When starting a business in Turkey, especially for small and medium-sized businesses, it's best to start a sole proprietorship. If the business continues and grows significantly, it can be converted into a limited liability company. This is because, in the event that you want to close the company, closing and liquidating the financial liabilities is much easier for a sole proprietorship than for a limited liability company. The establishment and monthly expenses of a sole proprietorship are lower than those of a limited liability company.
