QuickBooks Online

App has some quirks, but it's a really great thing the support is outstanding, quick, and knowledgeable to get you through them. Vincent is radically different (read: EFFECTIVE) from the typical Quickbooks Desktop + Online support I've had to deal with for decades, and saved my team literally hours of trying to figure out some duplicate customer/invoice sync issues. He not only solved the sync issues, but singlehandedly transformed my admittedly negative view of QB Support--enough for me to write a glowing review a 1:00 AM. Kudos to the OneSaas team, and hat's off to Vincent.
