Use the table below to choose the narrower corporate-finance branch before applying a term to a model, board memo, financing analysis, transaction review, or risk assessment. Move into the term page when the evidence source, calculation, agreement, filing, account, or governance right matters.

What to Check

  • Cash-flow statement line, operating metric, revenue source, expense category, or margin measure.
  • Timing of cash collection, payment, capex, working capital, taxes, and debt service.
  • Reported financial statements, management accounts, contracts, invoices, budgets, or KPI definitions.
  • Recurring versus one-time items, accrual versus cash treatment, and segment or unit-economics basis.
  • Effect on liquidity, valuation, profitability, debt capacity, and operating runway.

Common Mistakes

  • Treating revenue, earnings, operating cash flow, and free cash flow as interchangeable.
  • Ignoring working-capital timing and capital expenditure needs.
  • Comparing margins without matching accounting policy and business model.
  • Using one period of cash flow without checking seasonality and nonrecurring items.

Corporate cash-flow content is educational and does not provide accounting, audit, tax, valuation, or investment advice.
