made the following notes about the inventory system:

Procedures for raw materials

Separate systems, staff and warehouses are maintained for both raw materials and finished goods

Purchase orders are automatically generated by the computer when stocks of any raw material fall

below 70% of the prior month’s usage The purchase orders contain the following details:

· date;

· supplier name and address;

· raw material needed

Three copies of the purchase order are produced and distributed as follows:

· copy 1—to warehouse to enable follow up of late orders

· copy 2—filed by accounts clerk in date order

· copy 3—sent to supplier

When raw material stocks are received, the bar codes attached to the delivery boxes by the supplier are

scanned into the system A two-part Goods Received Note (GRN) is then produced:

· copy 1—matched to warehouse copy of purchase order by stores staff

· copy 2—filed by accounts clerk

The scanning process is aborted if the codes do not match those on the masterfile

Procedures for finished goods

Production orders are automatically generated when finished goods fall below 60% of the prior

month’s sales The production orders contain the following details:

· date;

· sub-contractor’s name;

· raw materials required;

· finished goods needed

Two copies of the production order are produced:

· copy 1 – to raw materials store for use as a picking slip, then it is packed with goods and sent to the

supplier

· copy 2 – filed by production controller in date order

When the finished goods stocks are received, the bar codes attached to the delivery boxes by the

supplier are scanned into the system A two-part GRN is then produced:
