The answer depends on how you entered your trial balance in the beginning of your fiscal year. Did you use a converter from Sage to QuickBooks. The scheme is to enter last year's trial balance. Create an item and point it Retained Earnings. Enter the open invoices using that item. Second, enter outstanding bills using the same item. Third, enter all banking transactions that have not cleared using the same item. Check your end-of-year trial balance to the QuickBooks balance for the same period.
