Steps in the Procurement Cycle:
An employee identifies a need and submits a Purchase Requisition.
The Requisition goes through automatic budget check and then into an automated internal approval process.
Once approved, the purchasing department converts the Requisition into a Purchase Order.
The Purchase Order is sent to the supplier electronically.
The supplier accepts the Purchase Order, creating a binding contract.
Goods or services are delivered according to the terms.
The invoice from the supplier is received electronically, approved by appropriate employee, and promptly paid by the Accounts Payable Department (typically by ACH, otherwise by check or credit card).
