A mismatch is not yet a contradiction
Imagine a company reporting a profitable quarter while cash has barely moved and trade receivables have risen. It is tempting to ask which statement is telling the truth.
That is usually the wrong first question.
The company may have delivered the promised product or service, recognised revenue and booked a receivable, while its customer is still due to pay. The three statements are not necessarily disagreeing. They may simply be recording the same event at different moments.
This matters because financial statements are often read as three separate stories: one about performance, one about what the company owns and owes, and one about cash. A more useful mental model is three views of the same economic system. One view records recognised performance over a period. One shows what remains at the reporting date. One records when cash actually moves.
So this is not a glossary of account names. We will follow a transaction through recognition, the reporting-date balance and cash settlement. Only after that route is clear is it sensible to ask whether a difference reflects business economics, timing, classification or an accounting judgement.
One event, three questions
The balance sheet is primarily a point-in-time view: what resources and claims exist at the reporting date? The income statement and cash-flow statement are primarily period views: what changed during the period? The IFRS Conceptual Framework provides the underlying distinction between resources, claims and changes in them.
That is more than a tidy definition. A quarter-end receivables balance and a quarter of revenue are not automatically comparable just because both appear in a report. Before drawing a conclusion, the period length, reporting entity, currency, scale and measurement basis need to line up.
There are also two clocks at work:
- Recognition: when revenue or expense is recorded because an economic event has occurred.
- Settlement: when money is received or paid.
The balance sheet preserves what has not settled at the reporting date: receivables, payables, inventory, prepayments, borrowings and so on. Cash flow records actual cash movement and its activity category. Revenue, profit and cash can move together, but they are not interchangeable measures.
Trace 1: a sale before the customer pays
Use a deliberately simple example. A company completes a service in December under a contract that allows the customer to pay the following month. Ignore tax, discounts, foreign exchange, leases, acquisitions and every other complication for the moment.

| Point in the transaction | Income statement | Balance sheet | Cash-flow view |
|---|---|---|---|
| Service is completed | Revenue and profit may be recognised when the relevant conditions are met | A receivable may arise | No cash from that customer has arrived yet |
| Reporting date | The period’s performance includes the recognised sale | The receivable remains outstanding | Under the indirect method, profit is reconciled for non-cash, accrual and deferral effects |
| Customer pays later | The same sale does not become new revenue again | Receivable falls; cash rises | The operating settlement becomes visible in cash movement |
This is an illustration, not a universal journal-entry template. The important point is that collection is not itself the sole trigger for revenue recognition. IFRS 15 connects revenue to the transfer of promised goods or services under the contract. IFRS 15
The cash-flow statement is not a second income statement. IAS 7 separates operating, investing and financing cash flows. When the indirect method is used, it starts from profit and adjusts for non-cash items, accruals and deferrals, and income or expenses associated with investing or financing.
So when profit rises while operating cash does not, begin by asking where the difference is sitting at the reporting date. Is it in receivables, inventory, prepayments, payables, or another non-cash or timing item? “Which statement is wrong?” can wait.
Trace 2: paying cash is not always an expense; receiving cash is not always revenue
The same route works for other transactions.
Suppose the company pays cash for equipment that will be used for years. The cash payment is an investing-cash-flow candidate. The balance sheet gains property, plant and equipment. It does not follow that the whole cash payment is immediately an expense. Depreciation and, where relevant, impairment affect profit and the carrying amount over later periods. IAS 16 sets the relevant recognition, cost and subsequent-measurement principles; the full answer for any transaction still depends on its facts.
Now take a borrowing. Cash rises and a liability rises. That may strengthen short-term liquidity and it belongs to the financing side of the cash-flow picture, but it is not revenue. Treating borrowed cash as proof of operating improvement confuses the source of funding with the output of the business.
These are small distinctions with large consequences:
- A cash outflow need not be a current-period expense.
- A cash inflow need not be current-period revenue.
- A recognised amount need not have settled in cash.
Reading the statements together forces a more useful question: did this cash come from operations, investment or financing, and what asset, liability, equity balance or unsettled working-capital item did it leave behind?
A bridge can close and still tell the wrong story
A reconciliation is necessary. It is not a certificate that the economic explanation is complete.
Some differences are operational. Others result from accounting policy, an estimate, an error correction, classification or the reporting boundary. These categories must not be thrown into one vague bucket called “accounting changes”. IAS 8 distinguishes accounting policies, accounting estimates and prior-period errors because they are different kinds of change with different implications.
When a trend suddenly looks better, pause over four questions:
- Am I comparing the same reporting entity, period length and measurement basis?
- Is the movement driven by volume, price, cost or collection timing — or by a policy, estimate or presentation change?
- Are non-cash items, one-off items or opening-and-closing balance movements making the period look more dramatic than it is?
- Is this a signal to investigate, or a conclusion already proved?
The fourth question protects against a common analytical leap. A strange ratio or journal pattern may justify further testing; it is not, by itself, proof of manipulation or fraud. PCAOB AS 2401 treats fraud-risk considerations as inputs to audit responses, not as automatic accusations.
Turn the reconciliation back into a question
Here is a management workflow, not an IFRS or PCAOB rule. Its purpose is to prevent a closed numerical bridge from being mistaken for a causal explanation.
- Set the boundary. State the metric, period, entity and accounting basis.
- Close the bridge. Walk from opening balance to closing balance, separating operating movement, non-cash effects, classification and one-off effects.
- Locate the concentration. If a material residual remains, split it by the dimensions that fit the business: product, customer cohort, channel, geography or something else defensible.
- Write a falsifiable hypothesis. Replace “this is the root cause” with “if this is the main mechanism, what else should we observe?”
- Seek corroboration and disconfirmation. Check data reliability, timing and alternative explanations. A bridge can allocate a movement; it cannot prove causality on its own. PCAOB AS 2305 is useful here for its emphasis on plausible relationships, reliable data and investigation of significant differences; causal inference also requires care over the assumptions that would rule out competing explanations. NBER Working Paper 29787
- Choose a proportionate action. Assign an owner, a review point and a guardrail that match the confidence of the evidence. Weak evidence should lead to reversible action, not certainty theatre.
This does not turn every operator into an auditor. It turns financial statements from a scoreboard into a map of questions worth answering.
Use this sequence on the next set of accounts
When a number moves, resist the urge to label it good or bad immediately. Ask what transaction produced it. Ask when it was recognised, what was still on the balance sheet at the reporting date, and when cash settled. Then ask whether a policy, estimate, classification or reporting-boundary change has altered the comparison.
If the three statements can be connected into one route, the reader is no longer memorising three documents. They are observing how a business moves through recognition, balances and cash — and identifying the next question the evidence has not yet answered.
