Hey Pat - sorry for the delay in getting back to you.
We looked into it, and you are correct, the inventory adjustments did not update the Quanity On Hand in method. Similarily, making an inventory adjustment in QuickBooks directly would not update the Quantity On Hand in Method. Furthermore, sales orders, invoices, bills, etc, did not update the Quantity On Hand, Quantity On Order or Quantity On Sales Order. So that was bad news for inventory people like yourself. That's why we have beta ;)
Good news is that all the above is all changed now. No need to create a new account, or publish new screens, it will start happening automatically. A little inside scoop - you'll actually first see the Quanity On Hand set to empty initially, and wait for QuickBooks to update it with an updated quantity. This ensures that you are getting accurate numbers, but the downside is that if QB is not connected to Method you won't see updated quantities until it connects again.
Sample date in QuickBooks - don't think there is a way to change that. Best thing to do is create your own sample file, or just create and rename a backup of your real QB file and use that instead. Just make sure you know which file you are using when you are using QuickBooks so you don't by mistake type in real data into a dummy file!!
