Purchase Requisition

A purchase requisition is an internal request to obtain approval for goods or services before a buyer commits the organisation to a supplier. It describes what is needed, why, quantity, estimated price, delivery need and budget or cost centre.

An approved requisition may lead to a purchase order, but the two documents serve different audiences: the requisition is an internal control and the order is generally sent to a supplier.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

A workshop manager notices a critical bearing is running low and requests fifty replacements, with a part number, preferred delivery date, expected supplier and estimated total. An approver checks need, budget and authority, purchasing may then obtain quotes and issue an order, and when supplies arrive receiving records the quantities while accounts payable compares the invoice with the order and receipt under the organisation's matching policy.

A digital requisition makes the trail easier to follow, and Oracle's iProcurement documentation describes carts converted to requisitions, supplier or internal sourcing and price and currency fields. Those are features of a vendor system, not a required template for every firm, and a small company can use a simpler controlled form if it clearly captures authorisation and links the request to subsequent records.

Approvals should reflect risk: routine low-cost stock can use a preapproved catalogue or bounded threshold, while an unusual large service contract may need budget-owner and legal review. Splitting a request into small pieces to avoid an approval limit undermines the control.

Set rules by total commitment including expected delivery and recurring charges, not only one line item, and make the approver independent enough to challenge the request and informed enough to do so. A good requisition states the business purpose without inventing urgency, and if an emergency purchase is necessary, an exception path can preserve a record and retrospective review while allowing needed action.

Endless serial sign-offs may cause staff to bypass the system, so track cycle time from request to approval and ask whether delays come from unclear specifications, missing budget, unavailable approvers or the sourcing step, then fix the bottleneck rather than remove every safeguard. Supplier communication needs a clear boundary, since a requester may discuss specifications or availability but should not imply that an internal approval constitutes an external order unless authorised.

An approved request can still be rejected by a supplier or revised after quotes, and purchase orders need their own accepted terms, quantities and delivery dates. For recurring services, the requisition should identify the expected term and maximum commitment so spending is not understated.

Accounting treatment happens later and depends on what was obtained: the requisition can reserve or plan budget, but it does not automatically create an expense or fixed asset. A purchase order may represent a commitment without recognised delivery, while invoice and receipt evidence support the subsequent posting.

Record cancellations and changes so outstanding requests do not inflate the procurement pipeline, and match currency and units consistently. For owners, choose a process proportionate to the organisation, give people clear approval limits, and tie requisitions to orders, receipts and invoices.

Report duplicate requests, exceptions and delayed approvals. The goal is timely purchasing with an auditable reason, not paperwork for its own sake.

In practice

Real-world examples.

1

Example

A marketing manager requests approval for a print job before issuing an order. The request states the quantity, the estimated cost and the campaign budget code. The budget owner approves it, and purchasing then obtains two quotes.

2

Example

A workshop attaches specifications and a budget code to a spare-parts request. The approver can see at once what is needed and which cost centre will pay. The request is approved on the same day.

3

Example

Finance at a logistics company flags several small requisitions that together exceed one approval threshold. The requests were raised by the same team for the same supplier within a week. The approver asks for them to be combined and reviewed as one commitment.

Formula

Calculation

No universal financial formula applies: a requisition is a control record. An illustrative request total can be estimated as Quantity x Expected unit price + Expected mandatory charges. Worked example. A fictional team requests 100 units at $45 each and expects $200 delivery. - Estimated request total = 100 x $45 + $200 = $4,500 + $200 = $4,700 before any applicable tax or later quote changes. - The amount helps route approval but is not evidence of a final invoice or expense. - If the approval threshold is $10,000 and the same team submits three similar requests of $4,700 on one day, the combined commitment is 3 x $4,700 = $14,100, which exceeds the threshold. Finance would ask whether the requests should have been one. Use actual quote and purchase terms before commitment.

Case study

Seen in the real world.

This illustrative and entirely fictional example follows Oasis Hospitality, an invented hotel group. Staff ordered cleaning products directly from multiple suppliers, and duplicate boxes arrived while budget owners had no visibility. The firm introduced a simple requisition with item, site, quantity, purpose, estimated cost and named approver. Purchasing consolidated overlapping requests, kept an urgent path for safety needs and linked approved requests to purchase orders. It measured time to approval and found one inactive approval queue, which it fixed.

Finance still reviewed invoices against receipts rather than treating requisition approval as proof of purchase. The invented case shows that a good control can prevent waste without stopping necessary work. In the invented numbers, the group had been buying about $6,000 a month of cleaning products across five hotels and discovered that around $900 a month was duplicated stock. After consolidating requests, the duplicated amount fell to near zero, and the group negotiated one supplier price for the combined volume.

Watch out

Common mistakes.

  • Treating an approved internal request as an accepted supplier order.
  • Splitting purchases to evade a higher approval level.
  • Creating approvals so slow that staff routinely bypass them.

Questions

People also ask.

Is a requisition a purchase order?

No. It is an internal request; the purchase order is usually the external purchasing document.

Does it record an expense immediately?

No. Later receipt and accounting facts determine recognition.

What should it contain?

At minimum a clear need, quantity, estimate, budget and approver appropriate to the risk.
