Final answer:
Starting a business from scratch is tougher due to higher financial risk, the need to build a brand and create operational systems, and the personal liability involved for sole proprietors, whereas buying a franchise provides a proven model and brand recognition.
Step-by-step explanation:
Starting a business from the ground up is more difficult than buying an existing business or a franchise because it often involves greater financial risk, the challenge of establishing a brand, and the necessity to develop operational systems from scratch. When you buy a franchise, you are purchasing the rights to use a business model that has already been tested and proven, with access to training, supply chain support, and support in setting up operations. This comes with the benefit of the franchisor's established brand recognition and customer base. On the other hand, starting a business from zero means needing to raise capital, which could involve dipping into personal savings or seeking out angel investors or venture capitalists. Furthermore, as a sole proprietor, you face the burden of personal liability which could lead to losing personal assets in the event of bankruptcy or a lawsuit.
