How to analyze working-capital swings in quarterly results: ΔAR, inventory, and AP versus sales, the bridge to CFO, and a hypothetical QoQ scorecard. Educational, not advice.

Net income can look calm while cash from operations (CFO) wobbles. The usual culprit is working capital: receivables, inventory, and payables swinging quarter to quarter. DIY investors who only read the income statement miss the cash story.

Educational only — not financial advice. All worked numbers are hypothetical. Pair with revenue quality and quarterly earnings literacy.

Direct answer

From the balance sheet, compute quarter-over-quarter changes in trade receivables, inventories, and trade payables. Relate those deltas to sales growth. Then open the cash-flow statement (IAS 7 style) and confirm how working-capital movements bridge net income to CFO. Large AR/inventory builds without matching sales growth are a quality flag; aggressive payable stretch can temporarily boost CFO.

Balance-sheet deltas explain a lot of CFO surprises. Compare ΔAR, Δinventory, and ΔAP to sales before you trust accrual earnings.

Hypothetical $ millions. Receivables and inventory rose; payables fell (cash left). Summed drag ~$38M before other CFO items — reconcile to the actual cash-flow statement.

Always reconcile to the actual CFO working-capital lines — the table above is a literacy sketch, not a substitute for the filing.
