Profitable but Broke: Your P&L Isn't Telling You the Whole Story

Ever looked at your profit & loss report, saw a good result, then checked your bank account and thought, "Where's the money?" You're not going mad, and you're not doing your books wrong... It's just that profit and cash in the bank are two different things, and nobody really explains that until it bites.

Most of the time these two roughly line up. But sometimes they don't, and that gap is where many business owners get caught out. You can have a great month on paper and still feel like you're scraping to cover wages. It's not because something's wrong; it's that some of the biggest payments only show up on your P&L gradually, and others don't show up at all.

When you make a loan repayment, only the interest counts as an expense on your P&L. The rest (the principal) is money leaving your account to pay down a debt. So, your P&L might show only a small interest cost, while your bank account is missing a much larger amount.

This is all about timing.

PAYGW withheld from your team's pay is already part of your wages expense, so it hits the P&L when you run payroll; but you don't hand it to the ATO until your IAS or BAS is due, often weeks or months later. That payment simply clears a debt you've already recorded.

You won't find GST on your P&L. You collect it on sales and pay it on purchases, but it belongs to the ATO, so you're just holding it for the ATO until you pay your BAS.

Say you spend $30,000 on a new piece of equipment. Your P&L doesn't take a $30,000 hit that month; instead, it spreads the cost over several years as depreciation, a few thousand dollars at a time. Meanwhile, your bank account has already paid the full $30,000.

A few other things work the same way: GST you're holding for the ATO, stock on the shelf that hasn't sold, cash that hasn't made it to the bank yet, and money you've taken out for yourself. They all affect your cash, but none of them shows up on your P&L at the time, and some never will.

You can be profitable, flat out and on top of everything, and still find the bank account empty when a big bill lands. That's especially likely if your trade is seasonal, you're repaying a loan or you're clearing a tax debt. The P&L won't see it coming, because it only tells you what's already happened.

A P&L tells you whether you made money, but it doesn't fully tell you where the money went. To see that, you need to follow the cash.

It's a simple exercise. Start with what was in the bank at the beginning of the month, then work through everything that came in and everything that went out, until you reach what's in the bank now. Then compare that with your P&L, and the gap between them stops being a mystery.

This is where what your P&L leaves out comes into view. The BAS payment that cleared a quarter's worth of GST in one go. The full loan repayment, not just the interest. The ATO payment plan instalment, the stock sitting in the cool room that you've paid for but not sold, and the money you've drawn out for yourself. Each of these is small enough to overlook on its own, but together they explain why a profitable month can leave the account lighter than it should be.

Do this over a few months, especially through a quiet patch, and a pattern emerges. You'll see which months the big payments land, how much the slow season really costs you and how much of your profit is already committed before it reaches the bank. That picture doesn't predict the future, but it means the next lean month or big bill won't take you by surprise.

It's easy to forget, but a profitable business can still run out of money. Profit tells you you're doing well, whereas cash flow tells you whether you'll make it through the week when that big bill comes knocking.

Once you can see where the money has been going, use that to look ahead. A simple tally of what's coming in and what's going out over the next month or two tells you something your P&L never will.

In a nutshell: watch both, and you won't be caught short.
