How do I delete one of my companies?

Hi, @JYcebu.

You'll only need to cancel your subscription to make your account inactive or deleted. This looks like you're closing your account. For the complete steps, follow these steps:

1. Sign in to QBO account as an administrator. 
2. Go to the Gear icon and select Accounts and Settings.
3. Select the Billing & Subscription tab.
4. In the QuickBooks section, select Cancel or Cancel Trial.

Still, you'll have read-only access to your account a year after the cancellation. If there's important information entered in QBO, it would be best to export or print them before canceling your account. 

Please let me know how it goes by leaving a comment below. It's my priority to ensure you're able to delete your account.
