Small tech companies, such as software development and IT consulting, make a lot of money. They offer valuable services to customers around the world, generating a lot of revenue. Law firms provide legal services to individuals, businesses, and other organizations. Many law firms specialize in a specific segment of law. As a small business, profits average 20.5%, making it a large profit margin if you have a law degree and a professional license.
