Sole proprietors represent one of the major factors in Croatia's economy development and the performance of proprietorship activities in the Republic of Croatia is regulated by the Sole Proprietorship Act. Unlike starting a company, the legal requirements for starting a sole proprietorship are somewhat simple, which makes this one of the entrepreneurs' key motivators to dive into the world of entrepreneurship by opening a sole proprietorship. Although they are small entrepreneurs, proprietors are the bearers of a large part of the national economy due to their production of goods and services, as well as providing employment opportunities for other persons in the labor market. Given the lower level of bureaucratization in business, they are far more adaptable and ready to respond quickly when faced with the numerous challenges of the modern market. The credibility of this statement is reflected in the current COVID-19 crisis during which the cease of business has caused major market disruptions, such as the inability to get products shipped from distant suppliers as well as the termination of working positions in large scale systems, which has led entrepreneurs towards adapting their businesses in order to provide the necessary goods and services in their local market. The business adjustment consisted of changing product ranges and distribution services, which they have imaginatively and skillfully adapted to the newly developed situation. Given the aforementioned, it is clear that sole proprietors are an important factor in the national economy and as such should be met with approval. Therefore, I believe it is necessary to reduce pressure of national regulations and make it easier for them to do business.
