Working Capital: Can You Pay Your Bills?

Here's a scenario that bankrupts profitable businesses: you have $200,000 in outstanding invoices (accounts receivable), $80,000 in inventory, and $15,000 in cash. Your payroll of $45,000 is due Friday. On paper, you're asset-rich. In reality, you can't make payroll because your assets aren't liquid. This is a working capital crisis, and it's more common than most entrepreneurs realize.

Working capital is current assets minus current liabilities — everything you own that can be converted to cash within a year, minus everything you owe within a year. Positive working capital means you can cover short-term obligations. Negative working capital means you're dependent on future revenue or external financing to stay operational.

Current Ratio: The Quick Health Check

The current ratio divides current assets by current liabilities. A ratio of 2.0 means you have twice as much in short-term assets as you owe in short-term obligations. Generally, a current ratio between 1.5 and 3.0 is considered healthy. Below 1.0 is a red flag — you owe more than you have available to pay.

But the current ratio has a blind spot: it treats all current assets equally. Cash in the bank and inventory sitting in a warehouse are both "current assets," but one pays bills today and the other needs to be sold first. That's where the quick ratio comes in.

Quick Ratio: The Honest Version

The quick ratio strips out inventory and other less-liquid assets, leaving only cash, accounts receivable, and short-term investments. This gives a more conservative picture of your ability to meet obligations without relying on selling inventory. A quick ratio above 1.0 means you can cover current liabilities without selling a single unit of inventory — a much stronger position.

For service businesses with little or no inventory, the current ratio and quick ratio will be nearly identical. For product businesses carrying significant inventory, the gap between these two numbers reveals how dependent you are on moving product to stay solvent.

When Growth Eats Working Capital

Counterintuitively, rapid growth is one of the most common causes of working capital crises. You need to buy more inventory, hire more people, and spend more on marketing before the revenue from those investments arrives. Each growth surge consumes cash that hasn't been replenished yet. Businesses with 60-90 day payment terms from customers are especially vulnerable — they've delivered the product but won't see the cash for months.

Managing working capital during growth means negotiating better payment terms with suppliers, collecting receivables faster, maintaining a credit line for bridging gaps, and resisting the temptation to invest every dollar of profit back into growth without maintaining adequate reserves.
