping the equation balanced. Lenders derive critical metrics from the balance sheet: Current Ratio (Current Assets / Current Liabilities — measures short-term liquidity, target ≥1.5x-2x); Quick Ratio ((Cash + AR) / Current Liabilities — tighter liquidity test); Debt-to-Equity Ratio (Total Debt / Equity — leverage measure); Working Capital (Current Assets - Current Liabilities — the short-term operating cushion). Unlike the P&L (which covers a period), the balance sheet is a snapshot at a specific date — year-end, quarter-end, or month-end. Comparing balance sheets over time reveals whether the business is accumulating assets and equity or taking on more debt than it can support.
Every transaction affects both sides of the equation equally — Assets = Liabilities + Equity always remains true. Borrow $100K: cash increases $100K (asset), loan increases $100K (liability) — balanced. Buy $50K equipment with cash: equipment increases $50K, cash decreases $50K — total assets unchanged, balanced. If the equation doesn't balance, there's an accounting error.
Working capital = Current Assets minus Current Liabilities. It represents the short-term operating liquidity cushion — the buffer available to fund day-to-day operations, pay suppliers, and cover short-term obligations. Lenders require positive working capital as a basic solvency condition. Working capital loans (lines of credit) are specifically designed to supplement this cushion.
At minimum annually, typically at fiscal year-end for tax and lender reporting. Businesses seeking credit should have quarterly or monthly balance sheets. Loan applications typically require the most recent year-end balance sheet plus a current interim balance sheet dated within 90-120 days of the application. Most accounting software generates balance sheets automatically.
