In some classifications, a small business has fewer than 100 employees while a mid-sized business has 100-999 workers.
The term SMB typically refers to Small to Medium-sized businesses that have fewer than 1,000 employees. SMBs are more variable in size, ranging from 10 employees or less up to about 1000 employees.
