Hi there, greg-concretearm..
The QuickBooks Self-Employed is designed for small business. That said, the option to manage inventories is unavailable.
You'll need either QuickBooks Online Plus or Advanced to track and manage inventory lists. Here's an article for more information: Set up and track your inventory in QuickBooks Online.
Otherwise, you can look for an inventory management app to supervise your inventories separately.
I'm just a post-away if my assistance is in need about inventories. Have a good one!
