How do I reset quickbooks. Messed a few things up and now need to reset it all

Good to see you here in the Community, @info172.

Let me walk you through the steps on resetting QuickBooks Online account to start fresh with your books.

If you're using QuickBooks Online Plus or Essentials version and the account was signup within 90 days, you have an option to purge the data to reset your account. 

This process will delete all the data in your company file, and you can no longer restore it. 

To purge the data, you can follow the steps below:

1. Log in to your QuickBooks Online account.
2. Change the URL to include /purgecompany. Example: URL shows https://qbo.intuit.com/c28/app/homepage, change to: https://qbo.intuit.com/c28/app/purgecompany.
3. The next screen will provide a summary of the items to be deleted.
4. Type the word “YES” once the data gets deleted, then click OK.
5. Click Wipe Data once your selections are complete.
6. Once the deletion is complete, you will be rerouted to your home page.

However, if your account is more than 90 days old, you can't delete the data. Instead, you have to cancel your account and start a new subscription. 

To do this, you can follow the detailed steps in this article: Delete your data and start over in QuickBooks Online. 

Please know that I'm just a post away if you have additional questions about resetting QuickBooks data. Have a good one!
