A business can turn a profit and still run low on cash

When a sale and its cash land in different years

The last lesson in this course opened one company's income statement and traced its revenue down through gross profit to operating income, one subtraction at a time. Every figure in that walk was an accrual number: revenue booked, a cost matched against it, a profit left over. None of it said anything about cash. A wholesaler, a software company, a contractor, any business that ships first and bills later, can build that same chain of subtractions correctly and still watch its bank balance move the opposite way from its profit line.

A company's income statement, balance sheet, and cash flow statement answer three different questions about one business: what it earned over a stretch of time, what it owns and owes on one day, and how much cash actually moved.¹ The first of those follows a rule called accrual accounting. Revenue is recorded once a business has done what it promised, not once it has been paid. Costs are matched to the same period as the revenue they helped produce, not to the day they were paid. The standard that defines the rule times every item the same way: recognized once it occurs, not once cash changes hands.²

Take a distributor that ships $200,000 of goods to a retail chain in March, invoiced on 60-day terms. The goods cost the distributor $140,000 to buy and warehouse. Both figures land on the income statement the moment the goods leave the dock: $200,000 of revenue, $140,000 of cost of goods sold matched against it, $60,000 of profit, all dated March. The invoice is not due until May, and the retailer pays on time. For two months, a $60,000 profit sits on the distributor's books before a dollar of the sale's cash exists anywhere.

A separate statement exists to keep score of gaps like that one: the statement of cash flows, which restarts from a company's accrual profit and walks it to the cash operations actually produced.³

The same gap, running the other way

Run the timing the other direction and a business spends the cash first. A small appliance maker spends $180,000 in March on parts and labor to build a batch of blenders for an order it has not shipped yet. None of that $180,000 touches the income statement in March. Accounting treats it as inventory, an asset. The future value the business is holding onto, the cash a sale will eventually bring, still belongs to it, because nothing has been sold yet. In May the retailer takes delivery and pays $500,000. Only then does the accounting catch up, all at once: $500,000 of revenue, $180,000 of cost of goods sold released from inventory, $320,000 of profit, every dollar of it dated May.

The cash left in March. The profit did not exist until May, and only because a sale happened by then. Push the shipping date to June and the profit moves with it. The cash already spent does not move at all.

Equipment runs the same delay out much further. A business that buys a $500,000 machine expected to last ten years does not expense the purchase the year it happens. It spreads the cost in equal charges of $50,000 a year, called depreciation, matched against the ten years of output the machine is expected to support.⁴ That is the same matching principle that separated the distributor's revenue from its cost. The cash left the business once, in full, the year the machine was bought. The income statement records a tenth of that cost that year, and a tenth again in each of the nine years after. That is a non-cash charge in the strict sense: it reduces reported profit without any cash leaving the business that period.⁵ Ten years is not a fact about the machine. It is the business's estimate of how long the machine will keep producing at a useful rate, made the year it is bought and rarely revisited until it is obviously wrong.

The account where the timing gaps pile up

The distributor's $60,000 of unbilled revenue sits in accounts receivable, an asset, until May's payment clears it. The appliance maker's $180,000 sat in inventory, also an asset, until the sale released it. A business's payables run the opposite way: money it owes suppliers for goods or services already received but not yet paid for, a liability rising instead of an asset falling. Add receivables and inventory. Subtract payables, and any other short-term obligation the business has already collected but not yet earned. The total is working capital: the cash tied up in the ordinary business of buying, making, and selling before any of it turns back into cash.⁶

Every business that runs on this accounting owes its cash flow statement the reverse of that arithmetic.³ Start at net income, add back the depreciation and other non-cash charges, then adjust for the cash the period's working capital tied up or released. One line sums it.⁷

The sign on each account follows one rule.⁸ A current asset that grew, receivables or inventory, ties up cash and gets subtracted. A current liability that grew, payables among them, frees cash and gets added back. Follow one business through a full year built from that rule. Net income was $500,000, plus $40,000 of depreciation added back like the appliance maker's machine. Three working-capital accounts moved the way growth moves them: receivables and inventory up, payables up too.

Profit for the year was $500,000. Cash from operations was $410,000, $90,000 less. Every dollar of the gap has an address: two accounts growing because the business is growing, one growing because its suppliers are, in effect, lending it money a little longer. None of the three is a problem by itself. A business scaling up sales on credit is supposed to see receivables grow faster than cash in hand, for as long as it keeps growing. The question worth asking is not whether the gap exists. It is whether the gap is closing or widening.

What a profit takes for granted that cash does not

Every dollar of profit in the examples above depended on a judgment about the future. The distributor had to judge that the retail chain would actually pay in May. The appliance maker had to judge that the blenders would actually ship. The equipment buyer had to judge that a machine would still be worth using in year nine. Change any of those judgments and the profit changes with it, even though not a single dollar has moved. Cash carries no such risk. It left the account or it came in; neither fact waits on an estimate. Some of a reported profit rests on a judgment still waiting to be proven right. The rest is cash that has already cleared.

Cash is not immune to management. A business can stretch its own payables, sell receivables to a factor, or delay a purchase it needs, and operating cash flow looks stronger the same quarter. What separates those moves from an aggressive revenue judgment is the counterparty: a lender, a factoring firm, a supplier who notices when payment starts coming later. A judgment about when a machine wears out, or when a sale is good enough to book, leaves no trail outside the company at all.

Three comparisons turn that asymmetry into something an investor can check, each with an exact address in a filing. First, compare the growth of accounts receivable to the growth of revenue, both between the same two year-ends. Receivables growing faster than revenue is the distributor's two-month gap, stretching. It always means reported revenue is running further ahead of its cash than it used to.

Second, compare cash from operations to net income across several years rather than one. A single year's gap, like the appliance maker's, is normal and closes on its own once the goods ship. A gap that keeps widening for three or four years running means growth is consuming cash rather than being funded by it.

Third, compare capital expenditure, in the investing section of the cash flow statement, to depreciation, in the operating section, over the same years. When a business spends consistently more on new equipment than it depreciates on the old, the ten-year estimate behind that charge is probably too generous, and reported profit is charging less wear than the business is actually creating.

One more lever sits inside the same three accounts and cuts the other way: margin. A review of a hypothetical $4 million professional-services firm found that raising its gross margin from 50 to 60 percent freed roughly $100,000 of cash at the same 90-day collection speed, without one invoice paid a day sooner.¹⁰ A widening gap between profit and cash is not always a collection problem. Sometimes it is a margin the business has not yet fixed.

None of these comparisons proves anything alone, and none replaces reading a company's own cash flow statement, line by line. What they give is a habit: ask whether the cash a company reports confirms the profit it reports, or only echoes the number at the bottom of the income statement.
