Our company is in this predicament as well and it seemed to be random with no evidentiary support of malfeasance, fraud or any other reason to hold the funds over 30 days. We too have over 10K in holding and are ready to sue for conversion. We have sent all the documentation requested by Quickbooks through it's payment solutions center and they are not releasing the funds. We're giving them 24 hours to get it sorted. Would love to know if anyone else is still waiting after having followed all the "requested steps" of document support and explanation of transactions?
