I cannot downgrade clients from Plus to Essentials. Support even tried and said it is because I am on the new billing system. Any suggestions?

Hi madgelmiller,

Are you also the Master Admin your client's account? If you, you can downgrade the subscription by following these steps:

1. Click on the Gear icon.
2. Select Account and Settings.
3. In the Billing & Subscription, click on the downgrade link.
4. Select the version and click on save.

Please revisit the pros and cons in this article prior to downgrading: Downgrade Your QuickBooks Online Subscription.

Hi EdSanderson,

QuickBooks Online allows the Accountant, Master and Company Admin to downgrade the account. Let's make sure you're using either one of these login credentials. 

When the downgrade button is still unavailable, you can click on the Cancel button and reactivate the account. Then, the downgrade option will be available. Please note that you might need to reenter the billing information.
