Description of the Inventory System
Customer Orders for manufactured products
Orders from customers are received at the Sales Order Department by telephone or fax. The
Sales Order Department raises a multi-copy sales order, two of which (the invoice copies)
are priced and totalled. The order is entered via a computer terminal located in an open
access area within the department.
Inventory – raw materials into goods store
. University of Southern Queensland
12 ACC3118 – Auditing
The inventory is controlled by the Storeroom Manager (Jim Shine) and two storeroom clerks.
All are well trained in the custody and control of chemicals.
The Factory Manager (Joe Kenton) prepares a Purchase Requisition in respect of the raw
materials required which specifies 3 items of information about the materials required: the
chemical description; the quantity required; and the supplier from whom the purchase should
be made. The Factory Manager then sends the requisition to the Purchasing Department
where a formal Purchase Order is raised and sent to the supplier. Where a supplier is unable
to supply a particular order, the Factory Manager recommends a new supplier.
Raw materials are kept in a large purpose built locked compound which includes
underground storage tanks. When deliveries are made to the storage tanks the item is pumped
from the tanker directly into the underground storage tanks. The delivery driver hands a
Delivery Docket to a storeroom clerk as proof that the goods were delivered to the
When ordered raw materials arrive from suppliers, one of the storeroom clerks counts the
item and formally signs the delivery docket as evidence of receipt of the chemicals. He then
telephones Accounts Department advising the payments clerk that the goods from a supplier
has been received. He follows this up a later date with an email. All signed delivery dockets
are filed in the Store Manager’s office. The stock quantity is entered into the inventory
system via a computer terminal located in the Storeroom Manager’s office. The goods are
physically stored in either the goods store or the compound.
Inventory – raw materials from goods store to production
Raw materials are removed from the compound or goods store only upon written or oral
authorisation by the Production Manager.
Inventory – finished goods from production to goods store
As finished goods leave the production area, they are sorted into product type and entered
onto “Finished Goods from Production” tickets. The tickets are then given to a storeroom
clerk who enters the data into the inventory system via the computer terminal located in the
Storeroom Manager’s office. At the end of each day, all tickets are batched and a control
total is created on units. On an ad hoc basis, this control total is agreed to the daily printout
of finished goods entered into the store.
