The managers forward the invoice and purchase order to the accounting department for payment. Which of the following internal controls would efficiently prevent abuse of this system?
- Institute a company policy requiring rotation of orders among several suppliers.
- Require a manual receiving report from the warehouse prior to payment.
- Forbid the use of emergency purchase orders.
- Review the level of safety stock.
