Profit Is Not Cash: Why Profitable Businesses Still Run Out of Money
A business can report a healthy profit and still struggle to pay wages, suppliers or tax.
There is no contradiction.
Profit and cash measure different things.
Profit tells you whether the business created economic value over a period. Cash flow tells you when money actually entered and left the bank.
The two eventually connect, but rarely at the same time.
Customers pay after sales are recorded. Stock is bought before it is sold. Equipment can be paid for years before its accounting cost is fully recognised. VAT and tax fall due on their own timetable.
And when a business grows, those timing gaps often get larger rather than smaller.
Understanding that gap is one of the most useful things a business owner can do.
The difference, in one example
A business invoices £50,000 in March. Its costs for that month are £35,000, all paid when incurred.
Under accruals accounting, the revenue is recognised when it is earned, so profit for March is £15,000. The accounts are correct, the business is profitable, and everything looks healthy.
But the customer pays in June.
So in March, April and May, the business has paid out £35,000 and received nothing. It has to fund three months of costs from somewhere before the £15,000 profit turns into money it can actually use.
Nothing has gone wrong. The business is profitable and the customer is good for the money. But for three months it needs cash that the profit figure does not tell it about.
Where the gap comes from
Five things move money in and out of a business on a different timetable from the profit calculation.
Customers who pay late
This is the largest one for most businesses.
Under accruals accounting, income is recognised when it is earned rather than when the customer eventually pays. The money arrives when the customer decides to pay. On 30-day terms, paid at 45 days, that is a month and a half between the profit and the cash.
The faster you grow, the worse this gets. More sales means more invoices outstanding at any one time, which means more money tied up. If debtor days remain broadly unchanged, doubling turnover can roughly double the amount tied up in trade debtors.
Stock
Money spent on stock leaves the bank when you pay for it. It only comes back when the stock is sold and the customer pays.
For a retailer or anyone holding inventory, the gap between those two events can be months, and it is money that is entirely invisible in the profit figure.
VAT
VAT is not business income, but it passes through the bank account.
You collect VAT from customers and, after taking account of recoverable input VAT, pay the balance to HMRC. For most businesses filing quarterly VAT returns, the return and payment are due one calendar month and seven days after the end of the VAT period.
A quarter ending 31 March therefore normally creates a payment deadline of 7 May.
Treating VAT collected as ordinary available cash can make the bank balance look healthier than it really is.
Tax payments
Tax liabilities and tax payments do not necessarily arise at the same time as the profits that created them.
For a company with taxable profits of up to £1.5 million, Corporation Tax is normally payable nine months and one day after the end of the accounting period. The tax expense may already be reflected in the accounts, but the cash does not leave the bank until later.
For sole traders, Self Assessment Income Tax is a personal tax liability rather than a business expense. Payments on account normally fall on 31 January and 31 July.
In both cases, a profitable period can therefore create a substantial future cash requirement that is not obvious from today's bank balance.
Equipment and capital purchases
Buy a £12,000 van outright and £12,000 can leave the bank immediately.
Under accruals accounting, however, the van is normally recorded as an asset and its accounting cost is recognised over time through depreciation.
Capital allowances are separate: they affect the tax computation rather than the accounting depreciation charge shown in the profit and loss account.
So the cash account may show a £12,000 outflow today while the profit and loss account reflects the cost differently over time.
Growth is the one that catches people out
This is counterintuitive enough to be worth stating plainly.
A growing business consumes cash. Often more than a stable one.
Consider a business with 30-day payment terms whose monthly sales rise from £20,000 to £40,000 over six months.
Every month it is invoicing more than it did the month before. Every month it is paying for the materials, wages and overheads of that larger volume. And every month, the money for the sales it made is arriving a month or more behind.
The faster the growth, the larger the gap between what has been spent and what has come in. The business is more profitable than it was, and tighter on cash than it was, at the same time.
This is one reason growing businesses can fail despite being profitable: they run out of working capital before the cash generated by that growth arrives.
Growth has to be funded. Either from retained cash, from an overdraft or facility, or by shortening the gap.
The figures that matter
Three numbers tell you most of what you need to know, and none of them appear on a profit and loss account.
Debtor days
How long, on average, customers take to pay.
If your terms are 30 days and your debtor days are 55, you are financing your customers' businesses for nearly four weeks longer than you agreed to.
Watch the direction of travel, not just the number. Debtor days creeping up is an early warning that shows before the bank balance does.
Creditor days
How long you take to pay your suppliers.
This is the other side of the same coin, and it is a lever you can influence. Paying every invoice the day it arrives is generous, but it costs you cash.
Paying to terms — not late, but not early either — is normal commercial practice.
The cash conversion cycle
This measures how long cash is tied up in the operating cycle.
Broadly, it combines the time stock is held and the time customers take to pay, less the time the business has before it must pay its suppliers.
A longer cycle generally means more working capital is needed to support the same level of sales. Shortening the cycle releases cash.
What actually helps
Forecast forward, not backward
Management accounts tell you what happened. A cash flow forecast tells you what is about to happen.
A rolling 13-week cash flow forecast is a widely used short-term management tool. It is particularly useful where cash is tight, the business is growing quickly, customer payment timing is uncertain, or significant payments are approaching.
The objective is not perfect accuracy. It is early visibility.
Seeing a possible shortfall in week nine gives you time to chase debtors, delay discretionary spending, renegotiate payment terms or arrange funding before the problem reaches the bank account.
Invoice sooner
The single fastest improvement available to most businesses.
Invoicing at the end of the month instead of on completion adds up to thirty days to every payment cycle, for no reason other than habit.
Same for the terms themselves. Thirty days is a convention, not a law. Fourteen is perfectly normal in many sectors, and asking is free.
Chase properly
Most late payments are not disputes. They are invoices sitting in somebody's approval queue.
A polite reminder a few days before the due date, and another on the day it falls due, collects a surprising amount of money that would otherwise sit there for weeks.
Set aside the money that is not yours
VAT collected and PAYE deducted are not business income. They are amounts that will have to be paid over.
Some businesses find it useful to move an estimated VAT and PAYE reserve into a separate savings or tax account as the liability builds up. This is a cash-management discipline rather than a legal requirement, but it prevents tax money from being mistaken for operating headroom.
Know your tax dates before they arrive
Corporation Tax is normally payable nine months and one day after the year end. If your year end is 31 March, the money is due by 1 January — and the return that calculates it is not due for another three months.
That means you need a reasonable estimate of the liability well before the return is prepared. Working backwards from the payment date rather than the filing date is the difference between a planned payment and a scramble.
Look at the trend, not the balance
A healthy bank balance today tells you very little. What matters is the direction: is the balance higher or lower than it was three months ago, at the same point in the cycle?
Seasonal businesses in particular need to compare like with like. August against August, not August against July.
The questions worth asking yourself
- If your largest customer paid sixty days late, could the business absorb it?
- Do you know, without looking it up, what your average debtor days are?
- Is the money you have set aside for VAT and PAYE actually set aside, or is it just in the current account?
- Do you know what your bank balance is likely to be at the end of next month?
- If you won a contract that doubled your turnover, do you know whether you could fund it?
A "no" to the last one is worth taking seriously. Winning a contract you cannot fund is a worse outcome than not winning it.
Profitable but tight?
If the accounts look fine but the bank balance never seems to reflect it, the gap is usually explainable — and once it is explained, it is usually manageable.
