Final answer:
Copies of a Purchase Order (PO) are usually sent to Inventory Control, Receiving, and Accounts Payable, but not to the General Ledger.
Step-by-step explanation:
Copies of a Purchase Order (PO) are typically sent to various departments within a company to facilitate the procurement process and ensure records and inventory are properly managed. The departments that usually receive a PO copy include Inventory Control, to adjust stock levels; Receiving, to acknowledge the arrival of goods; and Accounts Payable, to process payment to the supplier. However, a copy of the PO is not normally sent to the General Ledger as this department deals with the summary-level data of all accounts, rather than the transactional documents like POs.
