If you are unsure if all of your bank accounts are reconciled up to date or not, you can check this by going into Bank & Cash > List Reconciled Statements.
If you are closing the period to 31/08/2019 and you have reconciled up to the 26/08/2019, you must enter a blank reconciliation against your bank(s), shown below:
Note: Your closing balance should read the same as your opening balance as nothing will be selected when reconciling. You do not need to amend the page numbers, these will roll over into your next “true” statement.
Once your dates and closing balance have been entered, you can go ahead and reconcile the blank statement. You must repeat this process for any other bank accounts not yet reconciled up to or after the date you’re closing down for.
