Hi Mike, A special time entry with a negative rate could reverse such charges...but if added to the "real" person, would double-count the hours, so although you could use a "pretend" person for such cases, if the Hours matter, I suspect you'll need to either delete or (more transparently) move them to some other Project (e.g. "Hour Corrections") to stay whole, and use a financial transaction (e.g. a fixed amount credit "off" the next invoice) to reverse the charge.
