The above can happen with other payment methods also. Access the booking that
is showing the error. Reduce the costing on the transaction(s) to nil. Go to
payment entry and refund the amount by the method that it had been originally
shown as being paid by. A refund document will generate. Return to the costing
screen and enter the correct transaction figures. Go back to payment entry and
retake the money by the correct method. Once this is completed the banking should
balance and the end of day procedure can continue.
