Cash and Cash-Flow

Cash is the fuel that keeps a business's engine running — and a genuinely profitable business can still stall completely if it simply runs out of fuel.

1.3.3
Builds directly on 1.3.2's profit calculations, and feeds straight into 1.3.4's sources of finance as a genuine solution.
Why cash is different from profit

The importance of cash to a business

Cash is the physical money a business has available right now, in its bank account or till, that it can spend immediately. This is genuinely different from the profit you calculated in 1.3.2 — profit is worked out over a period of time, while cash is what's actually available at this precise moment.

To pay suppliers, overheads and employees

Rent, wages and supplier invoices all need to be paid with real cash on the day they're due, whatever the business's profit figure happens to say.

To prevent insolvency

Insolvency is when a business cannot pay its debts as they fall due — a business can be forced to close for this reason alone, even while remaining profitable on paper.

Cash is not the same as profit

A business can be genuinely profitable and still run out of cash, most commonly when customers haven't paid yet or when a lot of cash has been spent on new equipment.

In the real world: Carillion, once one of the UK's largest construction and services companies, collapsed suddenly in 2018 despite having reported profits in recent years — a widely studied case showing that even a business that looks financially healthy on paper can fail if it simply doesn't have enough actual cash to keep operating day to day.
Predicting the gap before it happens

Calculation and interpretation of cash-flow forecasts

A cash-flow forecast predicts a business's cash inflows and outflows over a future period, usually broken down month by month, giving a business time to act on a problem before it actually happens.

Net cash flow = Cash inflows − Cash outflows
Closing balance = Opening balance + Net cash flow

The closing balance for one month becomes the opening balance for the next, carrying any shortfall (or surplus) forward automatically.

ItemJanuary (£)February (£)March (£)
Opening balance1,500500(500)
Cash inflows12,00012,00014,000
Cash outflows13,00013,00013,000
Net cash flow(1,000)(1,000)1,000
Closing balance500(500)500

Notice how each month's closing balance carries straight into the next month's opening balance. January starts with £1,500, but loses £1,000 in net cash flow, closing at £500. February starts from that £500, loses another £1,000, and closes negative at (£500) — shown in brackets, the standard way negative figures appear on an Edexcel exam paper. By March, higher inflows finally push net cash flow positive again, but only enough to bring the closing balance back to £500, not to erase the shortfall entirely.

Spotting this pattern in advance is exactly why forecasts matter: a manager seeing February's negative closing balance ahead of time can arrange an overdraft or loan before the shortfall actually happens, rather than being caught out by it.

Exam practice

Have a go

Standalone questions below are typical of Section A — no case study needed. The 6 and 9-mark questions are built around a Source Booklet–style case study, matching how Section B and C actually work in the real exam.

1 mark
Select one answer

Which one of the following is a cash outflow?

A. Cash received from a customer
B. A new loan paid into the business account
C. Payment made to a supplier
D. Cash received from selling an unused asset

Answer: C.

Calculate

A business has cash inflows of £10,000 and cash outflows of £7,000 this month. Calculate the business's net cash flow.

Answer: £10,000 − £7,000 = £3,000. Full marks are typically awarded for the correct final answer, though showing working is good practice.

3 marks
Explain

Explain one reason why cash is important to a business.

Structure guide: 1 mark identifying a reason, plus 2 further marks developing it — eg "Cash is needed to pay suppliers, employees and overheads (1), since these bills must be paid immediately (1), regardless of how much profit the business has made on paper (1)."

Case study — Hartley Print Co: Hartley Print Co made a healthy profit last year, but its largest client pays invoices on 60-day credit terms. This month, Hartley Print Co has an opening balance of £1,500, expects cash inflows of £12,000, and cash outflows of £14,000.
2 marks
Calculate

Using the information above, calculate Hartley Print Co's net cash flow and closing balance for the month.

Answer: net cash flow = £12,000 − £14,000 = −£2,000. Closing balance = £1,500 + (−£2,000) = −£500.

6 marks
Analyse

Analyse the impact on Hartley Print Co of its largest client's 60-day credit payment terms.

Structure guide: application (AO2) and analysis (AO3a) together — eg identify that the client doesn't pay for 60 days after a sale is made (AO2), then analyse how this delays cash actually arriving even though the sale has already boosted profit on paper, contributing directly to the negative closing balance calculated above, and meaning Hartley Print Co could struggle to pay its own suppliers and staff despite genuinely being profitable (AO3a).

9 marks
Justify

Hartley Print Co is considering two options to address this cash-flow problem: negotiating shorter payment terms with its client, or arranging an overdraft with its bank. Justify which option Hartley Print Co should choose.

Structure guide: apply knowledge to Hartley Print Co's specific situation (AO2), analyse points on both sides (AO3a) — negotiating shorter terms tackles the root cause but depends on the client agreeing, while an overdraft is more immediately within Hartley Print Co's own control but adds interest costs — then reach a clear, justified choice (AO3b).
