Cash flow: core idea

· Cash flow = the movement of cash into and out of a business over time.
· A business can be profitable but still run out of cash. This is why cash flow and profit are not the same.
· In exams, always focus on whether the business can meet short-term payments such as wages, rent, suppliers, loan interest, and utilities.
· Weak cash flow creates liquidity problems and can lead to insolvency even when sales are strong.

Profit vs cash flow

· Profit = revenue − total costs over a period. It is an accounting measure.
· Cash flow = actual cash received and paid out in a period.
· A business can make profit but have negative cash flow if customers buy on credit, if too much cash is tied up in inventory, or if large payments must be made now.
· A business can have positive cash flow but low profit temporarily if it sells an asset, takes a loan, or delays payments.
· Exam point: profit measures success, but cash flow measures survival.

Working capital

· Working capital = current assets − current liabilities.
· Current assets usually include cash, inventory/stock, and trade receivables (debtors).
· Current liabilities usually include trade payables (creditors), overdrafts, and short-term debts due within one year.
· Positive working capital usually means the business has a better buffer to meet day-to-day expenses.
· Low or negative working capital increases the risk of cash flow problems.
· In calculation questions, show the formula clearly and state what the result suggests about short-term financial health.

Liquidity position

· Liquidity = the ability of a business to pay its short-term debts on time.
· A strong liquidity position means the business can cover its immediate commitments without serious difficulty.
· A weak liquidity position means there may not be enough readily available cash to pay bills when due.
· Cash flow forecasts, working capital, and liquidity ratios all help judge liquidity.
· Exam link: if a business has slow debtor collection, high inventory, or large short-term repayments, liquidity usually worsens.
· Always distinguish liquidity from profitability: a business may be profitable but still illiquid.

Cash flow forecasts

· A cash flow forecast predicts future cash inflows and cash outflows over a given period.
· Main purpose: identify when the business may face a cash shortage and plan ahead.
· Common inflows: cash sales, receipts from debtors, capital introduced, loans, sale of assets.
· Common outflows: wages, rent, stock purchases, utilities, marketing, loan repayments, interest.
· Key formulas:
· Net cash flow = total cash inflows − total cash outflows
· Closing balance = opening balance + net cash flow
· A negative closing balance shows a likely cash deficit and signals a need for action.
· Forecasts are useful for planning, loan applications, budgeting, and decision-making, but they are only as good as the accuracy of assumptions.

How to interpret a cash flow forecast in exams

· Look for months with negative net cash flow and, more importantly, negative closing balance.
· Identify the likely cause: seasonal sales, high start-up costs, slow customer payment, heavy inventory buying, or loan repayments.
· Comment on the consequence: possible overdraft need, delayed payments, lower ability to invest, or risk of insolvency.
· Make a judgement using the trend: is the position temporary or persistent? A single bad month is less serious than repeated negative balances.
· Strong answers use both calculation and interpretation, not just one.

Relationship between investment, profit and cash flow

· Investment in non-current assets often causes an immediate cash outflow.
· In the short term, investment can reduce cash flow because the business pays now.
· In the longer term, successful investment can increase efficiency, sales revenue, and profit.
· So the relationship is often: cash flow falls first, then profit may rise later if the investment works.
· This is why fast-growing businesses often experience cash flow pressure even when expected future profits are strong.
· Exam application: expansion, new equipment, extra stock, and opening a new branch often worsen short-term cash flow before benefits appear.

This visual supports the idea that businesses manage both short-term operating cash flow and longer-term investment cash flow. It is helpful when explaining why growth and investment can put pressure on cash before profits improve. Source

Strategies for dealing with cash flow problems

· Improve cash inflows faster: reduce the credit period given to customers, chase late payments, offer discounts for early payment, or increase cash sales.
· Delay cash outflows where possible: negotiate longer credit terms with suppliers or spread payments over time.
· Use short-term finance such as an overdraft to cover temporary gaps.
· Sell unused assets or use sale and leaseback to raise cash.
· Cut or postpone non-essential spending such as expansion, equipment purchases, or discretionary marketing.
· Improve stock control so less cash is tied up in inventory.
· Review pricing, promotion, and operations to increase sales revenue, but avoid harming long-term profitability just to solve a short-term problem.
· In evaluation questions, discuss both the benefit and risk of each strategy, for example overdrafts improve liquidity but increase interest costs.

Common exam traps

· Do not confuse net cash flow with closing balance.
· Do not say a profitable business is automatically safe; it may still face liquidity problems.
· Do not assume all negative cash flow is bad; it may be caused by planned investment.
· Do not forget that credit sales raise revenue and profit before cash is actually received.
· In AO3/AO4 answers, always link your point back to the specific business context in the question.
