Purchasing is the operational activity of buying approved goods or services. It typically covers purchase-order creation, supplier confirmation, delivery or service receipt, invoice checking and payment coordination. Procurement is broader: it may also include demand planning, sourcing strategy, supplier selection, negotiation and performance management.
Where purchasing begins and ends
Purchasing should start after a business need and buying authority are clear. It ends only when the transaction record is complete enough for the organization to confirm what was ordered, received, invoiced and paid.
- Receive an approved request. Confirm the specification, budget, quantity and required date.
- Create the purchase order. State the supplier, line items, price, currency, delivery and payment terms.
- Obtain supplier confirmation. Resolve changes before delivery rather than after the invoice arrives.
- Record receipt. Capture accepted goods, services, shortages or damage.
- Check the invoice. Compare the invoice with the order and receipt, then investigate exceptions.
- Authorize payment. Pass approved details and supporting records to accounts payable.
- Close the order. Preserve the transaction history and any supplier-performance issue.
| Area | Purchasing | Procurement |
|---|---|---|
| Primary focus | Executing approved supplier transactions | Managing how the organization obtains external goods and services |
| Typical activities | Orders, confirmations, receipts, invoice checks and payment handoff | Planning, sourcing, evaluation, negotiation, contracting and supplier management |
| Time horizon | Current operational requirement | Current and future category or supplier needs |
| Core record | Purchase order and matching documents | Sourcing decision, contract and supplier-performance record |
The record must survive a partial delivery
When a supplier confirms only part of an order, purchasing records the revised commitment, alerts the receiving team and leaves the balance open. Accounts payable can then match the invoice to what arrived. Speed gained by skipping receipt evidence is borrowed from invoice reconciliation.
Controls that keep work moving
- Use approved suppliers and verified bank details
- Separate request, approval and payment authority where practical
- Give every order a traceable owner and status
- Record changes instead of silently editing the original commitment
- Match invoices against the order and evidence of receipt
- Escalate price, quantity, tax or bank-detail discrepancies before payment
