Hi Ben,
The tables you see in your old account are from the discontinued Method Warehouse app. Over the summer, we removed these tables from any new accounts, which is why you don't see them in your new trial. These weren't tables that connected to QuickBooks, so there's no lost functionality.
All of the standard inventory fields in QB is available (QTYonHand, QTYonOrder, QTYonSalesOrder). Our beta sync engine also has the ability to sync to Advanced Inventory in QB. This is only available through the beta sync engine. If you wish to work with this new feature, just send me an email and I can send you the beta version of the sync engine.
