Has anyone been unable to successfully downgrade their plan? I have tried over 50 times and had endless support chats with Quickbooks Online with no resolution/response.

I see the importance of achieving your goal in QuickBooks Online, @mckownk.

To help you clear things out. One of the reasons why you can't downgrade your account is if there's a feature in your account you enable that can't be turned off. An example is the Multicurrency feature.

In the meantime, I recommend contacting support again. They have the specific tools to pull up your account and help you look for the root cause of your issue.

Here's how to contact support:

1. Sign in to your QuickBooks Online, then click the Help (?) icon.
2. Select the Search icon
3. Select Contact Us.
4. Enter your concern in the box below What can help you with?, then click Continue.
5. Select How would you like to connect with us? either Have us all you or Chat with us.

If you need additional assistance with managing your subscriptions, never hesitate to reply to this post. Keep safe and have a blessed week! 

I have chatted with support on this already, multiple times. They cannot find the feature that needs to be turned off and neither can I. We have troubleshooted this and I was promised a response to my case but never got one. Ticket #[case number removed] is one of the tickets that was never responded to. 

I have contacted support about this and they cannot figure it out. We have troubleshooted over and over. Ticket [Removed]

I appreciate the troubleshooting steps you've tried to resolve the issue, @mckownk. Let me share some information about the feature available in the different subscriptions of QuickBooks Online (QBO). 

When downgrading your subscription, there are some features that are not applicable. If you currently have the multicurrency feature enabled with QuickBooks Online Essentials or Plus, you won’t be able to switch to QuickBooks Simple Start. In addition, downgrading will remove all discounts you have on your current plan.

 On the other hand, can you please tell me what subscriptions you are currently connected to? You can check it here: 

1. Go to the Gear icon.
2. Select Accounts and Settings.
3. Click Billing & Subscription on the left of the screen. 

You may need to cancel your account if in case you are using QuickBooks Essentials and subscribe to the downgraded version. 

Then, to give you further information about the support levels for each QBO version, check out this link: Pricing and subscription levels for QuickBooks Online. From here, you'll know the different features available for each version.

Additional details about this topic can be found in this article: Downgrade your QuickBooks Online plan. It lists all possible stoppers for a downgrade attempt. 

I'd love to know updates on how this goes. Please don't hesitate if you have any further inquiries about QBO features. I'm always here to answer your queries to achieve your goal. Have a great day, and take care.
