It's crazy how slow it is to get anything done with Quickbooks Online. The site is slow to respond, it has very limited keyboard shortcuts, if you open it in multiple tabs to cross reference information, it's constantly logging you out of the other tab, and they discontinued the desktop electron wrapper that let you have more than one tab open.
Historically, a huge strength of Intuit was the huge population of bookkeepers and accountants who would recommend QuickBooks to clients, but I don't see how anyone would recommend it at this point.
