What is Cash Flow?

Cash flow represents the net amount of cash and cash equivalents moving into and out of a business during a specific period. It is the lifeblood of any startup, and its management is often more critical for survival than the management of accounting profit. Cash flow is generally categorized into three main areas: operating activities (cash from day-to-day business operations), investing activities (cash used for buying or selling assets like equipment or intellectual property), and financing activities (cash from raising debt or equity, or paying dividends). A common challenge for startups is the "cash crunch," where a company may be profitable on its income statement but lacks the liquid cash to meet its immediate obligations, such as payroll or vendor payments. This often occurs due to a long "cash conversion cycle," where cash is tied up in inventory or slow-paying accounts receivable. Regularly forecasting cash flow allows founders to anticipate potential shortages and take proactive steps—such as securing a line of credit or accelerating collections—to ensure the business remains solvent. For investors, a startup's ability to generate positive cash flow over the long term is the ultimate measure of its viability and the sustainability of its business model. It is essential to distinguish between "Cash Flow" and "Profit," as they are recorded differently under accrual accounting.
