I guess I did misunderstand where the QuickBooks database was going to reside.
If you are going to have the QuickBooks database on the server, you’ll need to have the QuickBooks listener running on the computer that will have QuickBooks open. This way, it can listen to the changes being made in QuickBooks and update it using Method PUSH to your Method database.
Typically you would have the listener running on each computer that opens QuickBooks and it is automatically opened each time QuickBooks is launched. In your case, since it is a copied database that you are using for your own testing, the listener would only need to be installed on one computer.
Hopefully that makes sense.
