What this dot point is asking

This outcome wants you to explain cash flow and the crucial difference between cash and profit, to construct and interpret a simple cash-flow forecast, and to identify ways to improve cash flow. The central idea is that a business can be profitable yet still fail if it runs out of cash, so managing the timing of money in and out is vital for survival.

The answer

Cash flow, and cash versus profit

Cash flow is the movement of money into and out of a business over time. Cash inflows include sales receipts, loans and investment; cash outflows include paying for materials, wages, rent and loan repayments.

Cash is not the same as profit. Profit is revenue minus costs over a period; cash is the actual money available right now. A firm can make a profit on paper but have no cash - for example if customers have not yet paid, or if it has spent cash buying stock or equipment. Running out of cash, even while profitable, can force a business to close. This is why liquidity (having enough cash) matters.

The cash-flow forecast

A cash-flow forecast predicts the cash coming in and going out month by month. Its key lines are:

Cash inflows - all money expected in.
Cash outflows - all money expected out.
Net cash flow = inflows minus outflows.
Opening balance = the cash at the start of the month.
Closing balance = opening balance plus net cash flow (and the next month's opening balance).

A forecast helps a firm spot a shortfall early and arrange finance, so it is essential for planning and for persuading a bank to lend.

Causes of cash-flow problems

Customers paying late (too much trade credit given).
Holding too much stock (cash tied up in unsold goods).
Spending heavily on assets at once.
Low sales or seasonal dips.
Paying suppliers too quickly.

Improving cash flow

Speed up inflows - chase debtors, reduce credit given, offer early-payment discounts.
Delay outflows - negotiate longer credit from suppliers, delay non-urgent spending.
Arrange finance - an overdraft or short-term loan to cover a gap.
Reduce stock - free cash tied up in inventory.

Many of these are short-term fixes; a lasting problem of low sales must be tackled at its root.

Worked example

A shop has an opening balance of $4,000 in January. Forecast figures are: January inflows$ 10,000, outflows $13,000; February inflows$ 14,000, outflows $11,000. Work through the cash-flow forecast and interpret it.

Step 1: January net cash flow and closing balance

Net cash flow = inflows minus outflows = $\$ 10{,}000 - \ $13{,}000 = (\$ 3{,}000) $, a net outflow. Closing balance = opening + net cash flow =$ \ $4{,}000 + (\$ 3{,}000) = \ $1{,}000$ .

Step 2: February net cash flow and closing balance

January's closing balance ( $1,000) becomes February's opening balance. Net cash flow =$ \ $14{,}000 - \$ 11{,}000 = \ $3{,}000$ , a net inflow. Closing balance = $\$ 1{,}000 + \ $3{,}000 = \$ 4{,}000$.

Step 3: Interpret the forecast

January has a net outflow that nearly empties the bank (closing $1,000), so the shop is tight on cash that month and should arrange a small overdraft as a cushion. February recovers, with inflows exceeding outflows and the balance back to$ 4,000. The forecast lets the owner see the January squeeze in advance and plan for it, rather than being caught short - the whole purpose of forecasting.

Examples in context

Example 1. A profitable firm caught short. A Singapore wholesaler wins a big order and records a healthy profit, but the customer pays 60 days later while the wholesaler must pay its own suppliers and staff now. Despite the profit, it nearly runs out of cash and needs an overdraft to bridge the gap. The case shows the classic split between profit and cash: profitable on paper, but short of cash because of the timing of payments.

Example 2. Forecasting for a seasonal business. A shop selling festive goods knows sales spike before Chinese New Year and slump afterwards. Its cash-flow forecast shows heavy outflows buying stock months ahead, then strong inflows during the festive period. By forecasting, the owner arranges finance for the stock-buying months and avoids a cash crisis. This shows how forecasting helps a seasonal firm plan around predictable cash swings.

Try this

Q1. Explain the difference between cash and profit. [2 marks]

Cue. Profit is revenue minus costs over a period of time, while cash is the actual money available to the business now; a firm can make a profit but still be short of cash if, for example, customers have not yet paid or it has spent cash on stock or assets.

Q2. A business has an opening balance of $2,000 and a net cash flow of ($ 1,500) this month. Calculate the closing balance. [2 marks]

Cue. Closing balance = opening balance + net cash flow = $\$ 2{,}000 + (\ $1{,}500) = \$ 500$.

Q3. Explain one way a business could improve its cash flow if it forecasts a shortage next month. [4 marks]

Cue. It could speed up its cash inflows by chasing customers who owe money and reducing the credit period it offers, or by giving a small discount for early payment. This brings cash in sooner, lifting the bank balance so the firm can meet its outflows on time and avoid going overdrawn. The drawback is that pressing customers too hard or discounting reduces revenue slightly, so it is often a short-term measure alongside tackling the underlying cause.

Exam-style practice questions

Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

Original4 marksA business starts a month with

5,000 in the bank. During the month it receives

12,000 cash inflow and pays out $15,000 cash outflow. Calculate the net cash flow and the closing balance.

Show worked answer →

Net cash flow = total cash inflows minus total cash outflows = $12,000 -$ 15,000 = ( $3,000), a net outflow of$ 3,000.

Closing balance = opening balance + net cash flow = $5,000 + ($ 3,000) = $2,000.

So the business ends the month with $2,000 in the bank, having spent$ 3,000 more than it received during the month.

What markers reward: net cash flow as inflows minus outflows (correctly shown as a negative or outflow), and the closing balance as opening balance plus net cash flow.

Original6 marksA small retailer forecasts a negative closing cash balance next month. Analyse two actions it could take to improve its cash flow.

Show worked answer →

Action 1 - speed up cash inflows. The retailer could ask customers to pay sooner (for example offer a small discount for early payment, or reduce credit terms), bringing cash in faster and lifting the bank balance.

Action 2 - delay or reduce cash outflows. It could negotiate longer credit terms with suppliers (pay later), delay non-urgent spending, or arrange an overdraft to cover the gap, easing the outflow this month.

Develop the chain: the aim is to raise inflows or cut or delay outflows so the closing balance stays positive; many measures are short-term fixes, and the underlying cause must still be addressed.

What markers reward: two practical, correctly explained actions (speed up inflows, delay or cut outflows, arrange finance), applied to the retailer, with a chain linking the action to a better balance.
