In my experience a lot of freelancers are using it (especially when they like to work in different countries). Personally I’m quite happy using it and it’s a way better experience in comparison with the chamber of commerce in the Netherlands when you start freelancing (had some bad experiences unfortunately when they sold my data to shady companies which will target you with fake invoices/bad deals/spamming). Another great feature is that you are in full control how to pay yourself (salary/board member fee/dividends) which can have serious tax advantages depending on your country’s tax system.
