Profit, Liquidity and Business Failure

The statement of comprehensive income builds profit in three stages, and Pearson's own spec wording matters here: the final line isn't called "net profit" on the syllabus, it's profit for the year (net profit), and using the exact term costs nothing while getting it wrong occasionally costs a mark on a Define question. Start with revenue and strip costs away in order: revenue minus cost of sales (what it directly cost to make or buy what was sold) leaves gross profit; gross profit minus operating expenses (rent, wages, marketing — the overheads of running the business day to day) leaves operating profit; operating profit minus interest (the cost of any borrowing) minus tax leaves profit for the year. Three profits, each one strictly smaller than the last, each answering a slightly different question about the same business.

Each of those three profits has its own margin, and the mechanism connecting a profit figure to its margin is the same every time: divide the profit by revenue and multiply by 100. gross profit margin = gross profit ÷ revenue × 100 isolates pricing and production cost alone. operating profit margin = operating profit ÷ revenue × 100 adds in how tightly overheads are controlled. profit for the year margin = profit for the year ÷ revenue × 100 adds in the cost of debt and tax on top of that. The gap between any two margins, for the same business, tells you exactly which layer of cost is eating into the money — a shrinking gap between gross and operating margin means overheads are under control; a widening one means they aren't.

"Increase profit" and "improve profitability" sound like the same instruction and are not — a confirmed, examiner-flagged confusion on this spec item (Jan 2020, Q2e). Profit is an absolute £ figure: selling more units at an unchanged price and cost per unit raises profit in a straight line without moving the margin by a single percentage point, because the numerator (profit) and the denominator (revenue) scale up together in the same ratio. Improving profitability specifically means changing the RATIO itself — cutting cost of sales as a % of revenue, cutting overheads as a % of revenue, or raising price where demand is inelastic enough that the extra revenue per unit isn't wiped out by lost volume. A method that only grows the business at an unchanged margin is a real way to raise profit and a non-answer to a profitability question.

The statement of comprehensive income measures profit over a period — a year, typically — using accrual accounting: revenue is recognised the moment a sale happens, whether or not the customer has actually handed over any cash yet. The statement of financial position (balance sheet) is the opposite kind of measurement entirely: a snapshot of what the business owns and owes at one single moment. Liquidity is read off THIS statement, not the income one — which is the entire reason profit and cash can genuinely diverge. A business can recognise a sale as revenue, and after costs as profit, on the day it happens, while the actual cash for that sale doesn't arrive for another 30 or 60 days. In the gap between those two dates, the business is exactly as profitable as its accounts say and exactly as short of cash as its bank balance says, at the same time.

Two ratios read liquidity off the statement of financial position. current ratio = current assets ÷ current liabilities asks: could this business, in principle, cover everything it owes within a year using everything it could turn into cash within a year? acid test ratio = (current assets − inventories) ÷ current liabilities asks the stricter version of the same question, with inventory removed — because inventory is the current asset furthest from being spendable cash: it still has to be sold, and then that sale still has to be paid for, before it's actually cash in the bank. A business holding most of its current assets as inventory can show a current ratio that looks reassuring while its acid test ratio — the one that actually asks "can you pay a bill due tomorrow" — tells a much tighter story. A widely used rule of thumb — stated in the January 2023 mark scheme's own indicative content for a real WBS12 liquidity question — treats a current ratio of roughly 1.5:1 to 2:1, and an acid test ratio at or above 1:1, as comfortable; a ratio below that range signals a thinner cushion for short-term debts, not an automatic crisis, and what actually counts as "comfortable" still depends on the kind of business being measured.

Spec item 2.3.3.2(b) names four specific ways to improve liquidity, and each works through a different mechanism. Selling underused assets converts something that wasn't counted in either ratio (a non-current asset) into cash, which is. Negotiating longer credit terms with suppliers delays a current liability without touching current assets at all, which raises both ratios directly. factoring sells trade receivables to a specialist factor for a discounted lump sum paid immediately — trading a slower, less certain quick asset for a faster, certain one. JIT inventory simply holds less inventory in the first place, which raises the acid test ratio by shrinking the very asset it excludes. working capital — current assets minus current liabilities — is the day-to-day pool all of this protects: too little risks missing a payment; too much is cash sitting idle that could be earning a return doing something else in the business.

Spec item 2.3.3.3 splits business failure into internal causes (inside the business's own control) and external causes (outside it), and the internal list reads almost like a checklist of what happens when the profit/cash mechanism above goes wrong in practice. Poor management of cash flow is the general failure to plan for the gap between recognising profit and receiving cash at all. Overestimation of sales commits the business to costs — inventory bought, staff hired, capacity built — against sales that don't materialise, leaving cash tied up with no matching revenue arriving to free it. Poor inventory control directly damages the acid test ratio (too much cash locked in stock) and can hit gross margin too, through waste and write-offs. Poor marketing and poor quality both hit revenue and profit first, and only become a cash problem once the shortfall has run long enough to bite.

Overtrading is the most specific and most examinable of the internal causes, because — unlike the others — it happens to businesses doing almost everything right: winning real customers, growing real sales, reporting real, rising profit throughout. What makes it dangerous is exactly the timing gap from the mechanism above, now working dynamically rather than as a single snapshot: a growing business has to buy more inventory and extend credit to more customers before its own bigger sales are collected as cash, while its own suppliers and staff still need paying on the usual schedule. The faster the growth, the larger that gap gets in absolute pounds — which is why a business can be provably profitable on its own statement of comprehensive income and still run out of cash to survive the very growth that's driving that profit.

External causes sit outside the business's control but often run through the same two channels — profit and liquidity — as everything above. A rise in interest rates, for instance, is a single economic event with two separate effects on the same business: it raises the interest line directly deducted to reach profit for the year (a profitability effect), and it simultaneously raises the cost of any overdraft or short-term loan the business relies on to fund its working capital (a liquidity effect) — the same shock, hitting the same business, through two different lines of the accounts. Exchange rates, competition, government regulation, supplier problems and natural phenomena each work through their own specific mechanism, but the same question is worth asking of every one of them: does this hit profit, liquidity, or — as with interest rates — genuinely both? Two further external causes are easy to under-name because they sound like ones already listed: market conditions means a shift in demand across an entire product category — more or fewer people wanting this KIND of product at all — a different pressure from competition (a specific rival's own pricing or product decisions), even though both can shrink the same business's sales at the same time; and the wider economy (a slowdown or recession, distinct from any single interest-rate or exchange-rate move) can depress demand and raise costs across every business in a market at once, rather than through one specific price change. A real WBS12 20-mark question built almost entirely around this distinction — Amazon's 2022 withdrawal of the Kindle e-reader from China (October 2023, Q3) — credited both market conditions (Chinese consumer demand for e-readers still growing overall, but domestic rivals iFlytek and Huawei taking share, and other Western firms such as Airbnb and Microsoft also reducing China operations) and Amazon's own internal choices (failing to adapt the Kindle to local demand, and marketing so weak that "jokes were made about not knowing the Amazon Kindle was for sale in China") as genuine, independently creditable causes of the very same business failure — exactly the internal/external split this section teaches, with both sides operating at once rather than one ruling the other out.
