Cash

Profit is not cash: why profitable businesses run short of money, and how to see it coming

---

Profit is a record of the past, the bank balance is a photograph of one morning, and neither answers what you can afford. Where the money sits, why good months bite, and the one page that shows it coming.

An owner showed me a profit figure of £214,000 for the year to date and asked a reasonable question. Could he take a second dividend?

There was £31,000 in the bank.

Both numbers were right. The accounts were not wrong, the bookkeeping was not behind, and nothing had gone missing. The £183,000 between them was exactly where it should have been, which is the part most owners are never shown.

This is the most common conversation we have with owners of established UK businesses, and it is almost never a sign that the business is failing. It is a sign that profit and cash answer two different questions, and that most businesses only track the first one. This piece sets out the whole of it in one place: the three numbers that sound like the same thing, where the money actually sits, the decisions that go wrong, the shape it takes in different sectors, and the one page that fixes it.

Three numbers that sound like the same thing

Profit is what your management accounts report. Revenue is recognised when you invoice, costs are matched to the period they belong to, and the result is a fair picture of whether the business model works. It is a useful number. It just says nothing about whether the money has arrived, and a profitable quarter can sit entirely in unpaid invoices.

The bank balance is real money, which is why owners trust it. Its weakness is timing. It shows today, and today is rarely representative. It does not show the VAT quarter due in three weeks, the payroll run after that, or the corporation tax bill that has been quietly accruing since April.

Spendable cash is the number you are actually reaching for when you ask what you can afford. Take the balance, subtract everything committed to go out over the coming weeks, add what is genuinely due in and when it will really land, and look at the result week by week. That number never appears in your accounts or your banking app. It has to be built, which is why most owner-managed businesses have never seen it.

So a business can be profitable, solvent, well run and entirely unable to fund the decision in front of it. That is not a warning sign. It is the normal condition of a growing owner-managed business, and it is only dangerous when nobody has written it down.

Where the £183,000 was

On his numbers the gap broke down into three parts, and it is nearly always these three.

Money your customers have not paid you yet: £102,000. Work delivered, invoiced, counted as profit, sitting in somebody else’s accounts payable queue. His written terms were 30 days. His actual average was 48. That difference of eighteen days on a business his size was most of the gap on its own.

Tax collected and tax accrued: £46,000. VAT charged to customers and held in his bank account until the quarter is due. PAYE and National Insurance deducted from staff and held until the 22nd. None of it was ever his money. All of it was in his bank balance, which is why it felt like it was.

Costs committed but not yet paid: £35,000. Supplier invoices approved and sitting in the payment run. A quarter’s rent. The corporation tax accruing quietly on the profit he was looking at.

Add those three and the £214,000 of profit turns into the £31,000 that was genuinely available. Nothing was hidden. It was simply never assembled into one view.

The four places cash hides in a profitable business

Widen the lens from one business to the pattern and the hiding places are consistent.

Where it hides	What it looks like	What to do
Debtors	Sales are booked as income but customers pay 30, 45 or 60 days later, and some later still.	Track debtor days monthly, by customer. Chase on a fixed rhythm, not when things feel tight.
Tax building up	VAT collected sits in the account looking like your money. Corporation tax accrues silently all year.	Set aside VAT and corporation tax as you go, ideally in a separate account.
Stock and work in progress	Cash converted into things you cannot spend: stock on shelves, projects not yet billable.	Know your conversion cycle. Bill in stages where the work allows it.
The cost of growth	New hires, kit and bigger premises are paid for months before the revenue they support arrives.	Model the cash impact of growth decisions before committing, not after.

Notice that all four are signs of activity, not failure. That is exactly why profitable businesses get caught: everything looks like progress until the timing bites.

The month it usually bites

There is a familiar shape to it. A strong quarter means a bigger VAT bill. The good months justified a new hire, so payroll is higher. Two large customers slip their payment terms in the same month. None of these alone is a crisis. Landing together, they turn the best trading period of the year into the tightest cash position.

The balance is at its most flattering at exactly the moment you are most tempted to commit. Money in tends to arrive in lumps, money out tends to leave on schedule, so the snapshot peaks between the two and reads as permission.

The painful part is that every one of those items was knowable weeks earlier. The VAT bill was predictable from the day the invoices went out. The payroll increase was a signed contract. The slow payers had form. What was missing was not information. It was a place where all of it came together in one forward view.

A healthy balance and a nearly bad decision

The owner of a professional services business turning over around £3 million looked at the bank in August and saw the best balance of the year, a little over £160,000. Two large invoices had just been paid and the quarter’s bigger bills had not yet gone out. On the strength of it, the plan was two senior hires starting in September and a dividend before the year end.

The 13-week view told a different story. A £48,000 VAT bill sat three weeks out. Payroll ran every month regardless. A corporation tax instalment landed in the middle of the quarter, and the biggest customer had drifted from 30 days to nearer 50 without anyone chasing. On the existing commitments alone, the low point came in week nine, at around £11,000. Add two salaries and a dividend and week nine went below zero.

The answer was not “don’t hire”. It was to move the start dates to November, stage the dividend, and put the chasing of that customer on someone’s desk. Same decisions, different timing, and no awkward conversation with the bank. That is what the forward view buys you: not caution, timing.

The dividend question

The dividend question matters more than it sounds, because it is where profitable businesses most often get into difficulty.

A dividend has to be paid out of distributable profits, which is a test about reserves rather than about the bank balance. A company can pass that test comfortably and still not have the cash, and paying anyway means funding the dividend out of money that belongs to HMRC or to suppliers. The tax does not go away. It arrives on a fixed date, usually when the next quarter’s VAT is due as well.

That is how profitable businesses get into difficulty: not through losses, which are obvious and get acted on, but through a sequence of reasonable decisions made against the wrong number.

We are not giving you advice on your own dividend here, and the position depends on your reserves, your year end and your own circumstances. The point is narrower: the bank balance is not the test, and neither is the profit figure on its own.

The same problem in three sectors

Sector changes the shape of it, not the cause.

Professional services and agencies. The gap is almost entirely debtor days. Work is delivered and invoiced monthly, clients pay on 30, 45 or 60 days, and the difference between the terms on the invoice and the date the money lands is the whole story. A client sliding from 30 days to 55 changes your profit by nothing at all and moves your cash by weeks.

Recruitment, and any business that pays people weekly. On a contract desk the agency pays contractors within a week and invoices the client at month end, and the client pays six or seven weeks after that. The distance between paying for a week of work and being paid for it is often nine weeks. Multiply the weekly contractor pay run by that gap and you have the amount of your own money permanently inside the book. Every new placement is an investment before it is income, which is why a record billing month is so often the tightest month in the bank.

Software and subscription businesses. Revenue and cash move on completely different clocks. An annual contract is booked as revenue and paid in twelve monthly instalments while the cost of serving it starts on day one. Hiring runs ahead of revenue because the backlog says it should. Churn hides inside a recurring revenue chart that new sign-ups keep flat. Bookings up, monthly recurring revenue up, bank balance down, all at the same time.

The trading is fine in all three. The timing is what bites.

What to measure instead

Three things, and none of them needs a new system.

Your real days to pay, by customer. Not your terms, which are what was agreed, but what actually happens. Pull it by customer rather than as an average, because averages hide the two or three accounts doing the damage. Then put last year’s figure next to this year’s. If it has grown, that is not drift, that is a decision being made for you.

Your tax set-aside. The share of the bank balance that is already owed. The owners who never get caught move VAT into a separate account the day the money lands, so there is no month where leaving it feels affordable. Corporation tax works the same way. There is no single safe percentage, because it depends on your margins, your VAT position and how you pay yourself; calculate it from your own numbers monthly and move it out of the working account.

Your available cash, as a number. Bank balance, less tax held, less committed costs. That is the figure that answers the question the owner was really asking. Most owners have never calculated it, and almost all of them are surprised by it the first time.

The dates that are already fixed

For a company with a 31 March year end, the next few months are more or less written.

VAT for the quarter to 30 September is due on 7 November. Corporation tax on the year just ended is due on 1 January. Personal tax on dividends already taken is due on 31 January. PAYE leaves on the 22nd of every month whatever else is happening.

None of that is a surprise. All of it is knowable today. What catches owners out is not the existence of the bills, it is that nobody put them on the same page as the cash coming in. Tax stops arriving like weather the moment it sits in the same view as the money due in.

What a 13-week cash view actually is

It is one page. Thirteen columns across the top, one per week, starting with the week you are in. Down the side, three groups of lines.

What is coming in. Customer receipts, dated by when each customer actually pays, not by the terms printed on the invoice. If they average 47 days, the forecast says 47 days.

What is going out. Suppliers, subcontractors, software, marketing, the costs you have some say over week to week.

What is committed and cannot move. Payroll, PAYE, pension, VAT, corporation tax instalments, loan and finance payments, rent, the owner’s own drawings.

The third group is the one that does the damage when it is missing. Committed costs leave on schedule whatever else is happening that week, and they are the reason a good month can still contain a bad Friday.

Across the bottom, three lines. Best case assumes the good outcomes land: the late payer pays, the new contract starts on time. Expected is what you would put money on. Downside assumes the two or three things most likely to slip do slip. The gap between those lines is your margin for error, and seeing it as numbers beats carrying it around as a feeling.

Why thirteen weeks? It is a quarter. Far enough out to catch a full VAT cycle and every payroll run, near enough that most of what you are looking at is already committed rather than forecast. Beyond that you are guessing. Inside it, you are mostly reading what is already decided.

The number to look at is the low point

The number owners look at first is never the total. It is the low point: the week where the balance dips furthest. That week decides whether the decision in front of you is affordable, because a plan that works in weeks one to eight and fails in week nine has failed.

Most businesses find the low point is not where they assumed. It is rarely the quiet trading month. It is usually the week a VAT quarter, a payroll run and one slow invoice happen to line up, which is a timing accident rather than a trading problem.

Once you can see it, you have options that were invisible before. Move a start date by six weeks. Stage a dividend across two quarters. Put the chasing of one customer on somebody’s desk with a date against it. Ask one supplier for 45 days. None of those is dramatic, and any one of them can move the low point far enough for the answer to become yes.

How often to rebuild it, and whose job it is

1. Rebuild it every week. Same day each week, same half hour: roll the window forward, put in what actually happened, and correct the dates that moved. The discipline matters more than the spreadsheet.
2. Give it an owner who is not the business owner. It needs someone with the bank, the sales ledger and the purchase ledger in front of them every week. A bookkeeper who has been shown what to do, a finance manager, or an outsourced finance function. The arrangement that reliably fails is the MD doing it on a Sunday night.
3. Check the assumptions against what happened. Record when each customer really paid against what the forecast said. After a month or two the dates stop being guesses and start being evidence, and the forecast gets noticeably harder to argue with.
4. Set trigger points. Decide in advance what happens if the projected low point drops below a set floor: which spend pauses, which chase calls happen, what gets rescheduled. Triggers beat panic.

It takes an afternoon to build the first time and about twenty minutes a week after that. A forecast built once and left alone is out of date within a fortnight. Kept live, it quietly becomes the one page every decision gets tested against.

How to tell whether this is you

Three questions settle it quickly.

Can you say what the bank balance will be in week nine, and what it would be if your largest customer paid a month late? Which single week between now and the year end is the tightest, and how tight does it get? If a good hire became available on Monday at £55,000, could you answer yes or no without opening the banking app first?

If those take more than a day to answer, the gap is visibility rather than profitability. Most owner-managed businesses we meet are profitable. What they are missing is a forward view, and a surprise VAT bill, a quietly slipping customer, a tight payroll week and decisions made off the morning balance are what its absence looks like from the inside.

The practical point

Work out one number this week.

Take your bank balance. Subtract the VAT and PAYE you are holding. Subtract the supplier payments already approved. Subtract the corporation tax that has accrued on the profit so far.

What is left is what you can actually spend.

Most owners find it is a good deal less than they thought, and almost all of them would rather know in September than in January. If two of you run the business, work it out separately before you compare. The gap between your two answers is usually the conversation worth having.

Then ask the second question: what does the week-by-week cash position look like for the next thirteen weeks, and where is the low point? If nobody in your business can show you within a day, that is the gap to close first, before the next commitment rather than after it. That upkeep is finance operations work, the layer that sits between bookkeeping and the big strategic calls, and it is the layer most owner-managed businesses are missing.
