Trying to upgrade subscription

Hi there, malandscapeandfencing.

We'd want to make sure you're able to manage your subscription successfully. If you haven't already, please use a different browser and log back in to QBO. You can use Mozilla, Google Chrome, Microsoft Edge, and Safari if you're using a Mac computer.

Then, go back to the Billing and Subscription section and click the Upgrade link one more time. 

If you're getting the same prompt, please contact our phone support. They can verify your account details and process the upgrade for you. Here's how: 

1. Click the Help menu in the upper-right hand corner of QBO.
2. From the Search tab, enter Contact Us.
3. Select the Contact Us button.
4. Choose Callback.

To know our support availability hours, please check this article: Get help with QuickBooks products and services.

Let me know if you need anything else.
