What does the company do well? Simple yet powerful business accounting software on the Mac. With additional payroll module, it's a powerhouse.
What does the company not do well? Removed ability to do online invoicing/payments a few years ago and has yet to add it back. Also, QB for Mac 2019 doesn't behave like other Mac apps with regards to respecting the Dock boundary - despite repeated talks with their support team. This should've been fixed years ago - but really only an issue on 13-inch MBPs.
What do you wish you had known about the company before using? Been using it so long I can't even remember.
