How cash flow, working capital, credit, inventory, receivables, payables, and cash cycles affect liquidity.
Working capital is the link between operations and liquidity. A profitable entity can still run out of cash if receivables are collected too slowly, inventory ties up funds, payables are paid too quickly, or growth increases the cash investment cycle.
Study this page as a cash-timing lesson. The Core 2 answer should identify the working-capital driver, quantify the cash effect when possible, and recommend an action that protects liquidity without damaging supplier relationships, customer value, or operations.
Finance is a moderate Core 2 emphasis. Working-capital questions test whether the candidate can identify the cash-timing driver, quantify the effect when possible, and recommend an action that preserves operations and relationships.
| Coverage area | Core 2 question |
|---|---|
| Cash timing | Do inflows, outflows, minimum balances, and financing availability meet operating needs? |
| Working-capital driver | Are receivables, inventory, payables, credit terms, or bank balances creating the cash issue? |
| Policy effect | How do credit, inventory, or supplier-payment policies change cash tied up in operations? |
| Problem type | Is the issue timing, permanent financing, or weak profitability? |
| Recommendation | What collection, inventory, payable, financing, or cash-management action improves liquidity without damaging relationships? |
The cash investment cycle shows how long cash is tied up in receivables and inventory after considering supplier credit.
\[ \text{Cash conversion cycle} = \text{Days inventory outstanding} + \text{Days sales outstanding} - \text{Days payables outstanding} \]
| Component | What it shows | Management action |
|---|---|---|
| Days sales outstanding | How quickly customers pay. | Tighten credit, improve collections, offer discounts carefully, or review customer risk. |
| Days inventory outstanding | How long inventory sits before sale or use. | Improve forecasting, reduce obsolete stock, adjust order quantities, or negotiate supplier lead time. |
| Days payables outstanding | How long the entity takes to pay suppliers. | Use supplier terms without damaging relationships or discounts. |
| Cash balance | Whether operating needs and minimum reserves are met. | Use cash forecast, line of credit, financing, or spending controls. |
Classify the issue before recommending.
| Signal | Likely problem | Better response |
|---|---|---|
| Cash shortage despite profitable operations. | Working-capital timing. | Analyse receivables, inventory, payables, and growth-related cash needs. |
| Losses and negative cash flow persist. | Profitability or business model problem. | Address margins, costs, pricing, demand, or strategy before relying on short-term financing. |
| Seasonal cash pressure. | Timing and forecast issue. | Arrange seasonal financing and align collections, inventory, and purchases. |
| High growth consumes cash. | Working-capital investment need. | Forecast cash, revise credit terms, negotiate supplier terms, or finance growth. |
| Covenants or debt service cannot be met. | Financing and solvency issue. | Consider financing restructuring, cost actions, or slower investment. |
Working-capital policies affect cash, risk, and relationships.
| Policy change | Cash effect | Risk or trade-off |
|---|---|---|
| Tighten customer credit. | Faster collections and lower bad debts. | May reduce sales or strain customer relationships. |
| Offer early-payment discount. | Faster cash inflow. | Reduces margin and may be unnecessary for customers who would pay anyway. |
| Reduce inventory levels. | Frees cash. | May cause stockouts, lost sales, or service problems. |
| Extend supplier payment. | Preserves cash temporarily. | May lose discounts, damage supplier trust, or breach terms. |
| Use line of credit. | Covers timing gap. | Adds interest cost and covenant or renewal risk. |
| Formula | Use |
|---|---|
| \(\text{DSO} = \frac{\text{Average receivables}}{\text{Credit sales}} \times 365\) | Collection speed. |
| \(\text{DIO} = \frac{\text{Average inventory}}{\text{Cost of sales}} \times 365\) | Inventory holding period. |
| \(\text{DPO} = \frac{\text{Average payables}}{\text{Purchases or cost of sales}} \times 365\) | Supplier-payment timing. |
| \(\text{Working capital} = \text{Current assets} - \text{Current liabilities}\) | Short-term resource cushion. |
| Step | Question | Output |
|---|---|---|
| 1. Liquidity issue | What cash or working-capital pressure appears? | Timing, growth, collection, inventory, payable, or financing issue. |
| 2. Driver | Which component of the cash cycle creates the pressure? | Receivables, inventory, payables, cash balance, or debt service. |
| 3. Calculation | What is the cash or timing effect? | DSO, DIO, DPO, working capital, or forecast impact. |
| 4. Trade-off | What relationship, margin, risk, or operational issue follows? | Qualitative constraint. |
| 5. Recommendation | What action should management take and monitor? | Working-capital action plus KPI. |
| Pitfall | Correction |
|---|---|
| Treating profit as proof of liquidity. | Check cash timing and working-capital investment. |
| Recommending slower supplier payment without trade-off. | Consider discounts, terms, reputation, supply risk, and relationship. |
| Cutting inventory without service analysis. | Assess stockouts, lead time, demand variability, and customer impact. |
| Tightening credit without sales impact. | Consider customer retention and competitive terms. |
| Confusing short-term timing with long-term financing need. | Classify timing, profitability, and solvency separately. |
