So, this thread, like many others has been open for over a year and a half - asking for what has to be a very simple feature that almost every other provider has seemed to figure out. 

In fact, but not having this, Qucikbooks itself is losing out on more money themselves since the cant skim more off with their processing fee after the tip. 

Are we ever going to see a tip option? I like many others are tired of waiting and will be jumping ship.
