How Changes in Working Capital Can Affect the Interpretation of Company Accounts

Working capital is an important part of understanding a company's financial position. Changes in receivables, inventory, payables and other short-term balances can affect how a business funds its day-to-day operations and meets its financial obligations.

A company may report revenue growth while the amount of cash tied up in its operations also increases. In other circumstances, a reduction in working capital may reflect improved collection of customer payments, lower inventory requirements or changes in supplier payment arrangements. The significance of a change depends on the circumstances and the underlying financial evidence.

When company accounts are examined as part of a financial dispute or investigation, working capital analysis may help explain changes in liquidity, identify inconsistencies between financial records and highlight questions that require further examination.

This article explains how changes in working capital can affect the interpretation of company accounts and how a forensic accounting review may approach these movements.

What Is Working Capital?

Working capital generally refers to the difference between a company's current assets and current liabilities.

Current assets commonly include cash, trade receivables, inventory and other assets expected to be realised or used within the relevant operating cycle or reporting period, depending on the applicable accounting framework.

Current liabilities may include trade payables, short-term borrowings, accrued expenses and other obligations due within the relevant period.

The basic calculation is:

Working Capital = Current Assets − Current Liabilities

For example, if a company has current assets of £800,000 and current liabilities of £600,000, its working capital is £200,000.

This figure provides a snapshot of the relationship between current assets and current liabilities at a particular date. It does not, by itself, establish whether the company has sufficient cash to meet every payment when due.

The composition of working capital is also important. A company with substantial receivables or inventory may have positive working capital but still experience cash pressure if customers pay slowly or stock cannot be sold as expected.

Why Changes in Working Capital Matter

Working capital changes as a business sells goods, provides services, collects customer payments, purchases inventory and settles supplier invoices.

These movements can affect the relationship between reported performance and the company's available financial resources.

For example, a business may record an increase in sales but allow customers longer to pay. Revenue may therefore rise while more money remains tied up in outstanding receivables.

Similarly, a business may purchase additional inventory in anticipation of future demand. This may increase current assets while reducing the cash immediately available for other purposes.

A forensic accounting review may consider such changes when examining:

• The movement in a company's financial position over time
• Differences between reported performance and cash movements
• Changes in the timing of customer receipts and supplier payments
• The composition and recoverability of current assets
• The completeness of recorded liabilities
• The consistency of management explanations with the available records

These matters do not necessarily indicate financial misconduct. The purpose of the analysis is to understand the movements and assess whether the available evidence supports the explanations provided.

Key Working Capital Components to Examine

Trade Receivables

Trade receivables represent amounts owed to a business by its customers for goods supplied or services provided on credit.

An increase in receivables may reflect higher sales, changes in customer payment terms, seasonal trading patterns or delays in collecting outstanding balances.

In some circumstances, the increase may warrant closer examination, particularly where receivables grow substantially faster than sales or remain outstanding for longer than expected.

A financial review may consider:

• The age of outstanding balances
• Payment dates and subsequent receipts
• Disputed customer invoices
• Credit notes and adjustments
• Changes in customer payment terms
• Balances outstanding at the reporting date
• Differences between sales records and customer account balances

The purpose is to assess the nature and recoverability of receivables, rather than assume that an increase indicates a problem.

Inventory

Inventory may include raw materials, work in progress and finished goods, depending on the nature of the business.

An increase in inventory can reflect planned expansion, seasonal preparation, longer production cycles or changes in demand. It may also require further analysis where stock levels appear inconsistent with sales activity or operational requirements.

Relevant questions may include whether inventory records agree with available stock records, whether valuation methods have been applied consistently, and whether slow-moving or obsolete items have been appropriately considered.

Where inventory values form a material part of current assets, changes in the recorded balance may affect the interpretation of the company's working capital position.

Trade Payables

Trade payables represent amounts owed to suppliers for goods and services received.

An increase in payables may arise from higher purchasing activity, negotiated payment terms or the timing of invoices around the reporting date.

However, a company may also experience pressure on its cash position if it increasingly relies on delaying supplier payments.

A review may examine supplier statements, invoice dates, payment histories, outstanding balances and any disputes concerning amounts owed.

It may also be necessary to consider whether liabilities incurred before the reporting date have been recorded in the appropriate period.

Cash and Short-Term Borrowings

Cash balances and short-term borrowing arrangements can provide additional context for working capital movements.

A reduction in cash may coincide with increased inventory purchases, slower customer collections, repayment of borrowings or other expenditure.

Similarly, an increase in short-term borrowing may indicate that the company is funding a larger operating cycle, although the reason cannot be established from the borrowing balance alone.

Comparing cash balances, bank statements, borrowing records and working capital movements can help explain how the company's short-term funding position has changed.

How Working Capital Changes Affect the Interpretation of Company Accounts

Revenue Growth Does Not Necessarily Mean Improved Liquidity

A company may report higher revenue while experiencing greater pressure on its cash resources.

For example, sales may increase because customers are purchasing more on credit. If customer receipts do not increase at a similar pace, the business may need additional funding to support its operations.

A review may compare revenue trends with receivables, cash receipts and relevant customer payment information.

This comparison can help explain whether changes in sales are accompanied by changes in the timing of cash collection. It does not, by itself, establish whether revenue has been recorded incorrectly.

A Reduction in Working Capital May Have Different Explanations

A fall in working capital may reflect improved collections, lower inventory requirements or the settlement of outstanding liabilities.

It may also arise because cash has declined, inventory has been reduced, or current liabilities have increased.

These circumstances have different implications for the company's financial position. The overall movement therefore needs to be considered alongside its individual components and the wider financial records.

Reporting-Date Balances May Not Show the Full Picture

Working capital figures are commonly reported at a particular date. They may not fully reflect fluctuations that occur during the reporting period.

For example, a company may experience significant seasonal changes in inventory and receivables. A year-end balance may therefore differ considerably from the position maintained during the rest of the year.

Where the distinction matters, a review may compare monthly management accounts, bank statements and other available records rather than relying solely on year-end figures.

Changes in Supplier Payment Timing May Affect Comparisons

A company may report higher working capital because it has negotiated longer supplier payment terms. Alternatively, it may have increased outstanding payables because payments were delayed.

The balance sheet alone may not distinguish between these explanations.

Reviewing supplier agreements, invoice due dates, payment records and correspondence may help clarify the circumstances.

How a Forensic Accountant May Examine Working Capital Movements

Where working capital forms part of a financial dispute or investigation, the analysis may involve several stages.

1. Establishing a Consistent Comparison Period

The starting point may be to compare working capital balances across relevant reporting periods.

The periods selected should be appropriate to the business and the questions being examined. Seasonal trading patterns, acquisitions, disposals and changes in accounting policies may affect the comparability of the figures.

2. Reconciling Balances With Supporting Records

Reported balances may be compared with the underlying accounting records and supporting documentation.

For example, trade receivables may be checked against customer ledgers, invoices and subsequent receipts. Trade payables may be compared with supplier statements, invoices and payment records.

The extent of the reconciliation will depend on the records available and the scope of the review.

3. Examining the Reasons for Material Changes

Where a balance changes significantly, the analysis may consider the transactions contributing to that movement.

A rise in receivables, for example, may need to be separated into additional credit sales, delayed collections, disputed invoices, credit notes and other relevant adjustments.

This helps distinguish the numerical change from the underlying events that may have caused it.

4. Comparing Financial Records With Explanations

Management explanations may provide relevant context, but they can also be tested against available financial and documentary evidence.

If a change is attributed to seasonal trading, the review may consider prior-period figures and available sales records. If it is attributed to extended customer payment terms, the review may examine relevant agreements and collection histories.

The objective is to assess whether the explanation is consistent with the evidence, while recognising any remaining uncertainty.

5. Identifying Limitations

A working capital analysis may be constrained by missing records, incomplete reconciliations, inconsistent reporting periods or uncertainty about the recoverability of certain assets.

These limitations should be identified clearly. Where the evidence does not support a firm conclusion, the analysis should explain what can be established and what remains uncertain.

Working Capital Ratios and Supporting Analysis

Working capital can also be considered through financial ratios and operational measures.

The current ratio compares current assets with current liabilities. The quick ratio considers a narrower group of current assets, generally excluding inventory and other less readily available items, subject to the calculation used.

Other useful measures may include receivable days, inventory days and payable days.

These measures can help show how the timing of customer collections, inventory holding and supplier payments has changed. However, calculations can vary according to the data and methodology used.

Ratios should not be interpreted in isolation. A change may reflect growth, seasonality, a different product mix, altered commercial terms or other business circumstances. Comparisons are most informative when the periods, definitions and underlying data are sufficiently consistent.

Distinguishing Working Capital Pressure From Evidence of Misconduct

A deterioration in working capital does not, by itself, establish fraud, mismanagement or an accounting irregularity.

Changes may arise from legitimate commercial decisions, difficult trading conditions, supply-chain disruption, customer payment delays or planned business expansion.

Equally, where the figures are inconsistent with supporting records or the explanations provided, further investigation may be appropriate.

A careful financial review should distinguish between:

• Changes established by the accounting records
• Explanations supported by documentary evidence
• Assumptions used in the analysis
• Alternative explanations that remain plausible
• Matters that cannot be established from the available information

This distinction is important when financial analysis is being used in a commercial dispute, an investigation or legal proceedings. The firm's areas of expertise provide further context about the financial issues addressed by the practice.

Conclusion

Changes in working capital can materially affect how company accounts are interpreted. Movements in receivables, inventory, payables, cash and short-term borrowings may help explain changes in liquidity and the funding required to support business operations.

A forensic accounting review may compare balances across reporting periods, reconcile figures with supporting records and examine the transactions contributing to significant movements. The findings depend on the quality and completeness of the evidence, as well as the circumstances of the business.

Working capital figures should not be treated as conclusive evidence of financial misconduct. Their significance depends on the composition of the balances, the timing of transactions, the underlying commercial context and the explanations supported by the available records.
