You can't purge your QBO account if it is > 60 days old or you use QBO Simple Start. You will have to signup for a new account.

As an additional option, use a backup restore app to lower any future risks.

Yes, all of these are possible, @AKAK-SAGA.

I'd be glad to guide you on the steps of how to delete bank transactions and start all over again in QuickBooks Online (QBO). 

Kindly follow these steps on how to delete bank transactions in QBO:
 

1. On your QBO account, go to the Banking tab, then select the correct bank account.
2. Go to the For Review tab then mark the items you want to delete. Tip: You can directly tick the box next to the Date column to select all transactions.
3. Select Exclude.
   
   
    
4. Next, go to the Excluded section, then tick the box next to Date to select all excluded items.
5. Once ready, click on Delete.
   
   

For detailed information, kindly visit: Void or delete transactions in QuickBooks Online.

Once done, you can then re-import transactions in QBO.

Moreover, if you decide to start over in QBO, you can either purge or cancel your account depending on how old your account is.

If your account is 60 days or older, you may need to cancel your current QuickBooks Online company and start a new one. However, if it's less than 60 days old, you can just purge your account.

For detailed information, kindly visit: Delete your data and start over in QuickBooks Online.

Additionally, I'll also share this link where you can search for articles that can guide you in managing your QBO account: QuickBooks Online Help Articles.

Thank you for the information.  If I delete my account and start over, do I have to pay for a new account?  

Good morning, @AKAK-SAGA. 

I appreciate you coming back and asking additional questions about starting over.

If your account is 60 days or older, you'll need to cancel your account and then pay for a new one. If it's less than 60 days old, you can simply purge your account without paying. 

For more details, check out this guide: Delete your data and start over. 

I hope this helps answer your question. Feel free to come back if you have any trouble along the way. Have a splendid day! 

How do we do “start over” for an accountant profile? I had a profile from a few years ago. I want to start fresh. How do I do this with a ProAdvisor account?

@ParrysBookkeeping 

As I know we are not allowed to purge QBOA accounts. You should signup for a new one with another email address.
