Small spool but precious. This proverb is true in relation to private business, which allows you to get decent profits with a minimum of costs. In most developed countries, small and medium-sized businesses form the basis of the economy. And it is not surprising, because at the minimum cost a private entrepreneur can get far from small profits. But, of course, success largely depends on the sphere in which you want (and can) work – services, production, transportation, trade, etc. So who makes the most money? Forbes magazine tried to answer this question, making a list of the most profitable and promising segments of small business. The rating is based on data on 300 thousand firms and individual entrepreneurs, each sphere was represented by at least 100 companies. Data was collected by a specialized consulting agency from 2003 to 2011. As the authors of the rating note, most of the most profitable types of entrepreneurship require excellent professional training. At the same time, these specialties allow you to work for yourself, not to support the staff, and sometimes not even use the office. But there is another side to the coin: clients of such specialists, as a rule, have resorted to the services of the same professional for many years, that is, it is very difficult for a beginner to quickly take a decent position in the market. So, who got into the business top? 1. Private auditors. Net profit – 16.5%. Audit services are in demand at all times, so the financial crisis did not affect the income of these specialists. In addition, clients, as a rule, regularly work with the same auditor (or company), so the cost of promotion is practically unnecessary. Well, of course, if you work for yourself, the need for renting an office and paying staff completely disappears. 2. Chiropractors, 15, 3%. Official medicine does not always recognize the craft of these specialists, but this does not prevent them from earning a decent income. And those who do not have their own office and work on leaving the client’s home have almost no costs. 3. Specialized clinics, 15%. The most popular are small operations, cosmetic procedures and various examinations. Despite the high cost of maintaining such an institution, prices for services more than cover all costs.
