Purchase Procedure Steps
Following are the steps of the purchase procedure in the ERP purchasing system.

Purchase Requisition
Before sending the requisition, it is necessary to identify the goods or services to be purchased, and it is also vital to select the right supplier.
Once all these are done, purchase requisitions will be submitted. Purchase requisition contains full details of goods or services to be purchased.
Requests for Quotation
A request for quotation goes out before any order is placed. It is sent to several candidate suppliers with the specification, quantity and required delivery date, and asks each to quote a price and a lead time.
The responses are what let you choose the supplier and agree the price, so the RFQ has to precede the purchase order. Issuing a PO first and requesting quotations afterwards would mean you had already committed to a price you had not yet tested. For repeat items covered by an existing contract or blanket agreement this step is skipped, which is much of the point of holding those agreements.
Review and Approval
With a supplier and a price selected, the requisition goes for approval. The accounting department verifies that funds are available and the request is authorised at whatever level the value requires.
Approval belongs here, before the order is raised, because a purchase order is a commitment to the supplier. Approving after the PO has already gone out turns the control into a formality.
Purchase Order
The approved requisition becomes a purchase order and is issued to the selected supplier. The PO carries the item detail, quantity, agreed price, delivery schedule, and the terms and taxes that apply, and once the supplier accepts it, it is a contract.

Review of Receiving Goods/Services
Once goods or services delivered by the vendor are received, they will be reviewed carefully to ensure that received goods/services are ordered only.
Matching of Documents
This is the three-way match, and the three documents are the purchase order (what was agreed), the goods receipt (what actually arrived) and the supplier invoice (what is being charged for). Only if all three agree on item, quantity and price does the invoice pass for payment.
It is the main control against paying for goods that were never delivered, or paying a price nobody agreed to. Systems normally allow a tolerance so a trivial difference does not block a payment, and route anything outside it to a buyer to resolve.
Invoice Approval and Payment
Once the goods and the documents are verified, the invoice is approved and the buyer pays the supplier according to the terms recorded on the purchase order. Any of the three documents disagreeing puts the invoice on hold instead, which is the whole purpose of matching them.
