The 10 Most Profitable Small Businesses
Despite the seeming dominance of large corporations, small businesses continue to be the engine of the North American economy. According to the U.S. Small Business Administration (SBA), approximately 550,000 new small businesses are established every month in the U.S., creating two out of every three new jobs. Over half of Americans own or are employed by a small business.
While it is common knowledge that most successful small businesses start with a great business idea backed by a solid business plan, some businesses/industries have higher profit potential than others. If you are an entrepreneur or investor looking for a new small business opportunity, limiting your choices to the most profitable small businesses listed in this article is one of the best ways to ensure success.
In addition to profitability potential, many of the businesses listed below are experiencing strong demand due to the continuing trend by corporations to outsource business functions such as accounting, payroll, information technology, social media, legal services, and even marketing. Many former full-time employees of larger businesses have become self-employed due to outsourcing, and the trend shows no signs of slowing down.
