Auditors test controls and important transactions within the accounts payable process when conducting the audit of the Acquisition and Payment Cycle. Particular focus is placed on the application of various control actions to manage spending. Segregation of duties, a crucial control procedure used by Gilead Sciences, Inc., makes sure that tasks related to accounts payable are clearly divided into categories and coordinated with the proper journal entries. This separation ensures a distinct separation of duties, improving the precision and integrity of financial transactions.
