Light entrepreneurship is an easy and hassle-free way to work on a job in an entrepreneurial way without having to commit to accounting services and financial management costs. As a private trader, you usually commit to monthly fees for financial management of various services. Starting as a light entrepreneur is free, while starting a business as a private trader costs money. The main difference between being a light entrepreneur and being a private trader is that as a light entrepreneur you do not have a Business ID and can start and stop your usage of the invoicing service immediately.
