If you completed the new bank information in the EasyStep Interview, you might have already entered your statement ending balance. Click Banking > Use Register and select your bank account to open the register. If you have a balance in the register, check to see that it agrees with your bank balance as of the start date in QuickBooks. If the amount has a memo of Opening Balance, you can be sure it was probably created during the EasyStep Interview process. If the amount is correct and agrees with your bank’s statement ending balance, you are fine. If not, double-click the transaction and edit the
amount. Otherwise, use the steps listed in Chapter 1 of the QuickBooks 2010 Solutions Guide for entering your opening bank balance.
