When Profit Growth Uses Cash

Growing sales and reported profit do not guarantee stronger operating cash flow. A business may wait for customers to pay, build inventory ahead of demand, or rely on supplier credit as it expands. To assess actual earnings quality, use company-period data and reconcile profit to operating cash flow. The example below estimates only the working-capital requirement associated with added sales.

A focused estimate of incremental operating working capital is: increase in receivables + increase in inventory − increase in trade payables. Under IAS 7’s indirect method, changes in inventories and operating receivables and payables are among the adjustments used to determine operating cash flow. IAS 7 does not prescribe this day-based model. For annual reporting periods beginning on or after 1 January 2027, IFRS 18 amends IAS 7’s indirect-method starting point to operating profit or loss; earlier application is permitted.

Consider Rp1,000 million in added annual sales, a 30% contribution margin, cost of goods sold (COGS) at 70% of sales, and a 360-day year. At 45 receivable days, receivables are Rp1,000m × 45 ÷ 360 = Rp125.0m. At 60 inventory days, inventory is Rp700m × 60 ÷ 360 = Rp116.7m. At 40 payable days, trade payables are Rp700m × 40 ÷ 360 = Rp77.8m. The modeled steady-state working-capital requirement is Rp125.0m + Rp116.7m − Rp77.8m = Rp163.9m, or about Rp164m for each Rp1bn of added annual sales. Purchases are approximated by COGS, so the payable estimate is a proxy. This is an estimated balance, not a measured cash outflow.

The assumed annual contribution is Rp300m: Rp1,000m × 30%. At a 12% annual funding rate, the modeled Rp163.9m balance implies about Rp19.7m in annualized funding cost. Contribution is an annual flow; funding cost is an annualized charge on an estimated balance. Their comparison is illustrative. The Rp280.3m remaining after that modeled cost is not net profit, free cash flow, or a forecast. Fixed costs, tax, capital expenditure, credit losses, and other effects are excluded.

Timing can change the picture. A period-end balance may reflect seasonal sales, shipment timing, planned stock builds, or changed customer or supplier terms. Compare equivalent seasonal dates and monthly or quarterly trends. Separate sales-volume effects from collection speed, inventory accumulation, and changes in credit terms. Review overdue receivables and inventory quality, then reconcile balance movements to reported operating cash flow before deciding whether a funding need is structural.

Test whether collection practices, inventory planning, or customer terms can improve without harming sales or service. Longer supplier payment periods may reduce the immediate funding gap, but consider supplier capacity and continuity. Recalculate using actual margins, working-capital days, and funding rates. Beyond the numbers, decision-makers need to understand both the contribution growth earns and the cash the business must commit to support it.
