This is a snippet of a larger article that originally appeard in a 2016 issue of Entrepreneur.

The franchising business is booming, and nowhere is that more evident than Entrepreneur’s fastest-growing franchises ranking. Growth is the goal of every franchise system, of course, but not all achieve it as successfully as our top performers.

A total of 105 companies were ranked, represent inga total of 9,695 new franchises opened in North America between July 2014 and July 2015, an almost 32 percent increase from the previous year’s growth. The companies are ranked based on their growth during that time frame, with ties listed alphabetically.

As you look over this listing and take in some words of wisdom from the fastest-growing companies, keep in mind that the ranking is not intended as an endorsement of any particular company. Growth is just one sign of a healthy franchise system, but finding the right opportunity for you requires due diligence. Before investing, always read the company’s legal documents, consult with an attorney and an accountant, and look beyond the numbers by talking to franchisees about their experiences.

Here are the top 20 fastest-growing franchises of the year (click here for the complete list):
