An entrepreneur is someone who starts a business and takes on the financial risk, organizing and managing the business to sell products or services for a profit. Successful entrepreneurs are hard working, creative, honest, persistent, caring, confident, and knowledgeable. Buyers are individuals or organizations that agree to purchase finished goods or services, or raw materials for production. Sellers are individuals or groups that transfer ownership of goods or services to buyers in exchange for money, acting as vendors, creditors, dealers, or suppliers. The duties of sellers include conducting business fairly, delivering orders on time and to the correct location, and providing warranties for products.
