If Categories are enabled in QuickBooks Online, then all parents of a multi-level product mapping MUST be a product Category and the lowest level MUST be a Product.
Product Categories
The “Product ID” field on the Procurement > Products list in ConnectWise PSA will map to the “Category” and “Name” fields (separated with a colon “:”) on the Company > Lists > All List > Products and Services screen in QuickBooks Online. If a Product in ConnectWise PSA does not exist in QuickBooks Online, it will be created automatically by Gozynta Mobius. Please note, however, that the Product Category will not be created and must already exist in QuickBooks Online.
