I use QB Pro Desktop with payroll on a computer at the store. I will be gone for 6 weeks and will have a computer with QB Pro Desktop with payroll. I will be only processing payroll and invoicing customers on the traveling computer. When I return, I want to merge the files from the traveling computer to the store computer so the store computer will be up to date with the traveling computer. How do I set them up before I leave and when I return. The traveling computer does not have any QB files installed but it does have The QB software installed.
Currently, there's no option to merge the two company files from the traveling computer to the store computer. You can only use one file for 2 separate computers. To do this, I'd suggest moving your company file from the store computer to the traveling computer. Please note that performing the steps won't affect your product license.
Consider deploying a private cloud on your premise. You will access you company file by internet connection. It would be easier to manage it then migrate data between files as long as your connection is reliable during your trips.
