Seidman Incorporated is a manufacturer of aluminum cans for the beverage industry. Seidman purchases aluminum and other raw materials from several vendors. The purchasing process at Seidman occurs as follows: When inventory of raw materials seems low, the purchasing department prepares a three-copy purchase order. The first copy is mailed to the vendor, the second copy is filed by PO number in the purchasing department, and the third copy is sent to the accounts payable department. The purchasing department also prepares and sends a blind purchase order to the receiving department with only item numbers (no item description) and quantity ordered. When ordered items arrive at the receiving dock, the receiving department compares the quantity received to the quantities listed on the blind purchase order and fills in the item description. The receiving department sends the completed blind purchase order back to the purchasing department, where it is filed with the purchase order. The receiving department then updates inventory records. Vendors mail invoices directly to the accounts payable department. The accounts payable department matches the items on the invoice to items on the purchase order. If matched, the accounts payable department updates the accounts payable subledger and files them by invoice pay date. At the end of each month, the accounts payable department receives monthly statements from vendors. It reviews the statement carefully for calculation errors and files them by vendor and month. If an error is identified, the accounts payable department contacts the vendor to resolve the error and requests a new statement. At the end of the month, the general ledger department updates inventory and accounts payable general ledger accounts. Describe six weaknesses in Seidman Incorporateds process or internal controls.
