One advantage of sole proprietorship is that decisions are made promptly. This is because the sole proprietor has full control over the business and can make decisions without needing to consult with other owners or shareholders. This allows for quick decision-making, which is essential in a fast-paced business environment. Additionally, the sole proprietor can make decisions that are aligned with their personal values and goals, without needing to consider the interests of other owners or shareholders. This can lead to a greater sense of autonomy and flexibility in running the business. However, it's important to note that this advantage comes with the potential downside of having no one to bounce ideas off of or share the workload with.
