Thank you for reaching back out to us, @GlenYoung007.

I can share some insights about the 3rd applications compatible with QuickBooks.

Intuit strives to treat all businesses fairly and we know that each one has different needs. The App Center though has all kinds of third-party applications to choose from. You can look them over to get a better comparison of these apps and see if one meets your needs.

You can check out this link: Apps for QuickBooks Desktop.

Meanwhile, I want you to know that I value your time and the success of your business. I'll personally prepare a feedback statement to send to our product engineers about the ability to change/edit the account associated with your inventory items. 

It's feedback like this that empowers us to make QuickBooks the best software it can be.

Let me know if you have other questions in mind. I want to ensure your success in everything you do. Wishing you all the best!
