anyone have any advice on how to invoice internationally from the US as a sole proprietor? Been living in the States for a while now, but I still have some Euro clients left and I need to send a bill.
Here I've just billed my freelance work with the W9/1099 system. Would that or something similar work when billing from California to the Euro-zone? I'm not really looking to set up my own business or getting an accountant, as working under my own name is not my main focus right now.
