It's nice to see you here in QuickBooks Community, info-alsooqwhole. Yes, there's a way to upgrade plan if you're on Apple billing. Let me share how QuickBooks subscription works and ensure you'll be routed to the right support so you can upgrade smoothly.
Managing a QuickBooks subscription depends on where you bought your subscription. Since your subscription is from Apple, I suggest contacting their support team. They have the tools to pull up your account and deeply investigate why you don't see an option to upgrade your plan or the reason why your QBO subscription still shows on their end. They can also assist with the procedure of how you successfully change your subscription so you can start using an Inventory feature.
On the other hand, in case you want to transfer your QuickBooks Online (QBO) billing from Apple to Intuit, you can open this article on how to process works: Transfer your billing to QuickBooks to sign up for QuickBooks Online Payroll.
Lastly, refer to this article if you need help on how to manage your inventory items in QBO: Set up and track your inventory in QuickBooks Online.
Feel at ease to get back to this thread if you have other questions about handling your billing and subscriptions in QBO. I'm always here to help, info-alsooqwhole. Have a nice day!
