                                16–17 VERIFY THAT ALL RECEIPTS ARE ENTERED                   343
                                       IN THE COMPUTER AT ONCE
                                There is nothing that throws a wrench into a company’s production planning
                                and accounting more than the delayed entry of warehouse receiving into the
                                computer system. When this happens (or rather, when it does not happen), the
                                purchasing staff does not know if materials have arrived and they begin a series
                                of frantic calls to suppliers to determine when items are to be shipped. Like-
                                wise, the production scheduling staff decide not to produce something because
                                they do not see any receipt in the computer system. Finally, the accounting staff
                                has a very difficult time determining what was really received at the end of the
                                accounting period, resulting in the reporting of inaccurate inventory figures in
                                the financial statements. All this because someone in the warehouse is slow in
                                entering receipts.
                                   The obvious best practice is to make the warehouse staff make their receiving
                                entries as soon as they receive any parts, but the solution is not quite so simple.
                                The underlying reason why receipts are not being entered at once is probably
                                because the staff is too busy to do it, and so this chore waits until a slow period,
                                perhaps at the end of the day. Thus, to make them enter receipts more quickly, one
                                must find a better way to enter the receipts, one that is so simple and easy there is
                                no excuse to delay the process. One way is to require all suppliers to attach a bar-
                                coded sheet to all shipments, allowing the receiving staff to scan this sheet directly
                                into the computer system, thereby recording the entry. This is a quick and easy
                                way to approach the receiving data-entry task. Another is to restructure the receiv-
                                ing data-entry screen so that one only needs to enter the purchase order number
                                upon which any receipt is based. The purchase order then comes up on the screen,
                                and the receiver quickly notes the quantity received. This latter approach is also a
                                good way to pay customers without the extra effort of using the accounts payable
                                staff (see Chapter 3). The latter approach carries with it the added benefit of forc-
                                ing suppliers to provide only the purchase order number with their shipments—
                                many suppliers resist having to bar code the information on their shipments. Either
                                technique is an effective way to reduce the time needed to enter receipts, thereby
                                eliminating a host of downstream problems.

                                ON THE INVENTORY FUNCTION


                                The impact of the best practices described in this chapter on the inventory func-
                                tion is a considerable increase in the accuracy of inventory information. They
                                are not designed to directly improve the functions of the warehouse, since this
                                book only deals with accounting improvements. Nonetheless, it would be surprising
