Reading cash flow statements with a sceptical eye

The books say you made 8,000. The bank is 15,000 lower than it was in January. Both are correct, and the 23,000 between them is a list of specific events, each one identifiable.

A cash flow statement is that list, and reading it well means reading the bridge rather than the bottom line.

What to take away

Where the two numbers separate

Profit measures earning. Cash measures the bank. Five ordinary events pull them apart.

You earned it and have not been paid. The sale sits in profit; the money sits in someone else's account.

You paid before you consumed. Stock on a shelf and a year of insurance paid up front are cash gone and cost not yet charged.

Someone else is waiting on you. An unpaid supplier invoice is a cost recorded while the cash is still yours.

You bought something that lasts. The full price left the bank; only this year's slice reaches profit.

Money moved for reasons that are not trading. A loan received, a loan repaid, money the owner took out.

None of these is an error. Together they let profit and cash point in opposite directions for years.

The three sections, and what each one proves

Operating is cash from running the business: customers paying, suppliers being paid, wages, rent, insurance. It is the only section that can continue indefinitely, which is why lenders read it first.

Investing is cash spent on or received from long-lived things: equipment, vehicles, leasehold improvements. A negative investing figure is not automatically bad news.

Financing is cash to and from the people funding the business: loans drawn and repaid, capital introduced, dividends and drawings taken. Positive financing cash means the business needed outside money this period.

A business with negative operating cash propped up by financing is running on borrowed time in the literal sense. A business with strong operating cash and heavy investing is probably growing. The bottom line can be identical in both cases, which is exactly why the split exists.

The indirect bridge, worked through

The indirect method starts at profit and removes everything that was not cash. Every figure below is invented to expose the mechanism.

Read the middle block again. Trading generated 18,000 before working capital and 1,000 after it. Growth in receivables and inventory consumed almost everything the business earned in the period.

That is the mechanism by which a profitable, growing business runs out of money, and it is invisible on the profit and loss statement alone.

The sign rule, and why it is not arbitrary

An asset going up uses cash. More owed by customers, more stock, more prepaid cover: all of it is cash you have parted with or not yet received. Subtract it.

A liability going up provides cash. More owed to suppliers, more tax not yet paid, more deposits held from customers: all of it is money sitting in your bank that belongs elsewhere. Add it.

The reverse holds in both directions. This is not a convention to memorize; it follows from what the words mean, which is why it survives every reclassification an accountant makes.

Direct and indirect presentation

The statement above is indirect: it starts at profit and reconciles to cash. It is the more common presentation because it is built from figures already in the ledger, and because the reconciliation itself tells you where the money went.

The direct method lists actual cash movements instead: cash received from customers, cash paid to suppliers, cash paid to employees. It reads more easily for a non-accountant and costs more to produce, because it needs the cash movements analyzed rather than the profit adjusted. Both arrive at the same total.

For internal use the indirect version usually answers the urgent question, which is rarely "how much came in" and almost always "why is it not here".

The working capital cycle underneath it

Working capital movements are not random. They are the visible result of a cycle with a measurable length.

You order and pay a supplier. Some days later you sell. Some days after that you are paid. The gap between money leaving and money returning has to be funded by someone: you, a lender, or your suppliers.

Its size shows up as working capital on the balance sheet, so the two documents are read together.

Lengthen the gap and every extra sale makes the funding problem larger. That is why growth so often arrives with a cash crisis: more sales on the same terms tie up more of your money at any moment.

Three levers shorten the gap without a bank. Invoice sooner, collect sooner using the escalation in the accounts receivable guide, and hold less stock.

A fourth is negotiating longer supplier terms, covered from the other side in the accounts payable overview. The caveat: it moves the burden onto a supplier whose goodwill you may need later.

Where a forecast differs from a statement

A cash flow statement explains a period that is over. It cannot tell you whether you can meet payroll in six weeks.

That is a forecast, a different document: opening bank balance, expected receipts by date, committed payments by date, week by week.

Two rules make it useful. Build it from your actual receivables and payables ledgers, not from your profit plan. Record your assumptions in writing, so when the forecast is wrong you learn which assumption failed instead of losing faith in forecasting.

A statement is auditable history. A forecast is a set of dated guesses you can check against what actually happened, and the checking is the part most businesses skip.

What to watch as it moves

Trends in your own figures beat any published benchmark, which cannot know your terms, your industry or your seasonality. Track these over at least two years:

Reconciliation is what makes any of it true

Every figure above depends on the bank record being complete, and that is a bookkeeping discipline rather than a reporting one.

Reconcile the bank to the statement monthly, and reconcile to items rather than to the closing figure. A balance can agree while two errors cancel out. The bookkeeping foundations guide makes that point about proof.

Investigate every unexplained deposit before coding it as income. It is at least as likely to be a transfer, a refund or a loan.

Keep transfers between your own accounts out of income and expenses. A business that counts its own transfers invents revenue and costs at the same time.

Keeping business money in accounts of its own, as the public guidance on opening a business bank account describes, makes that separation possible.

Producing the numbers, and acting on them

Classifying movements into the three sections, reconciling the bank and keeping the working capital ledgers clean are bookkeeping tasks, and they are what make the numbers real.

Deciding how to close a funding gap starts with knowing the ordinary routes to business funding. Whether to raise finance, and in what form, comes next.

Whether an arrangement is a loan or something else, and how to present cash flows to a lender, are questions for an accountant. So is what to do when a forecast shows you cannot meet an obligation, which may need an insolvency specialist.

Trading while unable to pay debts carries duties that vary by jurisdiction, and they are not something to work out from a spreadsheet. Take the forecast and the reconciliations to that conversation early, while options remain.

Common questions

Do we need this if we watch the bank balance daily?

The balance tells you where you are. The statement tells you how you got there, and only the second one helps you predict the next period. Watching the balance alone is how a business discovers a shortfall on the day it arrives.

Which section do customer deposits belong in?

Operating, as a movement in a liability. Money received before the work is done is cash in with no revenue attached, so it appears as a working capital movement rather than as a sale. When the work is delivered, the liability unwinds and revenue appears without new cash.

Is it worth building one by hand once?

Yes, for a period you already understand well. Almost every later question about whether the software's version is right becomes answerable, and the exercise takes an afternoon. Do it in a month with no unusual transactions if you can.

What is the most common classification error?

A loan receipt recorded as income, and a repayment recorded entirely as a cost. Both arrive as ordinary bank deposits and withdrawals, and neither is trading. The interest portion is the only part of a repayment that belongs in profit.
