I want to redo the entire chart of accounts - is that possible?

Happy to have you here on the Community page, @clarkjohnsoncpa.

At this time, we're unable to redo the entire account from the Chart of Accounts. The good news is, you can make the accounts inactive or delete it and recreate new accounts.

To delete the accounts:

1. Select Chart of Accounts from the Lists menu.
2. Right-click on the account, then tap on Delete. 
3. Follow the steps for the rest of the accounts.

To create new accounts:

1. Go to the Lists menu, then Chart of Accounts.
2. Click on the drop-down arrow beside Account.
3. Tap on New to add a new account.
4. Choose a category under Categorize money your business earns or spends, then Continue.
5. Add the Account Name and fill in the rest of the details.
6. Save the account.
