It has been our pleasure being part of your business, byday76. Let me get the help you need to ensure you'd able to cancel your account.
You can cancel your subscription directly through the settings of your QuickBooks Online (QBO) account.
Here's how:
Click the Gear icon at the upper-right hand.
Choose Account and Settings.
In the left menu, pick Billing & Subscription.
Hit Cancel subscription, then Continue.
Complete the short survey.
Once your QBO account is cancelled, your data will be available in read-only access for 1 year and be deleted in the system from the cancellation date.
