Focus on giving your customers more than they expect. Give free samples or occasional discounts or gifts of some sort. Write thank you notes or call your customers to show them that you care about them. When you treat people as if they are a valuable asset, they will tell other people about you. They will also reward you by coming back over and over again.
Entrepreneurs seem to enjoy worrying about money because they do it so often.
There is no doubt about it, cash flow is the number one concern for everyone in business. Very few business owners have as much money as they think they need. It is amazing how many business owners are vague about their money. They don't like to take the time to keep accurate records and then they wonder where all their money went or why they don't have enough. If you pay attention to your money and nurture it, it will multiply.
