I understand the inconvenience of having to go through such a process, @Morgan1509.

At this time, we don't have an option to inactivate multiple accounts when using QuickBooks Online. This would be a great feature especially if you have multiple accounts that you'll need to make inactive.

I'll be sure to pass this along to our developers. This way, they can check and consider this in future product updates. 

In the meantime, I recommend visiting our QuickBooks Online Blog to know more about our latest happenings. From there, you'll get the recent news, features, and updates about QBO and what our Product Team is working on.

Please post again in the Community if you need anything. I want to help in any way I can. Have a good one.
