To delete your data in QuickBooks Online (QBO), we can either purge your company or cancel your subscription, depending on how long you've been using QBO.
If your books are below 60 days old, we can start fresh with a new QBO company by purging your data. Please note that this is only available in QBO Essentials, Plus, and Advanced.
However, if your books are beyond 60 days, we can cancel your subscription. When canceling, we delete your data after one year, and it will be available in read-only access.
If you still wish to contact our customer support to delete your company, please follow the steps below:
Go to Help and select the Search tab.

Choose between Chat with us or Have us call you.
QBO Plus, Essentials, and Simple Start support hours are available Monday to Friday from 6 AM to 6 PM PT and Saturday from 6 AM to 3 PM PT. QBO Advanced supports, on the other hand, are available daily at any time of the day.
