European Union (EU) SME Definition. In the EU, a similar system is used to define Small to Medium Enterprises. A business with a headcount of fewer than 250 is classified as medium-sized; a business with a headcount of fewer than 50 is classified as small, and a business with a headcount of fewer than 10 is considered a micro-business.
