Procurement terms,
explained plainly

Thirty terms that come up constantly in procurement and finance, written the way somebody would explain them to a new starter rather than the way a standards body would define them.

Useful for onboarding. Also for the moment a stakeholder asks what committed spend actually means.

Why this page exists

Most procurement arguments are really vocabulary problems

Two people can discuss committed spend for twenty minutes before discovering they mean different things by it.

Finance often means money that has been invoiced but not paid. Procurement usually means money promised on an approved order that has not been invoiced at all. Both are reasonable readings and they produce very different numbers.

The same happens with sole source and single source, with requisition and order, and with anything involving the word spend. None of it is complicated, but it is rarely written down anywhere a new starter can find it.

So this is that page. Thirty terms grouped by where you meet them, each explained in a sentence or two, with a note on why the distinction matters where it genuinely does.

Buying and catalogs

The words you meet raising a purchase

Ten terms covering everything from the first request to the order going out.

Purchase requisition

An internal request asking for permission to buy something. It names what is needed, which department needs it, which budget it draws on and when it is wanted. It commits nothing to a supplier and can be changed or refused freely.

Purchase order

The commitment sent to a supplier once a request has been approved, listing items, quantities, agreed prices and terms. Unlike a requisition it is contractually meaningful, which is why changes to it are versioned rather than overwritten.

Blanket purchase order

A single order covering repeat purchases from one supplier across a period, with individual releases drawn against a master value. Useful for predictable spend where raising a fresh order each time adds nothing.

Catalog

A list of products and services at pre agreed prices that requesters choose from instead of describing what they want in free text. The single most effective way to keep buying inside negotiated rates.

Punchout

A catalog arrangement where a requester is taken to a supplier's own site to shop, with negotiated pricing applied, and returns with the basket attached to their request.

Preferred supplier

A supplier your organisation has negotiated with and approved. The list only produces savings if it is enforced at the moment of purchase rather than published in a policy document.

Maverick spend

Buying that happens outside the agreed process. Almost always a symptom of the compliant path being slower than the alternative rather than deliberate rule breaking.

Off contract spend

Purchases from a supplier you hold an agreement with, but at prices outside that agreement. Easy to miss because the supplier name looks correct on the report.

Spend under management

The share of company spend flowing through approved procurement processes. Most other savings depend on this number rising first.

Tail spend

The long tail of low value, high volume purchases spread across many suppliers. Typically a small share of spend across most of the transactions, and where catalogs help most.

Sourcing and competition

What people mean by running an event

Six terms that come up whenever a purchase is large enough to be worth competing.

RFQ

A request for quotation. You have written the specification and want suppliers to price it, so price is the main variable and comparison is straightforward.

RFP

A request for proposal. Used where you need suppliers to propose an approach rather than only a price, and responses are evaluated against criteria.

Reverse auction

A sourcing event where pre qualified suppliers bid downward in real time. Suppliers usually see their rank rather than each other's prices, which keeps competition genuine without a race to the bottom.

Baseline

What you currently pay, calculated from actual historical transactions rather than memory. Savings claimed against a guessed baseline rarely survive their second quarter.

Award

The decision to give the business to a supplier at the end of an event. Worth recording with its reasoning, because the question of why that supplier was chosen always arrives eventually.

Single source

A category with only one capable supplier. Not the same as sole source, which is choosing one supplier when others exist and usually needs justification.

Budgets and payment

Where procurement meets finance

Ten terms, and the group where the same word most often means two different things to two people.

Charge code

The budget line a purchase is charged against, usually mirroring the account structure finance already reports on. Every request carries one, which is what connects a purchase to a budget.

Committed spend

Money promised to a supplier on an approved purchase order that has not been invoiced yet. Reporting that counts only invoices leaves this out, which is why budgets that look healthy sometimes are not.

Available balance

What is genuinely left on a budget after both spent and committed are deducted. The only figure that answers whether somebody can buy the thing they need.

Encumbrance

The accounting term for recording a commitment against a budget at the point of approval rather than at invoice. Common in public sector finance and increasingly expected elsewhere.

Reallocation

Moving available budget from one charge code to another. Worth treating as a recorded action with an approver rather than an edit, so the trail explains itself later.

Accrual

Recognising an expense for goods or services received but not yet invoiced. Calculating these from open commitments and goods receipts removes most of the manual work at month end.

Three way match

Comparing the purchase order, the goods receipt and the supplier invoice before releasing payment. The oldest control in accounts payable and still the most effective.

Straight through processing

An invoice that matches cleanly and posts without human review. The share of invoices achieving this is the headline measure of accounts payable automation.

Credit note

A document reducing what you owe a supplier, usually issued after a short delivery or a pricing correction. Should stay linked to the order it relates to so the net position stays accurate.

Payment terms

The agreed period before an invoice is due, such as net thirty. Terms run from a defined trigger, often invoice date or goods receipt, and the difference matters more than people expect.

Suppliers and control

Onboarding, receiving and who is allowed to do what

Six terms covering the supplier relationship and the controls around it.

Supplier onboarding

Collecting and verifying everything needed before a supplier can be paid, including tax forms, insurance, banking details and any certifications your industry requires.

Goods receipt note

The record of what physically arrived against a purchase order, covering quantities, condition and any variance. It is the third document in a three way match.

Vendor master

The authoritative list of suppliers and their details. Duplicates and stale records here cause payment errors and hide opportunities to consolidate spend.

Segregation of duties

Ensuring the person who requests, the person who approves and the person who pays are not the same. Best enforced by the system rather than by policy, including through delegation chains.

Approval matrix

The rules deciding who approves what, usually by amount, category or department. Most useful when procurement can change it directly rather than raising a request to have it changed.

Delegation

Temporarily passing approval authority to somebody else, normally during leave. Should be scoped and time boxed, with both names kept on the record.

Pairs people mix up

Five distinctions worth getting right

These are the ones that cause real confusion in meetings, usually without anybody noticing.

PairThe differenceWhy it matters
Requisition and orderA requisition is internal and commits nothing. An order goes to a supplier and is a real commitment.Approving a requisition is not the same as being on the hook for the money
Committed and spentCommitted is promised on an approved order. Spent has been invoiced and posted.A budget report showing only spent is weeks out of date at any moment
Sole source and single sourceSingle source means only one supplier can do it. Sole source means you chose one when others existed.The second usually needs a written justification, the first does not
RFQ and RFPAn RFQ prices a specification you wrote. An RFP asks suppliers to propose the approach as well.Sending an RFQ when you needed an RFP produces confident quotes for the wrong thing
Goods receipt and delivery noteThe delivery note comes from the supplier. The goods receipt is what you recorded after counting.Only one of them is evidence you can match an invoice against

FAQ

Definitions people search for most

What is the difference between a purchase requisition and a purchase order?
A requisition is the internal request asking for permission to buy. It commits nothing and can be amended or refused freely. A purchase order is issued to the supplier after approval and is a genuine commitment, which is why changes to it are versioned and larger changes go back for sign off.
What does committed spend mean?
Money promised to a supplier on an approved purchase order that has not been invoiced yet. It is the figure most budget reports leave out, and the reason a budget that appears healthy can turn out not to be.
What is a three way match?
Comparing the purchase order, the goods receipt and the supplier invoice before releasing payment. When all three agree within your tolerances the invoice can clear without review. When they disagree it is held with the evidence attached.
What is a charge code?
The budget line a purchase is charged against, usually mirroring the account codes finance already reports on. Every request carries one, which is what connects an individual purchase to a budget.
What is maverick spend?
Buying that happens outside the agreed process. It is worth treating as a symptom rather than a discipline problem, because it almost always means the compliant route was slower than the alternative.
What is the difference between sole source and single source?
Single source means only one supplier is genuinely capable of providing what you need. Sole source means you chose one supplier when others existed, which normally requires a written justification.
What is a goods receipt note?
The record of what physically arrived against a purchase order, including quantities, condition and any variance. It is the third document in a three way match and the control that prevents paying for goods that never turned up.
What is tail spend?
The long tail of low value, high volume purchases spread across many suppliers. It is usually a small share of total spend but most of the transaction count, which is why catalogs and automation help disproportionately here.
