Let me welcome you first to the Community, Marion3.
I can provide some information about migrating your desktop inventory to the online version.
When importing the desktop file, indicate if you want to import inventory into QuickBooks Online. Since you don’t want to migrate the inventory, mark the radio button for No, don’t bring over inventory or track quantity on hand.
Once you select this option, set up new items later in QBO. For more insights about the conversion process, the following guides provide an overview of the tasks to perform to ensure your legacy file is in a clean slate.
If you have any clarifications or other concerns, leave a comment below. I’m more than happy to answer them for you. Enjoy the rest of the day.
