error occurs when trying to cancel my subscription

Let's work together to help you cancel your QuickBooks Online (QBO) account, Damo.

Could you please specify the exact error message you encountered? This helps us better isolate the issue. Then, if you’re logged in as a standard user, you won’t be able to cancel your subscription. Let’s ensure you log in as the administrator or the primary user to go through the process.

Sometimes, your browser's cache or cookies can get in the way of canceling your account. Try clearing your cache to remove any stored files and browsing history. If that doesn't help, you can also try using a different supported browser or device.

Once done, cancel your QBO subscription again. For additional steps on unsubscribing from your account, depending on where you bought your subscription, check out this article: Cancel your QuickBooks Online subscription or trial.
