A couple of things. I need an app that's fully integrated with the full version of my quickbooks desktop. Or I need to find a compatible traveling device to take with me onto my jobs that my quickbooks desktop can be downloaded onto.
How about a remote desktop application? For a nominal fee an app like Splashtop (my go to) let's you use almost any internet connected device to access your stationary computer back at tge office as if you were there. Laptop, tablet, even phone. You can get the free version of Splashtop to try it out on your local network or WiFi
