Businesses fail because owners are not in touch with their customers, don't offer something unique, don't communicate well, are bad leaders and have bad business models. These problems eventually lead to a lack of cash flow that force businesses to close.
Business owners must listen to and learn from their customers succeed, and they must have an approach that differentiates them from other entrepreneurs. They must also communicate their message well by being clear, concise and compelling. Business owners who are lacking leadership skills must learn them for their ventures to succeed. Businesses must quickly correct weak business models that aren't built using proven tools and technologies for a business to succeed.
