Small and medium-sized enterprises (SMEs) are businesses that maintain a limited scale of operations. They are typically defined by their number of employees and annual revenue, which varies by country. SMEs play a crucial role in the economy, contributing to job creation and innovation. These enterprises often face unique challenges, such as limited access to funding and resources compared to larger corporations. However, SMEs are known for their flexibility and ability to adapt quickly to market changes, making them vital players in local and global economies.
