Small and Midsize Enterprises (SMEs)
What is an SME?
Small and midsize enterprises (SMEs) are businesses that fall between microenterprises and large corporations based on thresholds such as number of employees, revenue, or total assets. Exact definitions vary by country and sometimes by industry.
Common roles and characteristics
- Outnumber large firms and account for a large share of employment and economic activity.
- Tend to be entrepreneurial and more flexible than large firms.
- Often operate in industries with lower upfront capital needs (e.g., legal practices, dental offices, restaurants, local retailers).
- Require fewer and simpler enterprise systems and organizational processes than multinational corporations.
- Strong local and community ties; frequently family-owned or closely held.
How countries define SMEs
Definitions differ widely:

- United States
- The Small Business Administration (SBA) sets size standards by industry (for example, many manufacturing firms qualify as small if they have 500 or fewer employees, though some industries allow higher limits).
- The Internal Revenue Service (IRS) distinguishes small businesses for tax reporting by asset thresholds (e.g., $10 million).
-
The U.S. has tens of millions of small firms; most have no paid employees. Roughly 6.4 million are employer firms.
-
Canada
- Micro: 1–4 employees
- Small: 5–99 employees
- Medium: 100–499 employees
- Large: 500+ employees
-
Businesses with fewer than 100 employees make up the vast majority of employer firms.
-
European Union
- Micro: up to 10 employees
- Small: fewer than 50 employees
- Medium: fewer than 250 employees
-
SMEs account for about 99% of all businesses and contribute a large share of employment and GDP.

China
- Size classification is complex and varies by sector (based on revenue, employees, or assets). Example thresholds include retail firms with 10–49 employees and certain revenue bands for real estate and agriculture.
-
National plans prioritize cultivating and supporting millions of SMEs, with special emphasis on innovation.
-
Developing countries
- Often use the acronym MSME (micro, small, and medium enterprises).
- SMEs are a dominant source of employment and income in many emerging economies; estimates suggest they generate the majority of formal jobs, but face substantial financing gaps.
Economic importance
- SMEs typically represent the vast majority of firms in national economies and employ large portions of the workforce.
- In many countries SMEs contribute significantly to GDP (for example, they account for more than 40% of U.S. GDP in some estimates).
- They drive innovation, provide niche and local services, and circulate revenue within communities.
Advantages of SMEs
- Greater operational flexibility and faster decision-making.
- Stronger local integration and community support.
- Higher likelihood of locally reinvesting earnings and sustaining local supply chains.
- Focused product or service offerings that deeply serve specific target markets.
- Preservation of family and community business traditions.
Challenges faced by SMEs
- Limited access to capital and credit relative to larger firms.
- Higher sensitivity to regulatory and tax burdens.
- Resource constraints for scaling, technology adoption, and export activity.
- Financing gaps are especially acute in developing countries, where unmet needs run into the trillions of dollars.
Support and incentives
Governments and development institutions commonly offer programs to help SMEs survive and grow:
- Financial support
- Loan programs with guarantees or capped rates (examples include SBA-style 7(a) loans).
- Long-term, fixed-rate financing for asset purchases (comparable to 504 loans).
- Microloans for startup and expansion financing (often up to tens of thousands of dollars).
-
Investment through licensed small business investment companies (SBICs) that combine public support with private capital.
-
Non-financial support
- Training, mentoring, and business development coaching.
- Regulatory relief, tax incentives, and programs to improve market access.
- Export assistance and innovation grants.
Typical eligibility for investment programs (example requirements)
* Business must meet national small-business size standards.
* A majority of operations, assets, or employees may need to be domestic (e.g., at least 51% in the country).
* Some industries (real estate, financial activities, farmland) are commonly excluded from certain public financing programs.

Examples
- A single-location, independent coffee roaster or local legal practice is a typical SME.
- Large chains that began as small businesses (e.g., early-stage companies that later expanded globally) eventually cease to be SMEs as they grow beyond national size thresholds.
Conclusion
SMEs are foundational to most economies: they generate jobs, foster innovation, and sustain local communities. Because definitions and thresholds vary, policy responses and support programs are typically tailored to national and sectoral circumstances. Strengthening SME access to finance, skills, and markets remains central to boosting economic resilience and inclusive growth.
