QB Issue Resolution:

If both are on different locations then the options for you are the ff:

You can subscribe to QuickBooks Online to access the company file any time, anywhere.

Second, would be hosting wherein you will be able to have full access of your QB anytime anywhere with your laptop or tablet through internet connection.

Third, would be recommended applications that will work with your QB and your system. I would like to set your expectation though, that applications would be for third party providers.
