1.3 Size of Business – Significance of Small Businesses
Learning Objectives
Explain how business size is measured and assess the suitability of each method.
Identify the advantages and disadvantages of being a small business.
Analyse the role of small firms – especially family‑run enterprises – in the wider economy.
Describe the main internal and external growth routes for small firms and the impact of mergers, take‑overs, joint ventures and strategic alliances on stakeholders.
What is a Small Business? (Cambridge definition)
A business is classed as a small enterprise if it meets any one of the following criteria (as set out in the Cambridge IGCSE/A‑Level syllabus):
≤ 50 employees
Turnover ≤ £10 million (or the equivalent in local currency)
Balance‑sheet total ≤ £5 million
Market‑share below a defined threshold (usually < 5 %)
National thresholds may differ (e.g., EU: ≤ 250 employees), but for the syllabus only the above four criteria are required.
1.3.1 Methods of Measuring Business Size
Measurement
What it measures
Typical use
Appropriateness for SMEs
Number of employees
Work‑force size – a direct indicator of operational scale.
Useful for labour‑intensive sectors (retail, hospitality, services).
Good for comparing firms with similar labour intensity; however, it ignores capital intensity.
Turnover (sales revenue)
Total value of goods or services sold in a period.
Most common across all sectors; reflects market activity.
Provides a comparable monetary measure; may be distorted by seasonal peaks.
Balance‑sheet total (assets)
Value of the firm’s total assets at a point in time.
Important for capital‑intensive industries (manufacturing, construction).
Shows the asset base but can be misleading for service‑oriented SMEs with few tangible assets.
Market share
Proportion of total industry sales captured.
Relevant where competition is intense (telecoms, FMCG).
Helpful for assessing competitive power, but many SMEs operate in niche markets where market share is naturally low.
Value‑added
Contribution to GDP after subtracting intermediate inputs.
Used mainly in macro‑economic analysis.
Rarely calculated by individual SMEs; therefore of limited practical use for size classification.
1.3.2 Significance of Small Businesses in the Economy
SMEs account for ≈ 99 % of all enterprises in the UK and the EU.
They provide around 60 % of private‑sector employment and contribute roughly 45 % of GDP (OECD, 2023).
Over 50 % of UK patents in the last decade originated from firms with fewer than 250 employees – a key source of innovation.
Policy support (grants, tax reliefs, simplified regulation) is justified by their role in job creation, regional development and competition.
Key Characteristics of Small Businesses
Owner‑managed or family‑run
Limited access to conventional finance
High flexibility in decision‑making
Close, personal relationships with customers and suppliers
Often operate in niche or local markets
Family‑Run Small Businesses – Strengths & Weaknesses
Sharing resources (technology, distribution) to enter new markets without full acquisition.
Partners share profits and risks; employees may face new reporting lines; customers benefit from combined expertise.
Acquisition (merger or takeover)
Purchasing a competitor or complementary business to increase market share or capability.
Owners may realise a premium; employees face redundancy or integration; suppliers may gain a larger client; customers could see improved product range.
External‑finance‑driven expansion
Using venture capital, angel investment, government grants or crowdfunding to fund rapid scaling.
New investors gain equity or repayment rights; founders may dilute control; staff may benefit from growth‑related opportunities.
1.3.4 Impact of Mergers & Take‑overs on Stakeholders
Owners/shareholders: May receive a premium price or equity in the new entity; risk of loss of control if a takeover occurs.
Employees: Potential for redundancy, redeployment or new career opportunities; morale can be affected by uncertainty.
Suppliers: Larger combined firm may negotiate better terms, possibly reducing supplier margins; however, increased order volumes can benefit key suppliers.
Customers: May gain a wider product range and improved service, but could face higher prices if competition falls.
Local community: Consolidation can lead to closure of a local outlet, reducing employment, but may also bring investment and modern facilities.
1.3.5 Importance of Joint Ventures & Strategic Alliances
Allow SMEs to pool scarce resources (R&D, marketing, distribution) without full ownership transfer.
Facilitate entry into markets where a single SME would lack scale or local knowledge.
Spread risk – losses are shared, making high‑risk projects (e.g., new technology) more feasible.
Enhance innovation through knowledge‑spillovers between partners.
Stakeholder impact is generally balanced: partners share profits, employees may gain new skills, customers receive improved offerings.
Advantages of Being a Small Business
Speed of decision‑making – few hierarchical layers enable rapid response to market changes.
Close customer relationships – personal contact builds loyalty and provides immediate market intelligence.
Innovation driven by necessity – resource constraints stimulate creative problem‑solving and niche product development.
Owner motivation & commitment – direct link between effort, profit and reputation encourages high work ethic.
Access to alternative finance – micro‑finance, crowdfunding, government grants and business angels can fill the gap left by banks.
External economies of scale – clusters, shared services and knowledge spill‑overs can offset limited internal scale.
Disadvantages of Being a Small Business
Limited access to conventional finance – higher interest rates, stricter collateral requirements or outright denial of bank loans.
Higher unit costs (limited economies of scale) – smaller production runs and weaker bargaining power raise per‑unit expenses.
Vulnerability to market fluctuations – thin cash reserves and limited product diversification increase exposure to downturns.
Dependence on key individuals – loss of a founder, skilled technician or primary sales contact can disrupt operations.
Limited market power – SMEs often face higher input prices and less favourable credit terms.
Risk‑management constraints – limited resources for insurance, hedging or specialist advisory services.
Comparison: Small vs. Large Businesses
Aspect
Small Business
Large Business
Decision‑making speed
Fast – few layers of authority
Slower – multiple hierarchies & formal procedures
Access to finance
Limited; higher cost; relies on alternative sources
Broad; lower cost; can issue shares or bonds
Economies of scale
Low internal; may gain external economies via clusters
High internal (bulk buying, specialised staff) and external
Customer relationship
Personalised, high loyalty
Standardised, less personal contact
Risk exposure
High – limited buffers, concentrated revenue streams
Lower – diversified assets, larger cash reserves
Innovation approach
Necessity‑driven, niche‑focused
R&D‑intensive, often incremental
Illustrative Example: “Sweet Crumbs” Bakery
Profile: 8 employees, annual turnover £250 000. Advantage in action: After a customer suggests a gluten‑free pastry, the owner develops and launches it within one week, gaining an immediate sales boost. Disadvantage in action: To open a second shop the owner needs a £100 000 loan; banks refuse on collateral grounds. He secures a regional government grant and raises £20 000 via crowdfunding, but the expansion is delayed. Contrast with a national chain: The chain obtains financing at 3 % interest, negotiates bulk‑buying discounts, and rolls out the same gluten‑free line across 150 outlets in three months. Stakeholder impact of a potential takeover: If a larger food‑service group acquires “Sweet Crumbs”, the owner may receive a premium, employees could face redeployment, suppliers might gain larger orders, and customers could lose the boutique feel but gain wider availability.
Key Points to Remember
SMEs are the backbone of most economies – they create the majority of jobs and a substantial share of GDP.
Their agility, close customer contact and innovation driven by necessity are core competitive advantages.
Financial constraints, limited economies of scale and reliance on key individuals are the main challenges.
Family‑run SMEs add trust and cohesion but face succession and governance issues.
Growth can be organic or achieved through franchising, alliances, acquisitions or external‑finance‑driven expansion; each route has distinct stakeholder effects.
Mergers, take‑overs, joint ventures and strategic alliances reshape market structure, redistribute risk and can either enhance or threaten the contributions of small firms.
Policy measures (grants, tax relief, simplified regulation) aim to offset disadvantages and encourage sustainable growth.

Exam‑Style Question
“Discuss the advantages and disadvantages of small businesses in the context of a rapidly changing technological environment.”
In answering, candidates should:
Identify at least three advantages (e.g., speed of decision‑making, innovation driven by necessity, close customer feedback) and three disadvantages (e.g., limited finance for technology investment, vulnerability to rapid market shifts, lack of specialised IT staff).
Explain how each point influences performance, using economic terminology such as economies of scale, opportunity cost and risk exposure.
Support arguments with real‑world examples (e.g., a local retailer adopting a new e‑commerce platform versus a national chain that can invest in AI‑driven logistics).
Provide a balanced judgement on whether the advantages outweigh the disadvantages for SMEs operating in a digital age.
