Hi Louise, thanks for joining the QB Community - as the banking function wasn't set up until recently, we'd recommend checking that an opening balance has been entered and that the status of this has been set to reconciled within the Chart of Accounts. The OB is the balance of the account on the date that transactions began to be tracked in QuickBooks; if there were no transactions in the account at this time, then there won't be an entry for this. You can check for any existing OB by navigating to the Chart of Accounts > Account history (beside the bank account) > Click the DATE heading to reorder from oldest > newest. If no OB has been recorded, you can enter & reconcile this using a journal entry by following the steps listed here.
