But it is to be noted that some differences are automatically adjusted. For example - A cheque that has been sent for collection, but not yet collected, causes a difference between the balance as shown by the pass book and the balance as shown by the cash book, but no adjusting entry is required in the cash book for such a difference because, the bank will credit the firm’s account as soon as the cheque is collected.
