1.3 Size of Business – Significance of Small Businesses
Learning Objective
Students will be able to:
Explain how business size is measured.
Evaluate why small businesses are important to the national and global economy.
Analyse the ways in which small firms grow – both organically and through external transactions – and assess the impact of growth on stakeholders.
Key Definitions
Small Business: An enterprise that typically employs fewer than 50 people and has an annual turnover below a jurisdiction‑specific threshold (the exact limit varies by country).
Micro‑enterprise: A subset of small businesses with fewer than 10 employees.
Medium‑sized Business: Employs between 50 and 249 people (EU definition) or falls within the next tier of turnover.
Family‑owned Small Business: A small firm where ownership and control are held by members of the same family, often passed from one generation to the next.
1.3.1 Measurements of Business Size
Three principal criteria are used to classify business size. No single measure is perfect; the choice depends on the analytical purpose and the sector under study.
Measure
Typical Thresholds (illustrative)
Most Useful For
Key Limitations
Number of Employees
Micro ≤ 9, Small 10‑49, Medium 50‑249, Large ≥ 250
Assessing labour‑market impact; eligibility for government schemes.
Ignores capital intensity; part‑time vs. full‑time not distinguished.
Annual Turnover (Revenue)
Country‑specific – e.g., UK: Small ≤ £10 m, Medium ≤ £50 m
Evaluating market share, fiscal contribution, and tax policy.
Turnover can be volatile; high‑tech firms may have low turnover but high value.
Asset Value (Balance‑sheet total)
EU: Small ≤ €10 m, Medium ≤ €43 m
Assessing credit risk, investment capacity, and collateral availability.
Asset‑heavy industries appear larger than service‑based firms with similar output.
When each measure is most appropriate:
Employees: Best for studies of employment creation, labour‑market policy, and eligibility for SME support programmes.
Turnover: Preferred when analysing market dominance, tax revenue, or sector‑wide sales trends.
Assets: Useful for banks and investors assessing creditworthiness or the capacity to fund expansion.
Note: The thresholds shown are illustrative (UK/EU). Teachers should replace them with the figures relevant to the country or region being studied.
1.3.2 Significance of Small Businesses
Why Small Businesses Matter (syllabus focus)
Small businesses are a cornerstone of most economies because they:
Generate a large share of total employment.
Drive innovation through niche product development and rapid experimentation.
Promote balanced regional development by locating in rural or peripheral areas where large firms are scarce.
Contribute disproportionately to GDP relative to their numbers, especially when micro‑ and small firms are aggregated.
Advantages (Strengths)
High agility – quick decision‑making and rapid response to market changes.
Close customer relationships, enabling personalised service and fast feedback loops.
Lower overheads and capital requirements compared with large firms.
Ability to specialise and serve niche markets unattractive to larger competitors.
Strong contribution to employment, innovation and regional development.
Disadvantages (Weaknesses)
Limited access to finance and credit; reliance on personal savings, micro‑loans or informal sources.
Vulnerability to economic downturns and market shocks because of thin profit margins.
Regulatory and compliance burdens can represent a disproportionate cost.
Difficulty attracting, training and retaining skilled staff; higher turnover rates.
Scale economies are harder to achieve, leading to higher unit costs.
Family‑Owned Small Businesses – Strengths & Weaknesses
Strengths
Strong trust and commitment among owners, often translating into high employee morale.
Long‑term orientation – decisions are made with future generations in mind.
Deep local knowledge and strong community ties, enhancing brand loyalty.
Weaknesses
Succession‑planning problems – reluctance or difficulty in handing over control.
Potential for family conflicts to affect business decisions.
Limited external expertise and professional management, which may hinder growth.
Role of Small Firms within the Industrial Structure
Concentration in the service sector (retail, hospitality, personal services) where labour intensity favours small‑scale operations.
Presence in manufacturing as niche suppliers of specialised components, forming critical links in larger firms’ supply chains.
Contribution to the “long tail” of the economy – a large number of small, diverse firms that collectively provide a wide range of products and services.
Facilitate regional diversification by operating in rural or peripheral areas where large firms are less likely to locate.

Economic Impact – Quantitative Example
Assume a country’s total employment is 20 million. Using the table above:
$$\text{Jobs from small businesses (micro + small)} = 20\,\text{million} \times \frac{23\% + 31\%}{100} = 10.8\,\text{million}$$
More than half of all jobs are supplied by firms with fewer than 50 employees, underscoring their pivotal role in the labour market.
Potential redundancies, cultural integration challenges, or new career pathways.
Suppliers
Steady order volumes; stronger relationships over time.
Renegotiated contracts; possible concentration of purchasing power.
Customers
Improved service through better processes; continuity of brand.
Broader product range but risk of reduced personal touch.
Community
Enhanced local employment and social ties.
Potential loss of local identity; possible increased investment.
Why a Merger or Takeover May (or May Not) Achieve Its Objectives
Potential Benefits: Economies of scale, expanded market reach, access to new technologies, diversification of risk.
Key Risks: Cultural incompatibility, overestimation of synergies, integration costs, regulatory hurdles, loss of focus on core activities.
Success Factors: Clear strategic rationale, thorough due‑diligence, effective post‑merger integration plan, and alignment of stakeholder interests.
Importance of Joint Ventures & Strategic Alliances
Joint Venture (JV): Two firms create a separate legal entity to share risk and reward on a specific project. Example: A UK bakery partners with a coffee‑roasting company to launch a co‑branded café chain.
Strategic Alliance: Firms cooperate without forming a new entity, often to share technology or distribution networks. Example: An independent fashion retailer signs an alliance with an e‑commerce platform to reach a wider online audience.
Case Study Snapshot – “Baker’s Delight” (Family‑Owned Small Business)
A family‑run bakery started in 2015 with 3 staff members. Within five years it expanded to 20 employees, supplied 15 local cafés and generated $1.2 million in annual sales.
Responsive product development based on direct customer feedback (organic product‑development).
Use of a micro‑loan to purchase a new oven, increasing output by 40 % (financial incentive in action).
Participation in a local business support network that provided free marketing workshops (advisory service).
Family ownership provided strong brand loyalty but required a formal succession plan to retain the founder’s expertise.
Considered a friendly takeover of a neighbouring patisserie to gain additional retail space – still under evaluation.
Summary Points
Small businesses form the backbone of most economies, driving employment, innovation, and balanced regional development.
They contribute a disproportionate share of GDP relative to their numbers, especially when micro‑ and small firms are aggregated.
Advantages such as agility and niche focus are offset by weaknesses like limited finance and vulnerability to economic shocks.
Family‑owned firms enjoy strong community ties but must manage succession and professionalisation challenges.
Growth is usually organic; external growth (M&A, joint ventures, alliances, franchising) offers rapid expansion but entails higher risk and complexity.
Successful external growth depends on strategic fit, cultural compatibility, realistic synergy estimates, and careful post‑transaction integration.
Targeted policy measures—financial support, regulatory simplification, advisory services, and dedicated infrastructure—can magnify the positive impact of small businesses.
