The process begins when the purchasing manager
checks the inventory subsidiary ledger on his computer terminal each morning. When inventory is
deemed to be too low, he reviews the valid vendor
file, also from his terminal, to select vendors for
items to be purchased. Once a vendor is found, he
prepares an electronic version of the purchase order,
in addition to two hard copies of the purchase order.
One hard copy is sent to the vendor immediately,
while the other is filed in the department. Immediately
after this event, the electronic version of the purchase
order is sent out to two terminals: one in the receiving
department and one in the accounts payable
department
