What is Purchase Requisition?
Definition
A Purchase Requisition is an internal document used by employees to request approval for purchasing goods or services on behalf of the organization. It serves as the starting point of the procurement cycle and ensures that all purchasing requests are reviewed and authorized before procurement teams engage suppliers.
The requisition includes details such as item descriptions, quantity, estimated cost, supplier preferences, and business justification. It typically flows through a structured Purchase Requisition Workflow that verifies budget availability, compliance with procurement policies, and managerial approval.
By formalizing purchase requests before procurement begins, organizations maintain financial control, transparency in spending decisions, and alignment with procurement governance policies.
Role in the Procurement Process
Purchase requisitions play a foundational role in the procurement lifecycle by initiating the purchasing process in a controlled and documented manner. Once approved, the requisition becomes the basis for generating a formal purchase order issued to suppliers.
The transition from requisition to purchase order ensures that procurement teams can manage supplier transactions through structured controls such as Purchase Order Approval and verification of Purchase Order Accuracy.
This structured process prevents unauthorized purchases and ensures procurement activities align with departmental budgets and operational needs.
Key Components of a Purchase Requisition
A well-prepared purchase requisition contains detailed information that allows procurement and finance teams to evaluate the request efficiently. The content of the requisition ensures purchasing decisions are transparent and traceable.
Item description: Clear specification of goods or services required.
Quantity and pricing: Estimated cost information for budgeting purposes.
Department requestor: Identification of the individual or team submitting the request.
Required delivery timeline: Expected delivery or service completion date.
Business justification: Explanation of how the purchase supports operational objectives.
These details help procurement teams evaluate supplier options and move forward with formal purchasing activities.
Approval and Governance Controls
Purchase requisitions are subject to approval policies designed to ensure spending decisions follow organizational governance rules. Approval thresholds often depend on the monetary value of the request.
Many organizations implement structured approval mechanisms such as Purchase Order Approval and internal financial controls that align requisition approvals with budget limits and procurement policies.
Once approved, procurement teams generate purchase orders and track supplier commitments through governance tools such as Purchase Order Control and formal confirmation through Purchase Order Acknowledgment.
These controls ensure purchasing transactions are properly documented and traceable throughout the procurement lifecycle.
Operational Metrics Related to Requisitions
Organizations monitor procurement efficiency through performance indicators that measure how quickly and accurately requisitions convert into purchase orders.
One common metric is Purchase Order Cycle Time, which measures the time required to convert a requisition into an approved purchase order ready for supplier fulfillment.
Shorter cycle times typically indicate efficient procurement coordination and faster response to operational needs. Longer cycle times may indicate opportunities to streamline approval steps or improve requisition documentation quality.
Procurement teams also monitor pricing outcomes through indicators such as Purchase Price Variance, which compares expected purchase prices with actual supplier pricing during procurement negotiations.
Example Scenario
A marketing department requires new software licenses for a campaign analytics tool. The department manager submits a requisition for 20 licenses with an estimated cost of $15,000 through the organization's Purchase Requisition Workflow.
The request moves through managerial approval and procurement review to verify that the purchase aligns with the department’s budget and procurement policies. Once approved, procurement generates a purchase order and sends it to the selected vendor.
The supplier confirms the transaction through Purchase Order Acknowledgment, allowing the finance team to track delivery and invoice verification before payment.
This structured requisition process ensures the purchase is properly authorized, documented, and aligned with financial governance standards.
Requisition Adjustments and Change Management
In some situations, procurement requirements may change after a requisition is submitted. Organizations maintain control over such adjustments through structured amendment procedures.
Changes to procurement details may require formal updates through Purchase Order Amendment procedures once the purchase order has been issued. If the request is no longer required, the procurement team may initiate Purchase Order Cancellation to prevent unnecessary supplier commitments.
These change management mechanisms maintain transparency and ensure procurement records remain accurate throughout the purchasing lifecycle.
Summary
A Purchase Requisition is an internal request document used to initiate the procurement of goods or services. It begins the purchasing process by documenting operational needs and routing them through a controlled Purchase Requisition Workflow for approval.
Once approved, the requisition becomes the basis for generating purchase orders and managing supplier transactions through controls such as Purchase Order Approval, Purchase Order Accuracy, and Purchase Order Control. By formalizing purchase requests, organizations improve procurement transparency, maintain financial governance, and ensure spending decisions align with operational and financial objectives.
