For $39/mo I get QB 2012 Premier, automated off-site backup, QB Connect (web-based access to your QB data. Basically it's web-based QB) and QB Mobile. Frankly, the mobile app is weak but i can view client data, create invoices and estimates. No way to capture expenses, though. I also use Act! and some sync program that allows it to share data w/QB. All in all, this whole setup works fairly well.
But now I'm eying this new service called Service Autopilot. Anyone ever hear of it?
