📖 What Is Cash Flow?
Cash flow is the movement of money in and out of a business. It is different from profit — a business can be profitable on paper but still fail because it doesn't have cash available when bills need to be paid.
Cash flow is the movement of money into and out of a business over a period of time.
Cash inflows are money coming INTO the business (e.g. sales revenue, loans received).
Cash outflows are money going OUT of the business (e.g. rent, wages, supplier payments).
Net cash flow = Total Inflows − Total Outflows
⚠️ Profit ≠ Cash — The Critical Difference
This is the most important concept on this page. A business can be profitable but still run out of cash. How?
- A business sells £50,000 of goods on 60-day credit — revenue is recorded but cash hasn't arrived yet
- Meanwhile, it must pay wages, rent and suppliers this week
- Without cash in the bank, it cannot pay these bills — even though it's technically profitable
- This is called a cash flow problem — and it can force profitable businesses to close
💸 Cash Inflows and Outflows
Every transaction that moves money in or out of the business affects cash flow. Know the key examples of each.
📥 Cash Inflows
- Cash sales — customers paying immediately
- Payments from debtors — customers who bought on credit finally paying
- Bank loans received
- Owner's capital — money invested by the owner
- Sale of assets — selling equipment or property
- Government grants
- Interest received on savings
📤 Cash Outflows
- Wages and salaries
- Rent and mortgage payments
- Payments to suppliers
- Utility bills (gas, electricity, water)
- Loan repayments
- Tax payments
- Purchase of equipment
- Marketing and advertising costs
Net Cash Flow = Total Cash Inflows − Total Cash Outflows
A positive net cash flow means more came in than went out — the business's cash balance increases.
A negative net cash flow means more went out than came in — the cash balance falls.
📋 Cash Flow Forecasts
A cash flow forecast is a prediction of future inflows and outflows. It helps a business plan ahead and avoid running out of cash.
A cash flow forecast is a document that predicts the cash inflows and outflows of a business over a future time period (usually monthly). It shows the expected opening balance, net cash flow, and closing balance for each period.
📊 How to Read a Cash Flow Forecast
| Item | January £ | February £ | March £ |
|---|---|---|---|
| CASH INFLOWS | |||
| Sales Revenue | 4,000 | 5,500 | 6,200 |
| Loan Received | 3,000 | 0 | 0 |
| Total Inflows | 7,000 | 5,500 | 6,200 |
| CASH OUTFLOWS | |||
| Rent | 1,500 | 1,500 | 1,500 |
| Wages | 2,000 | 2,000 | 2,000 |
| Suppliers | 1,800 | 2,200 | 2,400 |
| Other Costs | 500 | 500 | 500 |
| Total Outflows | 5,800 | 6,200 | 6,400 |
| Net Cash Flow | +1,200 | −700 | −200 |
| Opening Balance | 500 | 1,700 | 1,000 |
| Closing Balance | 1,700 | 1,000 | 800 |
Closing Balance = Opening Balance + Net Cash Flow. The closing balance of one month becomes the opening balance of the next.
💡 Why Use a Cash Flow Forecast?
- Identifies months when cash flow will be negative — before it happens
- Allows the business to arrange a bank overdraft or loan in advance
- Helps plan when to make large purchases
- Required by banks when applying for a loan
- Gives investors confidence that the business understands its finances
⚠️ Cash Flow Problems and Solutions
Cash flow problems are common — especially for new or seasonal businesses. The exam often asks you to identify causes and suggest solutions.
🔴 Common Causes of Cash Flow Problems
- Slow-paying customers (debtors) — customers buying on credit but taking too long to pay
- Seasonal demand — e.g. a garden centre has high summer sales but must pay costs year-round
- Overtrading — growing too fast, spending on new stock/staff before receiving payment
- Unexpected costs — equipment breaking down, emergency repairs
- Over-investment in stock — too much cash tied up in unsold inventory
- Poor financial planning — not forecasting and preparing for cash shortfalls
Solutions to Cash Flow Problems:
🏦 Arrange a Bank Overdraft
An overdraft allows the business to spend more than its current balance, up to an agreed limit. It's flexible and only charged when used — ideal for short-term cash shortfalls.
💳 Negotiate Better Payment Terms
Ask customers to pay faster (e.g. within 14 days instead of 60) and ask suppliers for longer to pay. This improves the timing of cash flows without changing profit.
💰 Obtain a Short-Term Loan
A bank loan provides a lump sum of cash to cover a shortfall. Interest must be paid, but it buys time for the business to generate more revenue.
📦 Reduce Stock Levels
Selling existing stock rather than buying more frees up cash. Just-in-time stock management prevents too much cash being tied up in inventory.
✂️ Cut Non-Essential Costs
Reducing or delaying non-essential spending (e.g. postponing marketing campaigns, delaying equipment upgrades) reduces cash outflows in the short term.
🤝 Invoice Factoring
A specialist company buys the business's unpaid invoices for an immediate cash payment (typically 80–90% of the invoice value). The factor collects payment from the customer directly.
🏢 Cash Flow in Real Business
These examples show how cash flow problems occur in reality — and how businesses deal with them.
🌸 Case Study: A Seasonal Florist
Bloom & Co is a florist with highly seasonal trade. Consider their cash flow challenge:
- February: Huge inflows from Valentine's Day — cash surplus of £8,000
- March–June: Moderate trade, manageable cash flow
- July–September: Very quiet — cash outflows (rent, wages) exceed inflows
- November–December: Christmas trade restores cash position
- The problem: fixed costs (rent, wages) continue through quiet months but inflows dry up
✅ Solution: Arrange a seasonal overdraft facility with the bank ahead of the quiet period. Save surplus cash from peak months to fund quiet months.
🏗️ Case Study: Construction Company Cash Crisis
BuildFast Ltd won a £500,000 contract but nearly went bust. Why?
- They bought materials and hired workers immediately — large cash outflows
- The contract only paid on completion — cash inflow was 6 months away
- After 3 months they had spent £180,000 but received £0 in payment
- They couldn't pay wages — staff threatened to leave
- Solution: Negotiated stage payments with the client — 25% upfront, 25% at each milestone
✅ Stage payments are a common solution for businesses with long contracts — they improve cash timing without affecting the contract value.

10 questions on Cash Flow — including forecast calculations!
✍️ Exam Tips & Mark-Scheme Gold
Cash flow questions regularly appear in Paper 1 — often including a forecast to read or complete.
⚠️ Common Mistakes
- Confusing cash flow with profit — they are NOT the same thing
- Getting the closing balance formula wrong — it's Opening Balance + Net Cash Flow
- Saying a business with negative net cash flow is "making a loss" — it might still be profitable
- Only suggesting one solution to a cash flow problem — always suggest and evaluate multiple options
- Not explaining WHY a solution helps — just naming it isn't enough
Net Cash Flow = Total Inflows − Total Outflows
Closing Balance = Opening Balance + Net Cash Flow
Opening Balance (Month 2) = Closing Balance (Month 1)
Memorise these — they appear in almost every cash flow question.
If asked to complete a forecast table, work through it systematically: (1) add up all inflows, (2) add up all outflows, (3) calculate net cash flow, (4) add net cash flow to opening balance to get closing balance. Show all workings.
For 6-mark questions about improving cash flow, always discuss the trade-offs. E.g. "An overdraft provides immediate access to cash, however it charges interest which increases the business's costs. A better long-term solution would be to renegotiate payment terms with customers to improve cash timing."
📝 Model Answer
Question: "Explain one way a business could improve its cash flow." (3 marks)
"A business could improve its cash flow by negotiating shorter payment terms with customers (1), which means cash inflows arrive sooner after each sale rather than being delayed for weeks or months (1), which could result in the business having enough cash to pay its bills on time and avoid the risk of insolvency. (1)"
