However, after examining a sample of non routine sales records you find that this control is not closely adhered to and that sales representatives offered discounts or altered sales terms that were not properly recorded in Sarbox's records, As a result, in instances when the control is not followed the recorded sales prices tend to be too high and/or terms are not correctly reflected in the sales invoice and the customers complain.
