A Small and Medium-sized Enterprise (SME) refers to a business that maintains revenues, assets, or a number of employees below a certain threshold. These thresholds can vary by country and industry, but SMEs are generally recognized for their significant role in driving economic growth, innovation, and job creation. SMEs often face unique challenges, such as limited access to financing and resources compared to larger corporations. However, they also benefit from flexibility and the ability to adapt quickly to market changes. Governments and organizations often provide support programs to help SMEs thrive in competitive environments.
