What Is a Purchase Requisition? A Beginner-Friendly Guide

A purchase requisition is an internal document used by employees to request the purchase of goods or services needed for their work. It is the first step in the procurement process, acting as a formal request that must be approved before any money is spent.

Think of it as a permission slip: an employee identifies a need (like new office chairs or software licenses), fills out a requisition form with details such as quantity, estimated cost, and reason, and then submits it to a manager or the purchasing department for approval. Once approved, the requisition is used to create a purchase order, which is sent to the supplier.

The main purpose of a purchase requisition is to ensure that all purchases are necessary, budgeted, and authorized. It helps prevent unauthorized spending, keeps track of expenses, and provides an audit trail for financial compliance.

For example, if a marketing team needs a new laptop for a designer, they would submit a purchase requisition specifying the model, price, and justification. After approval, the procurement team issues a purchase order to the vendor. Without a requisition, the purchase might happen without proper oversight, leading to budget overruns or duplicate orders.

Many beginners confuse purchase requisitions with purchase orders. While they are related, they serve different purposes.

• Purchase Requisition (PR): An internal request created by an employee to get approval to buy something. It does not constitute an order with a supplier.
• Purchase Order (PO): A legally binding document issued by the purchasing department to a supplier after the requisition is approved. It contains the final terms, quantities, prices, and delivery dates.

In simple terms: a requisition asks for permission, while a purchase order places the order. The requisition stays inside the company; the purchase order goes outside to the vendor.

For instance, if your department needs new printers, you fill out a requisition. After your manager approves it, the purchasing team creates a purchase order and sends it to the printer supplier. The supplier then ships the printers based on the PO.

Understanding this distinction is crucial for anyone involved in what is purchase requisition and the overall procurement cycle.

Implementing a purchase requisition process offers several key benefits:

• Cost Control: By requiring approval before purchase, companies can prevent unnecessary spending and stick to budgets.
• Audit Trail: Every requisition creates a record of who requested what, when, and why. This is invaluable for financial audits and expense tracking.
• Accountability: Employees think twice before requesting expensive items because they need to justify the need.
• Efficiency: Standardized forms and approval workflows reduce back-and-forth emails and speed up procurement.
• Vendor Management: With clear purchase data, companies can negotiate better deals with suppliers based on volume.

According to a study by the Institute for Supply Management, companies with formal requisition processes reduce procurement costs by up to 15% on average. This shows how a simple internal document can have a big impact on the bottom line.

For small businesses, even a basic requisition form can help avoid cash flow problems. For larger organizations, automated requisition systems integrate with accounting software to provide real-time budget visibility.

Understanding the steps in a typical purchase requisition workflow helps clarify what is purchase requisition in practice. Here's a simple breakdown:

1. Identify Need: An employee realizes they need a product or service (e.g., new software, office supplies, raw materials).
2. Complete Requisition Form: The employee fills out a requisition form with details: item description, quantity, estimated cost, department, budget code, and justification.
3. Submit for Approval: The form is sent to the appropriate approver(s) — usually a department manager or finance team — based on company policy and the amount requested.
4. Approval or Rejection: The approver reviews the request. If it aligns with the budget and business needs, they approve it. If not, they may reject or request modifications.
5. Create Purchase Order: Once approved, the purchasing department converts the requisition into a purchase order and sends it to the supplier.
6. Receive Goods/Services: The supplier delivers the items or performs the service. The receiving department checks the delivery against the PO.
7. Three-Way Matching: The invoice from the supplier is matched with the PO and the receiving report to ensure accuracy before payment.

This process might vary slightly depending on company size and industry, but the core steps remain the same. Automation tools like procurement software can streamline approvals and reduce manual errors.

A well-designed purchase requisition form captures all necessary details to make informed decisions. Here are the essential fields:

• Requester Information: Name, department, contact details.
• Date of Request
• Item Description: Detailed specification of what is needed (e.g., brand, model, size).
• Quantity and Unit of Measure
• Estimated Unit Cost and Total Cost
• Budget Code or Account Number (to verify funds)
• Justification: Why the purchase is necessary and how it benefits the business.
• Preferred Vendor (if any)
• Delivery Date Required
• Approval Signatures (or digital approval trail)

Including all this information upfront reduces the need for follow-up questions and speeds up the approval process. Many companies use standardized templates or software that auto-populates fields from a catalog.

Even with a clear process, mistakes happen. Here are common pitfalls and how to avoid them:

• Incomplete Forms: Missing details like budget codes or justification can delay approval. Always double-check the form before submitting.
• Ignoring Approval Limits: Some employees bypass the system by splitting a large purchase into smaller requisitions. This violates policy and can lead to disciplinary action.
• Poor Timing: Submitting requisitions at the last minute forces rushed approvals and may lead to errors. Plan ahead and submit early.
• Lack of Communication: Not informing the purchasing department about urgent needs can cause bottlenecks. Use notes or flags for priority requests.
• Not Using a Centralized System: Relying on emails or paper forms can lead to lost documents and confusion. A dedicated procurement system keeps everything organized.

By being aware of these mistakes, you can improve your own requisition workflow and help your team operate more efficiently.

To get the most out of your purchase requisition process, follow these best practices:

• Standardize the Form: Use a consistent template across the organization to reduce confusion.
• Set Clear Approval Hierarchies: Define who approves what based on dollar amount and department. For example, purchases under $500 can be approved by a manager, while over $5,000 require VP approval.
• Automate Where Possible: Implement procurement software that routes requisitions automatically, sends reminders, and integrates with accounting systems.
• Train Employees: Make sure everyone understands the process and why it matters. Provide simple guidelines and examples.
• Monitor and Improve: Regularly review requisition data to spot trends, such as frequent urgent requests or budget overruns, and adjust policies accordingly.
• Use Approval Tiers: For large purchases, require multiple approvals (e.g., manager + finance + executive) to ensure thorough review.

By adopting these practices, you can turn a simple document into a powerful tool for financial control and operational efficiency.

Now you know what is purchase requisition and why it's a cornerstone of smart procurement. From its role as an internal approval document to its impact on cost control and accountability, the purchase requisition helps businesses spend wisely and stay organized.

Whether you're just starting a new job or looking to improve your company's purchasing process, implementing a clear requisition workflow can save time, money, and headaches. Start by creating a simple form, define your approval steps, and consider using software to automate the process.
