Just worth noteing this looks specific to the US freelance/contract market.

I can only speak for the jurisdiction I know (and I am not a lawyer, just a former freelancer), but in the UK this contract would not be suitable for someone wishing to operate outside of IR35 (disguised employment rules) as it makes no mention of substitution, direction or control, which are the key factors when determining IR35 status.

Not necessarily a failing of the project, but perhaps it could mention more explicitly that it's for US jurisdiction

(For UK freelancers I recommend looking at IPSE membership which includes access to their contract templates which are good and commonly accepted as standard contracts)
