The Types of Small Businesses That Make the Most Profit

If you’re looking to start a profitable business idea, it might be time to brush up on your number crunching skills.

Over the past 12 months, accounting services topped the list of the 15 largest sectors in the small business sector by net profit margin, according to financial information firm Sageworks. The list was compiled from a database of more than 1,000 financial reports from private companies with annual revenues of less than $10 million.

According to Sageworks data, accounting tops the list for generating the highest profit margins, but the rest of the list is dominated by service-oriented companies in healthcare and real estate.

Sageworks analyst Jenna Weaver points out that many of these service sectors consistently rank high on lists of “most profitable” sectors. “Service-based industries often have very healthy bottom lines,” she says. “Their overhead and equipment costs are often relatively low, and much of the time, it doesn’t take a lot of upfront investment to get started.”

Weaver adds: “Often times, in cases like consulting, accounting, and legal services, you can get started right inside of your house, without even worrying about renting a space.”
