Working Capital: Why Profitable Firms Run Out of Cash

Profitability and liquidity are not the same thing. A fast-growing company can consume more cash because of receivable and inventory financing. The cash conversion cycle makes that visible.

Why can a company report a profit in its income statement and still find no money in its bank account? The most common answer is working capital. The sale may have been made but not collected; inventory may have been bought for production; the supplier may have been paid before the customer paid. The gap between those three timings is what creates the funding requirement.

A simple example

Suppose a company holds inventory for 70 days, collects from customers in 65 days and pays suppliers in 45 days. The cash conversion cycle is 90 days. In other words, the company has to carry roughly three months of financing through the production and sales cycle from its own cash or from bank facilities.

If sales grow 30% while the CCC stays the same, the working capital requirement usually grows too. Rapid growth does not always generate cash; in the early stages it often consumes it.

Which lever sits where?

How does a credit committee read this data?

The bank wants to see whether a working capital facility is tied to a self-liquidating cycle. Persistently rising inventory, uncollectable receivables or short-term credit used to finance fixed assets all raise credit risk. Explaining the working capital requirement with a formula and a movement table therefore builds confidence in a credit request.

Four reports for management

• Receivables ageing: 0–30 / 31–60 / 61–90 / 90+ days.
• Inventory ageing and a list of slow-moving products.
• Supplier terms and concentration among critical suppliers.
• The CCC trend: against budget, last year and the sector or company target.

Working capital financing should not start with “getting a bigger limit from the bank”. First find where the cash is being tied up, separate what operational improvement can fix from what genuinely needs funding, and then finance the remaining structural requirement with the right product and tenor.

Why does growth turn into a working capital crisis?

If sales grow 30% while the terms given to customers stay the same, receivables grow by roughly the same proportion. If safety stock levels are rising or supplier terms are shortening, the cash requirement of growth can outpace the increase in revenue. The growth budget therefore has to be prepared alongside a funding requirement budget.

Putting a money figure on the opportunity

A 5-day improvement in DSO or DIO should not be an abstract KPI. The approximate cash effect can be calculated and tied to departmental targets. Annual credit sales / 365 × the days of improvement, for example, gives a crude but powerful first estimate of the cash that could be released on the receivables side.

Segmentation: different rules rather than one policy

Customers should be segmented by payment behaviour and strategic value; inventory by turnover speed, margin and criticality; suppliers by substitutability and operational risk. Applying the same terms or the same inventory target to every segment can break the operation.

A 90-day working capital sprint

1. Data cleaning and baseline in the first 2 weeks
2. Customer, SKU and supplier segmentation in weeks 3–4.
3. Implementation of collection, inventory and purchasing actions in weeks 5–8.
4. Cash effect, sustainable KPIs and governance in weeks 9–12.

The effect on financing cost

Cash released from working capital can reduce borrowing and interest expense. The ROI of the project should therefore be measured not only by the size of the cash released but together with the fall in financing cost and the improvement in operational risk.

Behavioural segmentation in receivables management

Customers should be separated by payment behaviour, not by turnover alone. Segments such as “always on time”, “systematically 10–20 days late”, “only after a reminder” and “high dispute rate” change the collection strategy. The same contractual term produces a very different real cash term across different customers.

The financial and operational optimum in inventory

Taking inventory to a minimum is not always right. Critical raw materials, long lead times or a high stockout cost may require more safety stock. But slow-moving or obsolete inventory ties up cash while carrying the risk of losing value. Turnover speed, margin, lead time and criticality should therefore be assessed together at SKU level.

The limit on extending supplier terms

Increasing DPO generates cash in the short term; but if a critical supplier raises prices, moves to payment in advance or restricts shipments, the total economic cost rises. Term negotiation, supplier segmentation and purchase price have to be handled together.

The working capital cockpit

Tying these indicators to a bonus system needs care. If the sales team is rewarded on turnover alone, growth can be encouraged at the expense of long terms and weak collection. Revenue quality and cash conversion have to be balanced against commercial targets.
