Understanding the Relationship Between Working Capital and Business Growth

Vinu: Manu, a business may report growing sales and profits, yet still face a cash shortage. How does that happen?

Manu: Because business growth normally requires additional working capital. When sales increase, the business must purchase more raw materials, maintain higher inventory and offer more credit to customers. Cash gets blocked in these current assets before it is collected from customers.

Vinu: What exactly is working capital?

Manu: Net working capital is the difference between current assets and current liabilities.

Working Capital = Current Assets − Current Liabilities

Current assets include inventory, receivables and cash. Current liabilities include trade creditors, short-term borrowings and other liabilities payable within a year.

Vinu: Can you explain its connection with growth through an example?

Manu: Consider a manufacturing company with annual sales of ₹5 crore. It maintains inventory equal to 60 days of sales and allows customers 45 days’ credit. Suppliers provide 30 days’ credit.

If sales increase to ₹8 crore, the company must maintain more inventory and carry higher receivables. Unless supplier credit also increases proportionately, the additional amount has to be funded through internal accruals, promoter contribution or bank finance.

Vinu: So higher sales automatically mean a higher working capital requirement?

Manu: Generally, yes. But the increase depends on the operating cycle and the efficiency of working capital management. A business with fast inventory movement and quick customer collections may grow without a proportionate rise in borrowing.

Vinu: What is the operating cycle?

Manu: It is the time taken to convert cash invested in operations back into cash:

Cash → Raw Materials → Finished Goods → Sales → Receivables → Cash

The longer this cycle, the greater the working capital requirement.

Vinu: Suppose a business grows too quickly. What problems can arise?

Manu: Rapid growth without adequate working capital can result in:

Delayed payments to suppliers

Excessive use of cash credit limits

Cheque or instalment defaults

Inability to purchase sufficient materials

Delays in production and customer delivery

Dependence on costly short-term borrowing

This situation is called overtrading—the business generates sales beyond the level its financial resources can safely support.

Vinu: Can a profitable business fail because of this?

Manu: Certainly. Profit does not immediately mean cash. A sale may be recorded today, but the customer may pay after 60 or 90 days. Meanwhile, wages, electricity, taxes and supplier payments must be met. A profitable business can therefore face serious liquidity problems.

Vinu: What should a banker examine when a borrower seeks finance for business growth?

Manu: The banker should examine:

Historical and projected sales

Inventory holding period

Receivables collection period

Credit available from suppliers

Working capital cycle

Existing utilisation of bank limits

Cash-flow projections

Promoter’s contribution

Reasonableness of the growth assumptions

The banker must confirm that the projected turnover is achievable and that the requested limit is supported by the resulting working capital gap.

Vinu: Should long-term assets be financed from working capital?

Manu: No. Machinery, buildings and major expansion expenditure should normally be financed through long-term sources such as term loans, equity or retained earnings. Using cash credit to purchase fixed assets creates a permanent shortage in working capital.

Vinu: How can a growing business control its working capital requirement?

Manu: It can:

Reduce slow-moving inventory

Improve production planning

Collect receivables faster

Fix customer-wise credit limits

Negotiate better credit terms with suppliers

Use advances or milestone billing

Match borrowing tenure with the purpose

Prepare regular cash-flow forecasts

Vinu: Is having very high working capital always good?

Manu: Not necessarily. Excessive working capital may indicate idle cash, overstocking or poor collection of receivables. Inadequate working capital creates liquidity pressure, while excessive working capital reduces profitability. The objective is to maintain an optimum level.

Vinu: What is the main relationship between working capital and sustainable business growth?

Manu: Working capital is the financial fuel that supports day-to-day growth. Sales can expand sustainably only when inventory, receivables and operating expenses are properly funded. Growth without adequate working capital creates liquidity stress, while efficient working capital management allows the business to grow with better cash flow and lower borrowing.

Vinu: So growth should be planned along with finance, not merely with sales targets?

Manu: Exactly. A business should ask not only, “How much can we sell?” but also, “How much additional money will be blocked before those sales are converted into cash?” That answer determines whether the proposed growth is financially sustainable.
