Business Planning & Expansion
Why Plan?
A business plan is a written document that sets out what a business will do, who its customers are, and how it expects to make money. It forces entrepreneurs to think before they spend — to answer hard questions about whether an idea actually makes financial sense. Banks, investors and landlords want to see a plan before they commit. Even an established firm updates its plan when it launches a new product. The discipline of writing the plan often matters more than the document itself: it exposes flawed assumptions early, while they are cheap to fix.
What Goes in a Plan
Typical sections include the business idea and aims, the target market, a marketing plan, an operations plan, details of management and staff, and financial forecasts — including costs, revenue and a cash-flow forecast. Plans aren’t just about raising finance. They help set objectives, guide decisions and track progress. The drawbacks: plans take time to write, are based on predictions that may be wrong, and can give false confidence if markets move unexpectedly (as many did during Covid).
Business plans help secure finance, set objectives, guide decisions and reduce risk — but they cost time to write, rely on forecasts that can go wrong, and risk going out of date quickly. Note you are not expected to write a plan in the exam — only to explain its purpose.
Financial Terms You Must Know
Fixed costs do not change when output changes. Rent on a bakery unit is the same whether you bake 100 loaves or 1,000. Variable costs change with output — double the loaves and you double the flour. Total costs equal fixed plus variable costs. Revenue is price multiplied by quantity sold. Profit is revenue minus total costs; if costs exceed revenue, the business makes a loss.
A quick worked example: a bakery sells 1,000 loaves at £2 each. Revenue = £2,000. Variable costs are 60p per loaf (= £600). Fixed costs are £900 per month. Total costs = £1,500. Profit = £500. Increase output to 1,500 loaves and variable costs rise to £900, but fixed costs stay at £900 — spreading the fixed cost over more loaves lowers the average cost per loaf.
Methods of Growth
Once a business is stable, owners often want to grow. There are two broad paths. Organic growth means growing under your own steam — opening new stores, expanding online, outsourcing non-core tasks, or signing up franchisees. Greggs has grown organically from a single Newcastle shop to over 2,500 UK sites. External growth means combining with another business — a merger joins two firms as equals, while a takeover sees one firm buy another outright. Morrisons’ 2004 takeover of Safeway brought it 479 extra stores overnight.
Franchising is a fast route to organic growth: the franchisor (e.g. Subway) lets a franchisee open a branded outlet in return for set-up fees and a share of revenue. The franchisee puts in the capital, the franchisor keeps tight control over the brand. Many McDonald’s in the UK are franchised. E-commerce has opened up another route — ASOS grew globally without opening any shops at all, using the internet to reach customers in more than 200 countries.
Organic growth is slower but cheaper and safer — the owners know each new shop because they opened it. External growth is faster but riskier: it is easy to overpay for a rival, and merging two different cultures often fails (the AOL–Time Warner merger is the classic cautionary tale). External growth can also trigger redundancies as duplicate roles are cut, damaging staff morale across both firms.
Economies of Scale
Economies of scale happen when growing output reduces the average cost per unit. Two main types appear in the specification. Purchasing economies — a large supermarket like Tesco buys milk in such huge volumes that suppliers give it a discount. Technical economies — a large factory can afford specialist machinery that a small workshop cannot. Both push down the average cost of making each product, which allows the business to cut prices, raise profit margins, or invest the difference back into the firm.
Diseconomies of Scale
Diseconomies of scale happen when growing further starts to raise average costs rather than lower them. The usual causes: poor communication (head office and shop floor lose touch), coordination issues (too many layers of management, slow decisions) and reduced staff motivation (workers feel like a number in a huge workforce). Many retailers — including parts of Marks & Spencer in the 2010s — hit diseconomies once they expanded too quickly. A strong answer recognises that growth and efficiency are not automatic: scale can hurt as well as help.
Average unit cost = total costs ÷ units produced. Economies of scale push this figure down; diseconomies push it up. Growth is only valuable if the average unit cost keeps falling — otherwise the extra sales cost too much to make.
A small bakery has total costs of £1,500 and produces 1,000 loaves. Average unit cost = 1,500 ÷ 1,000 = £1.50 per loaf. If output rises to 2,000 loaves and total costs rise only to £2,400 (thanks to bulk flour discounts), average unit cost falls to £2,400 ÷ 2,000 = £1.20 per loaf. That 30p saving per loaf is the economy of scale. If the bakery grows further and the owner can no longer oversee quality, wastage rises, total costs climb to £4,500 for 3,000 loaves, and average unit cost rises to £1.50 again — a diseconomy of scale.
