on the phone with support -- says this was an issue several months ago, but no issues seen currently.

Went through all of the trouble-shooting steps everyone suggested. (Thank you all, but none of them worked).

Only thing i can think of (which I suggested to support) was that this account was created a decade ago when we were using the desktop version -- we switched over to QBO maybe 5-6 years ago?

I have a similar problem with some Income accounts as well -- accounts created on desktop which cannot be made Inactive in QBO. No services, items, etc. are linked to these accounts, but they cannot be made Inactive. I've not had Support specifically look at these accounts re: this issue.

Wondering whether that is the underlying problem? Support says desktop-created vs. QBO-created is not the issue. But...what other underlying difference is there?
