Is it possible to create a quote for a prospect WITHOUT an associated Account?

Although most of my clients pay for their services through their organizations, I have a few who pay out of pocket for 1-to-1 coaching. They don't have an associated account as they are processing these payments as individuals (not affiliated with any organizations, especially those in between jobs). When I tried creating a quote, I got the error that there must be an account associated with them. Does anyone know how to overcome this issue?
