For example: You provide a marketing service for a company/small business. Lets say it's digital marketing. You use pirate software for the bulk of your work. And maybe you take a tad bit too much pay. What you do is not illegal, but maybe there would be issues with complaints, tax, refund, ect. How would you go about handling the payments? Would you start an official business or just keep it simple with paypal/other? Considering you only do services the freelancing way. The reason i ask is because I'm planning on doing this myself. But as an uber-noob, I have no clue on how to deal with the administrative side of things. *edit: The issue here is that you want to look professional, and not raise red flags and so on. But at the same time you don't want the full responsibility of a "real" business. Hope you get what i mean.
