Monitoring Accounts Payables

In creating shareholder value, one objective of management is to increase the speed of cash inflows and reduce the speed of cash outflows. To accomplish this task, management must understand the relationships that cause accounts receivable and accounts payable to change. The paper expands a receivable monitoring model by Gentry and De La Garza to incorporate the causes of changes in payables. Several examples are developed to show the operation of the model. The three primary contributions of the paper are (a) developing algorithms that measure the causes of changes in payables, plus an interpretation for each set of conditions; (b) showing that a present value approach to monitoring payables is superior to a recommended accounting approach based on variance analysis; (c) finally, presenting an approach for ranking the performance of payable and receivable strategies.
