The full-time or part-time of an entrepreneurial activity depends on the scope of your business. The decisive factor in assessing full-time or part-time activity is the amount of work, not the income you receive.
The business activity of a full-time entrepreneur is so large that it is not possible to receive a full-time job. If the business is again small and there are no plans to expand, then the entrepreneur is generally considered to be a part-time entrepreneur.
Full-time and part-time entrepreneurship is related to unemployment security when the amount of unemployment benefit is assessed.
