Product Item Types
It is important to note that there are 4 different Item Types in Manage with configurable “Type Xref” values when defining a Product Type: Inventory Part, Non-Inventory Part, Other Charge, and Service. These XRef values dictate which item type will be created in QuickBooks Online. The “Type Xref” can be set in Manage System > Setup Tables > Product Type. These four different types map up in QBO to Stock, Non-stock, and Service. Both Other Charge and Service in Manage match to Service in QBO.
