Yes, you have the option to start all over with QuickBooks Online, cel5146.

Before starting from scratch, you'll want to export your data first since you're unable to restore the action once you delete your account.

If your account has been active for more than 60 days and you need to start from scratch, you cancel your account and start a new subscription. 

To cancel your account:

1. Go to the Gear icon at the upper-right, then select Account and Settings.
2. Select Billing & Subscription on the left.
3. Click Cancel to the right of the Subscription status line.
4. Follow the on-screen prompts and it’ll walk you through the rest of the process.

Then, start an account by signing up through this link: https://quickbooks.intuit.com/global/. However, if your account has been active for less than 60 days you can delete the data. Here's how:

1. Log in to your QBO company.
2. Change the URL to include /purgecompany.
   Example: URL shows https://qbo.intuit.com/c28/app/homepage, change it to https://qbo.intuit.com/c28/app/purgecompany.
3. The next screen will provide a summary of the items to be deleted. Type the word “YES” once the data gets deleted, then select OK.
4. Select Wipe Data once your selections are complete.
