Definition
Cash flow is the net amount of cash moving into and out of a business during a specific period. Positive cash flow means more money is coming in than going out. Negative cash flow means the opposite.
There are three types:
- Operating cash flow: Cash generated from normal business operations — selling products, paying employees, collecting from customers.
- Investing cash flow: Cash spent on or received from long-term assets — equipment purchases, software investments.
- Financing cash flow: Cash from or to investors and lenders — raising capital, repaying loans, paying dividends.
Cash Flow vs. Profit
This is the distinction that trips up most business owners. Your P&L might show a $50K profit this month, but your bank account dropped by $20K. How? Because profit is an accounting concept that includes non-cash items and timing differences. A $100K invoice sent today counts as revenue — but the cash might not arrive for 60 days.
82% of businesses that fail cite cash flow mismanagement as the primary cause. Not lack of revenue. Not bad products. Cash flow.
Example
A consulting firm bills $200K in January. Their P&L shows $200K revenue minus $140K in expenses = $60K profit. But two clients on Net 60 terms owe $120K that won't arrive until March. Meanwhile, payroll of $90K, rent of $15K, and software subscriptions of $10K are all due this month. Actual cash in: $80K. Cash out: $115K. Net cash flow: negative $35K — despite being “profitable.” This is why AR management and payment terms directly determine whether profit translates to survival.
What to Watch For
- Seasonal gaps: Many businesses have predictable slow months. Map your cash flow cycle over the past 12 months and build a reserve for the troughs. A business that averages positive cash flow but goes negative every Q1 can still fail in February.
- Growth-driven cash crunches: Rapid growth often consumes cash because you pay for hiring, inventory, and infrastructure before the new revenue shows up. A company doubling revenue can easily run out of cash. Track your burn rate and runway alongside growth metrics.
- Confusing cash flow with revenue: Revenue is recognized when earned. Cash flow is recognized when the money actually hits your account. The gap between those two is where businesses die.
