Avantages
Intuit still has integrity in their offerings, in their culture, and in their DNA. Its great to be able to trust that the people who are doing so much with financial data are actually above reproach and not involved in any kind of shady industry practices. Mistakes happen, but in the time I've been here (10+ years) they really are missteps and mistakes and not intent to deceive or defraud anyone.
Inconvénients
Intuit is in the middle of a pivot. They keep selling off and shrinking down. They are down to pretty much two market areas, neither of which is growing. (Quickbooks and TurbotTax) Of course they will tell you there is a lot of growth in Quickbooks online, but its from Quickbooks desktop. Actual "new to the Product" growth is very low. Intuit has managed to successfully pivot 2 or 3 other times. They still are in the middle of this one, so time will tell, but for now, I wouldn't put money on a successful change.
