Am I able to start fresh in QBO. I am new to it but over 90 days. I can't figure out how to rectify the errors I made in the 1st month of my business on QBO. Unsubscribe?

The program allows you to delete the data on your account only if your account is under 60 days of usage since the date you started your subscription. If your account is within 60 days, please follow the steps below to delete your data:
 

Important note: This process will delete all the data in the company file. Once you delete it, you can’t restore it. This process is only available to QuickBooks Online Plus, Essentials, and EasyStart. 

1. Log in to your QuickBooks Online Company.
2. Change the URL to include /purgecompany
   Example: Change https://sg.qbo.intuit.com/app/homepage to https://sg.qbo.intuit.com/app/purgecompany
3. The next screen will provide a summary of the items to delete. Type YES to delete the data, then select OK.
