Cash Flow vs. Profit: Why Profitable Businesses Still Go Broke

Every year, genuinely profitable businesses fail. The mechanism is always the same: profit and cash are different quantities that move on different schedules, and payroll is due in cash.

How they diverge

• Receivables: you earned it, they haven't paid. Profit says yes; the bank account says not yet.
• Inventory and equipment: cash leaves now; the expense (via COGS or depreciation) hits the P&L later.
• Loans: receiving one is cash without profit; repaying principal is cash out with no expense.
• Owner draws: not an expense at all, but very much a cash outflow.
• Prepayments: a customer deposit is cash today, income when earned; annual software billing is cash today, expense all year.

Watch both, differently

The P&L answers 'is the model working?', read it monthly, watch margins and category trends. Cash flow answers 'do we survive the next sixty days?', watch money in versus money out per month, know what's due (bill aging), and know what's owed to you (open invoices).

The dangerous quadrant is profitable-but-cash-poor: growing businesses land there constantly, because growth eats cash, more receivables, more inventory, more people, all funded before revenue collects.

Practical guardrails

• Keep a cash buffer: the classic target is 2-3 months of expenses.
• Invoice immediately and chase politely; every day of receivable age is a day you're financing your customer.
• Watch bill aging so due dates never surprise you.
• Before big purchases, look at the monthly cash view, not the P&L, profit won't make payroll.
