A Good Year Can Empty Your Bank Account

The businesses that run out of cash are often not the ones losing money. They are the ones growing.

That sounds backwards until you see what profit is. Profit is a calculation about a period of time. It counts a sale when you make it and a cost when you earn the revenue it belongs to. Cash is what is in the account today. Your staff, your landlord and your suppliers only accept the second one.

So a business can report its best year and still be unable to make payroll on Friday. Nothing is wrong with the accounts. The profit is real. It just is not in the bank, because it has gone somewhere else.

The Five Places Your Profit Goes

Most of the gap between profit and cash comes from five places. Four of them never appear on your profit and loss statement at all, which is why they catch owners out.

1. Into your customers' hands

Every invoice not yet paid is profit you have reported and cash you do not have. When sales grow, the amount your customers owe you grows with them. See what to do about customers who pay late.

2. Onto your shelves

Stock is cash in a different shape. You pay for it now and only count the cost when it sells. Buy ahead for a busy season and your profit does not move, but your bank balance does.

3. Into equipment

A $30,000 vehicle costs $30,000 of cash on the day you buy it. On your profit and loss, that cost is spread over years. The business feels fine on paper and short at the bank.

4. Into repayments

Only the cost of funding reaches your profit and loss. The money you repay does not, yet it leaves your account all the same. A business can look profitable while most of that profit goes straight back out.

5. Into your own pocket

What you take out as an owner may not count as a cost at all. It still leaves the account, and it is often the largest line nobody forecasts.

Your cash flow statement shows all five. It is the one report built to answer this question.

A Worked Example

Say a business made $100,000 of profit this year, its best yet. It starts the year with $50,000 in the bank and expects to end it with $150,000. Here is what really happened:

Customers owe $30,000 more than a year ago
Stock is up $25,000
It bought $30,000 of equipment
It repaid $20,000 of funding
The owner took out $15,000

$100,000 − $30,000 − $25,000 − $30,000 − $20,000 − $15,000 = −$20,000.

The business made $100,000 and its cash fell by $20,000, from $50,000 to $30,000. Every decision on that list was reasonable. Added together, they took the balance the wrong way in the best year it ever had.

The Slate View

Treat a good year as the moment to worry about cash, not the moment to stop. Slate looks at a business from the outside, starting with what actually moved through the bank, and from there growth and strain can look identical.

So stop asking "how much did we make?" and ask "where did it go?" Walk your profit down those five lines once a quarter, in dollars. The largest line is your real decision. If it is customers, you have a collections problem wearing a sales win. If it is stock, you are betting on next season. If it is equipment, you have turned a short-term balance into a long-term asset, and you need to know how you will pay next month's bills while it earns its keep.

A healthy margin does not protect you from any of this. As we say in gross margin vs net margin, margin tells you what you earn over time, not what you can pay this week.

Where to Go Next

Work through it in this order:

Measure how long you have. Use the cash runway calculator.
Work out what your cycle ties up. See how much working capital your business needs.
See the tight weeks coming. Build a 13-week cash flow forecast.
Fund the gap only if it is timing. Compare a credit line and a cash advance.
