I need to reset my QuickBook account from when my subscription started. How can this be done

If you are using QBO Simple Start or your account > 60 days old, you should open a new blank account instead.

Hello Tbfleicester-gma, 

Welcome to the Community page, 

Is your account within 90 days or is it older? If the ac count is within the 90 days then you could just purge your account and start again if it is older then the 90 days then it wold be just a case of taking out a new account with us and starting again and cancelling the old account you dont want anymore.
