No messing around with distractions from your favorite web sites and it runs fast for sure since it’s not bloated with features irrelevant to QuickBooks Online. This is actually a specialized browser tuned just for QBO – a thin client that installs on your PC or Mac just like any other program, and when started it goes directly to your QBO instance. Regular browsers can be used for viewing QBO screens however Intuit recommends using the QuickBooks Online QBO Desktop App (QuickBooksInstall.exe) just Google it to get this download from the QB app store. It’s great to see all of this at once, without switching back and forth. I always use at least 3 monitors at once, allowing simultaneous viewing of, say, a QBO reconciliation screen, the check register, and a pdf of the bank statement all at the same time. This feature can be leveraged much further by using multiple monitors. Multi-windows are a given in QB desktop products (and in fact too many can open after a while) but this is a new feature in QBO.

Viewing two or more screens at the same time increases productivity dramatically in QuickBooks Online, and diminishes stress from constantly switching back and forth between transactions and reports. View QuickBooks Online in Multiple Windows
