Even in computerized accounting systems, there can be many manual tasks. This is usually true for small or midsize companies with small-scale IT systems. The examples shown in the early parts of this chapter of screen captures from Microsoft Dynamics® accounting software depict such a system. In purchasing systems, the document matching is often called a three-way match. A three way match is the matching of a purchase order to the related receiving report and invoice. The person operating the computer software must still physically match the purchase order to a receiving report and invoice, deciding which invoices match which purchase orders and receiving reports. The computer automates much of the record keeping and check writing, but a human must still make decisions regarding this matching process, depicted in Exhibit 9-19.
Within small or midsize organizations with accounting software such as Microsoft Dynamics®, the following tasks must be completed by employees:
This manual entry and matching system is extremely time consuming and expensive. It is time consuming due to the complexities of purchases. Purchasing and payments can become complex because a vendor may occasionally substitute items, ship a different quantity (undership or overship), notify the buyer of back orders, or fill a partial order. Thus, matching takes a large amount of human time to reconcile and approve for payment. This is true even if the accounting system is maintaining records and generating checks electronically. The problems with this system are as follows:
Many organizations are using advances in IT systems to reduce the time and expense of purchase and payment processing. With technology, processes can be changed to lessen or eliminate the aforementioned problems. The process undertaken to change processes to enhance efficiency is called business process reengineering. Recall from Chapter 1 that business process reengineering (BPR) is an organized change in business processes for the purpose of improving efficiency and effectiveness. BPR aligns business processes with the IT systems in order to accomplish these improvements. In the case of purchasing and paying for purchases, BPR facilitates reductions in paperwork, manual processing, and processing costs. In many cases, IT systems are used to enhance the efficiency of purchasing and payment processes. Implementing these IT systems usually entails BPR to make the processes fit the IT system.
Examples of IT systems that usually involve BPR in purchasing and payments include the following:
For example, EDI reduces or eliminates the manual keying of invoices because the invoice is communicated electronically between the buyer and the vendor. The next section describes these IT systems that allow organizations to reduce the time and cost of processing purchases and payments.
