Yes, at times I prefer to only take on one client at a time. Some have asked for proof that only a certain percentage of my income is coming from their project. In some instances I was able to satisfy their inquiry, in others not. I understand the need to protect against employers trying to dodge employment taxes and benefits, but it's frustrating that it's making simple contract arrangements harder to navigate, even when both parties prefer 1099 to FTE.
