What Is a Purchase Requisition?

A purchase requisition is an internal document used by employees to request the purchase of goods or services. It kickstarts the procurement process by capturing key details like item descriptions, quantities, estimated costs, and reasons for the request - ensuring purchases are approved before any orders are made. 

Why Businesses Need Purchase Requisitions

Purchase requisitions serve as a critical first step in any well-structured procurement process. They not only organize how purchasing requests are made but also bring transparency, accountability, and predictability to company spending. Without them, businesses risk uncontrolled purchases, budget overruns, and misaligned procurement decisions. 

Here are the key reasons businesses rely on purchase requisitions: 

Prevents Unauthorized Purchases: Requisitions require internal approval before any order is placed. This stops employees from making ad hoc or unapproved purchases that could exceed budgets or violate policy. By adding a layer of oversight, businesses gain more control over what is bought - and why.

Increases Budget Visibility: Every requisition includes essential details like estimated cost, purpose, and urgency. This gives finance and procurement teams better foresight into upcoming expenses. With this information, leaders can adjust budgets, forecast more accurately, and avoid last-minute financial surprises. 

Streamlines Procurement Workflows: A standardized requisition process reduces confusion and delays, streamlining procurement workflows. Instead of chasing down approvals or vague requests, procurement teams get clear, documented needs. This accelerates vendor selection and order processing, saving valuable time and effort. 

Creates a Reliable Audit Trail: Requisitions document who requested the purchase, who approved it, and what the justification was. This paper trail is invaluable during audits, compliance reviews, and internal investigations - ensuring accountability at every step. 

Improves Internal Accountability: When employees must justify their requests, they tend to think more critically about what they really need. Requisition processes promote responsible spending behavior across departments and encourage a culture of fiscal discipline.

Supports Compliance and Policy Enforcement: Requisitions enforce company purchasing policies by aligning all requests with approved vendors, negotiated rates, and category-specific rules. This ensures every purchase is compliant with both internal and external guidelines. 

At its core, a purchase requisition is more than just a form - it’s a strategic control point that keeps procurement aligned with company goals. 

How Purchase Requisitions Improve Spend Control

Purchase requisitions help businesses gain control over spend before it happens. They act as an internal checkpoint that brings visibility, approval, and discipline to every purchase request - well before any money is spent. 

Here’s how purchase requisitions contribute to better spend control:

Improves Spend Forecasting: Requisitions help finance teams get visibility into planned purchases before they happen. Each request includes cost estimates and purpose, offering a clear view of future spend. Result: Teams can plan budgets more accurately, avoid last-minute spending spikes, and improve cash flow management. 

Reduces Maverick Spending: Employees can’t bypass the system with off-the-record purchases once requisitions are required. The process ensures all spend follows approved channels. Result: Businesses reduce unauthorized purchases, protect vendor relationships, and enforce compliance with internal policies. 

Eliminates Duplicate Purchases: With requisitions logged and centralized, it’s easier to track what’s already been requested. Duplicate or overlapping needs are flagged before approval. Result: Companies avoid buying the same product twice and reduce inventory waste

Ensures Policy Alignment: Requisitions route purchases through pre-set workflows that include procurement, finance, and compliance teams. Result: Each request is vetted for vendor contracts, category rules, and spending limits - ensuring consistency and accountability.

Supports Approval-Based Spend Discipline: Every purchase must pass through a defined approval chain. Whether it's a department head or finance, no spend happens without review. Result: Managers get a chance to assess necessity and priority, promoting mindful, policy-aligned spending. 

Provides a Digital Audit Trail: Each requisition is documented with timestamps, approvers, and justifications. This creates a full record of every step in the purchasing process. Result: Audits become smoother, disputes are easier to resolve, and compliance risks go down. 

Improves Vendor Negotiation Power: Early visibility into purchasing needs allows procurement to group similar requests or negotiate better rates with vendors. Result: Businesses can leverage volume discounts and avoid fragmented spend across vendors. 

Enables Real-Time Budget Checks: With digital requisitions, approvers can check current budget status while reviewing requests. Result: They can approve or reject based on available funds, keeping spending within control in real time. 

Together, these controls ensure that every dollar spent is intentional, approved, and aligned with business goals. Requisitions don’t just manage spend - they empower teams to manage it smarter.

Purchase Requisitions vs. Purchase Orders: What’s the Difference?

Purchase requisition process and purchase order process often get confused - but they serve very different purposes. Understanding the distinction is essential for setting up a clean, compliant procurement workflow that avoids delays, miscommunication, and budget errors.

Here’s a side-by-side comparison to clarify the key differences between the two:

Feature Purchase Requisition Purchase Order
Purpose Internal request to buy goods or services External document issued to a vendor to place an order
Who Creates It Employees or department heads Procurement or finance team
When It's Used At the start of the procurement process After requisition is approved and vendor is selected
Approval Required Yes, before any purchase is made No (already approved via requisition)
Sent to Vendors No, it stays within the organization Yes, shared with vendors as a formal order
Controls Spend? Yes, prevents unapproved spending Yes, finalizes terms and initiates purchase
Includes Item description, justification, estimated cost Item quantity, price, vendor info, payment and delivery terms

The Purchase Requisition Process: Step-by-Step Overview

The purchase requisition process standardizes how employees request goods or services. By following defined steps - from request to approval - it ensures purchases are justified, reviewed, and compliant before moving forward. 

To better understand what happens after a requisition is approved, check out our blog on Step-By-Step Guide to Purchase Order Process in 2024 to map the full procurement flow.

Here’s how a typical purchase requisition process flows in most organizations: 

1. Identify the Need: An employee or team recognizes the need for a product or service- like software, hardware, or supplies - and initiates a request to buy. 

2. Create a Purchase Requisition: The requester fills out a digital or paper form with details such as item name, quantity, estimated cost, and justification for the purchase. 

3. Submit for Approval: The completed requisition is routed to the appropriate authority - often a department head, finance team, or procurement manager - for review and approval. 

4. Review and Approve (or Reject): Approvers evaluate the request based on budget availability, business need, and vendor policies. They may approve, reject, or request more information. 

5. Forward to Procurement Team: Once approved, the requisition is sent to the procurement team to begin sourcing, vendor negotiation, and purchase order creation. 

6. Generate Purchase Order (PO): The procurement team creates a formal purchase order using details from the approved requisition and sends it to the selected vendor. 

7. Recordkeeping and Tracking: The approved requisition is stored in the procurement system for future audits, spend analysis, and tracking of the full purchase lifecycle. 

Common Challenges in Managing Purchase Requisitions

While purchase requisitions are key to spend control, managing them effectively can be tricky. Poor processes, lack of standardization, and delays often get in the way of a smooth procurement experience. 

Here are some common challenges in handling purchase: 

Lack of Process Standardization: Different departments often follow different steps or formats for raising requests, leading to confusion and delays. Solution: Implement a company-wide requisition workflow with standardized forms and approval hierarchies to streamline the process across teams. 

Slow Approvals and Bottlenecks: Waiting for approvals from busy department heads or finance leads can stall critical purchases. Solution: Use automated workflows with reminders and escalation paths to ensure approvals happen quickly without getting lost in inboxes. 

Insufficient Information in Requests: Incomplete requisitions lack cost estimates, item specs, or justification, forcing back-and-forth communication. Solution: Create mandatory fields in requisition forms and train employees on the key information needed to avoid rework. 

Poor Visibility into Request Status: Requesters and approvers often have no idea where a requisition stands - whether it’s stuck, approved, or rejected. Solution: Use a centralized procurement system that offers real-time tracking and status updates for every requisition. 

Duplicate or Unnecessary Requests: Without a centralized view, the same item might be requested multiple times or bought when already available. Solution: Integrate your requisition process with inventory or asset management tools to flag duplicates or already-available resources. 

Manual, Error-Prone Processes: Paper forms or spreadsheets can lead to data entry mistakes, missed approvals, and compliance risks. Solution: Switch to a digital purchase requisition tool that automates routing, stores records securely, and reduces human error. 

When businesses address these challenges with the right tools and processes, purchase requisitions shift from being a bottleneck to a strategic asset. The result? Faster approvals, cleaner records, and smarter spending across the board. 

How Automation Can Simplify Purchase Requisitions

Manual requisition workflows often feel like a game of broken telephone - emails get buried, approvals take forever, and important details fall through the cracks. These inefficiencies cost businesses more than just time - they lead to poor visibility, overspending, and frustrated teams.

Automation changes all of that. By digitizing and streamlining the entire requisition flow, businesses can speed up approvals, reduce errors, and gain real-time control over spend - without adding headcount. 

Here’s how the process looks before and after automation:

Before Automation After Automation
Approvals stuck in email threads Auto-routed to the right approvers with reminders
Manual forms lead to missing or incorrect data Smart forms with mandatory fields and data validation
No visibility into request status Live dashboards showing real-time request progress
Duplicate or unnecessary requests go unnoticed System detects overlaps and flags duplicates
Time-consuming PO creation Approved requisitions auto-generate purchase orders
Paper trails hard to audit Digital logs with timestamps, comments, and version history

Benefits of Using Purchase Requisitions Software

Using purchase requisition software takes the manual guesswork out of procurement. It brings structure, consistency, and transparency to the entire process - without slowing teams down. For finance and procurement leaders, it means better control. For employees, it means fewer bottlenecks. 

Here are the key benefits of using requisition software: 

‒ Standardizes the Requisition Process: Software ensures that every team follows the same steps - from request to approval. With built-in templates and guided forms, employees know exactly what’s needed, reducing friction and inconsistencies across departments. 

‒ Improves Approval Speed: Automated workflows route requisitions instantly to the right approvers. No more waiting on emails or chasing signatures. With reminders and escalation triggers, approvals happen faster and without manual follow-ups. 

‒ Reduces Errors and Omissions: Smart forms validate information as it’s entered. Required fields ensure nothing critical - like vendor name, cost estimate, or justification - is missed. This reduces rework and speeds up downstream processes like PO creation. 

‒ Boosts Visibility and Auditability: Digital systems track every action taken - who submitted, who approved, and when. All this data is stored in one place, making it easy to run reports, track trends, and respond quickly during audits. 

‒ Connects Seamlessly with Procurement Tools: Most requisition software integrates with procurement, inventory, and finance systems. That means fewer silos, smoother workflows, and end-to-end visibility into spending - from request to payment. 

‒ Supports Remote and Global Teams: With cloud-based tools, teams across different locations or time zones can raise, review, and approve requests from anywhere. This flexibility supports modern, distributed workplaces without compromising on control. 

Role of Purchase Requisitions in Compliance and Audit Readiness

Purchase requisitions create a clear paper trail that makes audits smoother and compliance easier. Every request is documented, approved, and traceable - helping businesses stay aligned with internal policies and external regulations. 

Here’s how requisitions strengthen audit and compliance readiness: 

Built-In Approval Trails: Every requisition includes details of who approved it, when, and why - creating a transparent audit log. 

Policy Enforcement by Design: Pre-set workflows ensure all purchases go through the correct budget owners, cost centers, and vendor checks. 

Consistent Documentation: Standardized forms reduce ambiguity and ensure complete, uniform data across all departments. 

Quick Access to Historical Records: Digital systems allow finance and legal teams to pull up past requisitions instantly - ideal for audits or dispute resolution. 

Helps Meet Regulatory Requirements: Requisitions help organizations comply with financial reporting standards, internal controls, and industry-specific regulations (like SOX or ISO).

Frequently Asked Questions on Purchase Requisitions

1. What are the benefits of using purchase requisitions?

Purchase requisitions bring structure to procurement by ensuring every request is reviewed before spending happens. They reduce rogue purchases, increase visibility into future expenses, and support better budgeting. They also help teams stay compliant with internal policies and create a reliable audit trail.  

2. How can purchase requisitions be automated?

Purchase requisitions can be automated using digital procurement tools. These systems allow employees to submit requests through smart forms, route them to approvers instantly, and integrate with inventory or finance systems. Automation reduces delays, prevents manual errors, and gives teams real-time insights into every request.

3. What is the difference between a purchase requisition and a purchase order?

A purchase requisition is an internal request to buy something - it needs approval before becoming an actual order. A purchase order is the formal document sent to a vendor after the requisition is approved. Requisitions control internal approvals, while POs authorize the transaction with external suppliers.  

4. Who is responsible for approving purchase requisitions?

Approval responsibility typically lies with department heads, budget owners, or procurement teams. The approval path can vary depending on the cost, category, or team making the request. In automated systems, this workflow is predefined to ensure speed, accountability, and policy compliance. 

5. How often should requisition processes be reviewed or updated?

Requisition workflows should be reviewed at least once or twice a year. Regular updates ensure that approval hierarchies, cost thresholds, and compliance requirements stay aligned with evolving business needs. Reviewing the process also helps uncover bottlenecks or opportunities for automation. 

6. What challenges can arise when managing requisitions manually?

Manual requisition processes are prone to missing information, delayed approvals, and poor tracking. Without automation, it’s hard to prevent duplicate requests or ensure policy compliance. This leads to overspending, audit risks, and an overall lack of transparency in procurement.
