Processing a purchase order is the sequence of steps that turns an approved need into delivered goods and a paid invoice, with controls at each stage. In most organisations it runs like this.

## The flow

1. **Requisition.** Someone raises a request with the item, quantity, need date and cost centre. The budget owner approves it.
2. **PO creation.** Procurement converts the requisition into a purchase order, taking the supplier and price from the contract or sourcing result.
3. **PO approval.** Routed by value and category to the authorised approvers.
4. **Dispatch and acknowledgement.** The PO is sent to the supplier, who confirms price, quantity and delivery date. Any change is agreed before shipment.
5. **Receipt.** Goods or services are received and checked; a goods receipt note is recorded against the PO lines. Shortages and damage are logged.
6. **Invoice.** The supplier invoices with the PO number on it.
7. **Three-way match.** Accounts payable compares invoice, PO and receipt. Matches within tolerance are approved automatically; exceptions go to the buyer.
8. **Payment** on the agreed terms, and the PO is closed.

## Where it goes wrong

POs raised after the goods arrive, prices typed by hand, receipts not recorded, and invoices without PO numbers. Each creates an exception that someone has to chase.

## Making it faster

Automate requisition-to-PO from catalogues and contracts, enforce no PO no pay for covered categories, and let the system handle the matching. The buyer's time then goes to exceptions and suppliers, not data entry.
