I would also be interested in joining any kind of class action against QB. We recently moved our processing over to them and within a couple days they closed our account, seized over $10k of our clients money which was in process and the only explanation they can give is that it was a "business decision". We have not received an answer as to whether we will receive our money back or not, but this has wiped out a large portion of our company's cash. As a small business this has been a devastating experience and they do not seem to be in any hurry to release our funds or pay interest on the cash they are witholding.
