Key Functions and DutiesSegregation of Duties Possible Errors or Fraud

The purchasing function should be segregated from the requisitioning and receiving functions.

If one individual is responsible for the requisition, purchasing, and receiving functions, fictitious purchases can be made. This can result in the theft of goods and possibly payment for unauthorized purchases.

The invoice-processing function should be segregated from the accounts payable function.

If one individual is responsible for the invoice-processing and accounts payable function, purchase transactions can be processed at the wrong price or terms, or a cash disbursement can be processed for goods not received. This can result in overpayment of goods or the theft of cash.

The disbursement function should be segregated from the accounts payable function.

If one individual is responsible for the disbursement function and also has access to the accounts payable records, unauthorized checks supported by fictitious documents can be issued, and unauthorized transactions can be recorded. This can result in theft of the entity's cash.

The accounts payable function should be segregated from the general ledger function.

If one individual isresponsible for the accounts payable records and also for the general ledger, that individual can conceal any defalcation that would normally be detected by reconciling subsidiary records with the general ledger control account.
