Here is something that surprises a lot of people the first time they hear it. A company can report growing profit year after year and still run out of money and fail. It sounds like a contradiction. If you are making money, how do you go broke?
The answer is that profit and cash are not the same thing. A company can earn a profit on paper long before the cash actually shows up, and sometimes the cash never shows up fast enough. If you only watch the profit line, you can miss the moment a business is quietly running dry.
Why profit and cash drift apart
Most companies record their numbers using accrual accounting. The key idea is simple. Accrual accounting counts revenue when you earn it, not when the cash lands in your bank account.
Say a customer buys a TV from you and pays with a credit card. Under accrual accounting, you record the sale as revenue the moment it happens. Your income statement shows the profit right away. But the cash is not in your account yet. It sits in Accounts Receivable until the payment clears. So on paper you are more profitable today, even though you have not been paid.
That gap between "earned" and "received" is where profit and cash start to drift apart. And that gap has to live somewhere.
The gap lives in working capital
The place it lives is working capital, and it shows up in three main spots. Each one is just a timing difference between when the profit is recorded and when the cash moves.
You made the sale and booked the revenue, but the customer has not paid yet. Profit is ahead, cash is behind. Companies usually collect their receivables in something like 40 to 50 days, so that is 40 to 50 days where the profit is real but the cash is still out there.
When you buy inventory, you spend cash right away, but you do not record any expense yet. The cost only hits your income statement when you actually sell the item. So a company can pour cash into stock sitting in a warehouse while its profit looks untouched. The cash is gone, the expense has not shown up.
Sometimes a customer pays you up front for something you will deliver later, like an annual software subscription. You have the cash in hand, but you are not allowed to call it revenue until you actually provide the service. Cash is ahead, profit is behind.
Put those three together and you can see why the profit line and the cash line rarely match in any given period. One is always leading or lagging the other, depending on which pocket the money is sitting in.
Negative working capital is not always a bad sign
Because of how these pockets work, you sometimes hear that negative working capital means a company is in trouble. That is not always true, and knowing the difference is a sign you actually understand the business rather than just the formula.
Some companies run on negative working capital on purpose, and it is a strength. A subscription company collects a full year of cash up front and delivers the service over the following twelve months. A retailer or a restaurant gets paid the instant a customer checks out, but pays its own suppliers weeks later. In both cases the company is running on its customers' cash. That is not a warning sign. It is an efficient machine.
The lesson is that the same number can mean opposite things depending on the business model. You have to look at where the cash and the timing are actually coming from before you decide whether it is good or bad.
The extreme case: good profit, empty bank account
Now push this all the way. It is possible for a company to look healthy on its profit measures for years and still go bankrupt.
Take EBITDA, a popular measure of profit that strips out interest, taxes, and the cost of long-term assets. A company can post positive EBITDA every year for a decade and still fail. How? EBITDA ignores several things that eat real cash. It leaves out the money spent building factories and equipment. It leaves out interest payments on debt. It leaves out one-time hits like a big lawsuit. A company can be "profitable" by this measure while it burns through cash on all three, and one day it simply cannot pay what it owes.
This is the answer to the puzzle we started with. The profit numbers were never lying, exactly. They were just never the whole story. Cash was the part that mattered, and cash was the part nobody was watching.
Why this is at the heart of FP&A
This is why one of the core jobs in financial planning and analysis is not forecasting profit. It is forecasting cash. And forecasting cash means forecasting the timing, working out not just how much a company will earn but when that profit turns into money in the bank, and when it does not.
A forecast that only looks at the income statement will miss the working capital gap entirely. It will show a company that looks fine right up until the point it cannot make payroll. Getting the timing right, seeing where cash gets tied up in Accounts Receivable and Inventory, and where it comes in early through Deferred Revenue, is often the difference between a forecast that holds up and one that misses the thing that actually matters.
Profit tells you whether the business model works. Cash tells you whether the company survives the year.
