Great, short article chock-full of recommendations, well-organized (Intuit Resources, Third-Party Resources & User Groups/Social Media), and written by one of my favorite colleagues, Stacy Kildal (who also runs a great program for training professional QB folks).

The only two resources I’d make sure to add on top of the ones she mentions are QuickBooks Power Hour (run by Hector Garcia & Michelle Long), as well as Hector’s own free video series, on QB Desktop, QB Online, and especially the Advanced Topics courses.  I believe his entire collection is organized here, though subscribing to his YouTube channel gets you updated videos as they’re released.
