Why profit and cash are not the same.

Where the cash from a profitable month goes, and a 13-week forecast that shows it in advance.

Profit and cash are not the same thing because they measure two different events. Profit is what you earned less what it cost you over a period, counted when the work was done and the invoice was raised — whether or not a penny has moved. Cash is what has arrived in, and left, your bank account. The gap between them is partly timing, and partly a short list of payments that never appear in a profit and loss account at all: money your customers owe you, the capital element of loan repayments, VAT and corporation tax, and the money you take out as drawings or dividends.

So a profitable month can leave less in the bank than you started with. A rolling 13-week cash forecast and three monthly numbers show this in advance, built from a spreadsheet and records you already hold in about two hours.

What is the difference between profit and cash?

Profit answers the question “did the trading work?” It matches income to the cost of earning it, in the period the work happened. Raise a £10,000 invoice in March for work you did in March and March earned £10,000 of revenue, even if the money lands in May.

Cash answers a different and more urgent question: “can I pay everyone on Friday?” It counts only money that has moved. Both are true at the same time. A business can be profitable and unable to make payroll, and it can be loss-making and comfortable for a while — often because it has been paid up front for work it has not yet delivered.

The profit and loss account reports the past, so it cannot tell you what will be in the bank in eight weeks. Forecasting is a management job, and Financial Coaching covers it session by session.

What never shows up in your profit figure?

Four things take cash out without ever appearing as a cost in your profit and loss.

Add stock and work in progress and you have the full picture. Both are cash you have already spent, sitting on the balance sheet as an asset rather than in the profit and loss as a cost.

How can a profitable month cost you £53,000?

This is the arithmetic as your bank statement sees it.

An illustration of the shape — not a client, and not a claimed result. A business posts a good month: £18,000 profit before tax. Then the cash. Debtors rise by £26,000, because two large invoices went out on 45-day terms. Work in progress and stock rise by £4,000. The quarterly VAT bill of £19,000 falls due. Corporation tax on last year’s profit takes £11,000. The loan capital repayment takes £6,000. The owner draws £5,000. Net movement: minus £53,000.

Sort those items into two piles. The VAT, the corporation tax and the loan repayment are fixed and dated, so put them in the diary months ahead. The £26,000 of debtors and the £4,000 of work in progress are the two you can influence. Pulling debtors in by a fortnight in that illustration releases around £13,000 of cash, once.

Why does growth make the cash gap worse?

Growth is funded before it pays. More people, more stock, more capacity and more work in progress all consume cash ahead of the revenue they create. Double the sales and you roughly double the money tied up in unpaid invoices at any one moment — so the better the quarter, the tighter the bank account.

A business can be profitable, expanding and three weeks from a serious problem at the same time. If growth is the current agenda, the cash consequences of the plan belong inside the plan. It is a standing item in Business Coaching, and it is the subject of the Cash Conversion Cycle model: how long you wait between paying for something and being paid for it.

How do you build a 13-week cash forecast?

Use a spreadsheet with a column for each of the next 13 weeks and three blocks of rows.

  1. Money in, by week. Take your unpaid sales invoices and put each one in the week you expect it to be paid, not the week it is due. If a client habitually pays at 60 days when your terms say 30, forecast 60. Then add standing income, deposits, refunds and anything else you expect.
  2. Money out, by week. Payroll, PAYE, rent, suppliers, subscriptions, VAT, corporation tax, loan repayments, drawings. Take the dated items from the diary and the recurring ones from your bank statement rather than from memory, because memory reliably understates them.
  3. Closing balance. Opening balance, plus money in, less money out, carried into the next week. That row is the output.

Look for weeks where the balance dips below zero, or below the level you are comfortable with. Eight weeks out, you can chase a specific invoice, ask a client for a stage payment, move a purchase by a fortnight or arrange a facility calmly. Spend fifteen minutes at the end of each week putting the actuals next to the forecast.

Which three numbers should you check every month?

Common questions

My accountant handles the numbers — why do I need a cash forecast?

Your accountant records what happened and keeps you compliant. A forecast is about what is going to happen, which is a management job. Year-end accounts arrive months after the period they describe. A 13-week forecast tells you about next month while there is still time to act on it. Many accountants will help you build the first version and check the tax dates inside it. The weekly updating has to sit with you, though, because you are the one who knows which invoice is going to be paid late.

How far ahead should I forecast?

Use two horizons. Thirteen weeks, week by week, is the operational forecast: close enough to be accurate, far enough ahead that a problem can still be solved calmly, and short enough that you will keep it updated. Twelve months, month by month, is the planning forecast: it is where tax payments, seasonal dips, loan repayments and any hiring or investment plans get tested before you commit to them. If you only ever build one, build the 13-week version and roll it forward every Friday.

Will an overdraft or invoice finance fix a cash gap?

They buy time at a cost, so arrange them before you need them. What they do not do is fix the cause. If the gap comes from prices that are too low, terms that are too long or collection that is too polite, borrowing funds the same problem for longer and adds interest to it. Use the forecast to work out which one you have: a timing gap that closes on its own, or a structural gap that will keep reopening every quarter. Fund the first. Fix the second, then decide whether you still want the facility.

How much cash should the business hold?

Set the target in weeks of fixed costs rather than as a round number, because a business with £30,000 of monthly fixed costs and one with £8,000 are in very different positions holding the same balance. Six weeks of fixed costs is a sensible floor if your income is steady and contracted. Twelve is closer to right if it is lumpy, seasonal or concentrated in a handful of clients. Write the number down, put it on the forecast as a visible line, and act when the balance drops below it: chase an invoice, delay a purchase or have a conversation.

The money in the bank includes VAT and tax I owe. How do I stop spending it?

Separate it the day it arrives, not the week the bill does. Open a second account and, on the same day you reconcile each week, move across the VAT on everything you have invoiced plus a provision for corporation tax. Since 1 April 2023 corporation tax has been 19% on profits up to £50,000 and 25% on profits over £250,000, with marginal relief tapering between the two, so setting aside a fifth of profit is a safe working provision for most small companies. The main account then shows a number that is yours to spend.
