I'm here to help you record the items that were being purchased, MrTopazAl,
In QuickBooks Online (QBO), if you want to track the items as inventory, you can record them as inventory items. However, since you don't purchase them for the stock, you can record them as non-inventory. Please read this article on how to record them: Add Product And Services Items To QuickBooks Online.
As for the shipping fee, that is already included in the vendor payment. You'll want to create a service item for that fee. Creating a service item is the same as when you're adding an item as non-inventory. You'll only need to select Service.
I have included these help articles in case you have questions about QuickBooks Online.
