Hi there, jearn,
QuickBooks Online lets you remove companies you no longer use. To do so, you'd need to cancel those companies. They'll disappear from the list after 365 days.
There are just a few steps to get this done. Here's how:
- Sign in to QuickBooks Online as an admin user.
- Go to Settings ⚙, then select Account and Settings.
- Select Billing & Subscription.
- On the QuickBooks section, click Cancel subscription.
- Follow the steps on the screen to cancel your subscription.
Once done, an email will be sent confirming that we've canceled your subscription.
I've added a quick video tutorial for your guidance with the process above.
You can also refer to this article: Cancel your QuickBooks Online subscription for more details.
Let me know if there's anything else you need. I'm always glad to help you out.
