Based on my experience that has pioneered the business with a husband who is a former manager and supervisor of a bank. Business can fail because :

A businessman is not persistent, persistence is a must in business, you do not immediately expect big profits if you laze around.

Not mastering the ins and outs of the business well, running a business can not try. you must equip yourself with sufficient knowledge about the business you are running.

Can not control employees, based on our experience, it is very difficult to find employees who are loyal and responsible for their work, therefore it takes good managerial knowledge to control employees to work in accordance with what you expect.

Lack of promotion, not smart to use media campaign can be cause your business closed.

Do not be an entrepreneur who only commands employees, but show that you also want to intervene, so you will be role models by employees. my husband's experience as a bank manager has alerted us to not hesitate to show a direct example of how to do work on the employees.

A business can close because there is no calculation of profit and loss. a financial record is indispensable to know with certainty the expenses and expenditures earned from the business.
