This is a different product in my eyes. Most of the "outsourcers" really take over the entire payroll function, which divorces it from your accounting records --- and then later they try to stuff the results back into accounting through a GJE entry.
If the circumstances are right (small company, few employees, low transaction volume), then QB is just what you need -- without being too much. If you've got WAY more complexity, then start looking around.
WARNING -- if you are familiar with "The Baseball Player Problem" which is known as a ROAMING EMPLOYEE, you'll have to look elsewhere. I'm told by Intuit that there are NO intuit products that can do multi-state income tax withholding (and I'm an Intuit certified Pro Advisor, so I've spoken to everyone who should know). If you don't know what that issue is, then don't worry about it --- plow forward.
