# What Is Cash Flow?

> Cash flow is the net movement of money into and out of a business over a period — distinct from accounting profit because timing of receipts and payments differs from revenue recognition.

**Cash flow** is the net amount of cash moving into and out of a company during a period — the reality check behind P&L and ARR charts.

### How it works

Statements divide cash flow into three buckets:

- **Operating** — core business: customer collections minus payroll, vendors, and rent
- **Investing** — [capex](/glossary/capex), acquisitions, asset sales
- **Financing** — equity raises, debt draws, repayments, dividends

A startup can show growing revenue on accrual books while operating cash flow stays negative — common when enterprise customers pay net-60 or annual prepayments lag recognition. Conversely, a financing inflow boosts cash without improving operations.

Founders and boards watch **free cash flow** (operating cash minus capex) as a maturity metric. Early venture companies expect negative operating cash flow; the question is whether unit economics trend toward sustainability.

Bridge financings and tax refunds can temporarily inflate operating cash — investors reconcile "quality of cash flow" by stripping one-time items before comparing quarter-over-quarter trends.

### Why it matters

- **Founders:** Manage collections, payment terms, and hiring to cash, not just GAAP metrics. [Cash balance](/glossary/cash-balance) is the snapshot; cash flow explains the trajectory.
- **Investors:** Due diligence reconciles bank statements to reported burn. Surprises here kill deals faster than missed revenue targets.

### Common mistake

Using EBITDA or net income as a proxy for cash available to run the business. Working capital swings, deferred revenue, and capex can diverge sharply from profit — trust the cash statement.

## FAQ

### What is cash flow in simple terms?

Cash flow tracks actual money in and out — customer payments, payroll, rent, equipment — not just what your income statement says you earned on accrual accounting.

### Why does cash flow matter?

For founders, positive operating cash flow reduces fundraising dependence. For investors, persistent negative operating cash flow with weak unit economics signals future dilution or distress.
