If your QuickBooks Online data is less than 60 days, you have the option to purge your account if you're using QuickBooks Online Plus, Essentials and Advanced. The system deletes all data entered into the company, and you're unable to restore or reverse them.
To purge the data, follow the steps listed below:
Log in to your QuickBooks Online account.
Change the URL to include /purgecompany.
Example: URL shows https://...qbo.intuit.com/app/homepage, change to: https://...qbo.intuit.com/app/purgecompany.
The next screen will provide a summary of the items to be deleted.
Type the word “YES” once the data gets deleted, then click OK.
Click Wipe Data once your selections are complete.
Once the deletion is complete, you will be rerouted to your home page.
If your it's 60 days old or older, you need to cancel your account and start a new subscription.
To cancel your account:
Go to Gear icon and select Account and Settings under Your Company.
Select the Billing and subscription tab.
In the QuickBooks section, select Cancel.
Follow the steps to cancel your account. If you use payroll, you should cancel your payroll account too.
