Purchase Requisition vs Purchase Order: Processes, Roles, and Handoffs

Executive Summary

Finance leaders often ask: What’s the difference between a purchase requisition and a purchase order? The answer is critical for CFOs, Controllers, and Procurement Heads who want tighter spend control, faster cycle times, and error-free procurement.

This guide explores the purchase requisition process, how requisitions are converted into purchase orders, and the handoffs and roles involved. We’ll also show how Hyperbots’ Purchase Order Requisition Software automates this lifecycle with AI-powered Co-pilots that cut operating costs by up to 80%. By the end, you’ll understand how to streamline procurement and why Hyperbots is the most differentiated AI platform for purchase order automation today.

What Is a Purchase Requisition?

A purchase requisition (PR) is an internal request created by an employee or department when goods or services are needed. It is not a binding document with suppliers but an internal mechanism for initiating spend.

Core elements of a requisition include:

• Requestor name and department

• Item description and quantity

• Estimated cost or budget line

• Justification or business need

• Suggested vendor (if known)

The purchase requisition process ensures that finance teams validate spend before funds are committed.

👉 With Hyperbots Procurement Co-pilot, requisitions are auto-extracted, validated, and routed for approval with zero manual entry.

What Is a Purchase Order?

A purchase order (PO) is a formal, legally binding document sent from a buyer to a supplier. Once approved, it serves as the commercial contract for a transaction.

Key details in a PO include:

• Vendor information

• Itemized goods or services

• Quantities and pricing

• Delivery dates and terms

• Payment conditions

Unlike requisitions, purchase orders commit the organization to payment once the vendor fulfills the order.

👉 Hyperbots’ AI-driven automation ensures error-free PO creation, dispatch, and closure, integrating seamlessly into ERP systems.

Purchase Requisition vs Purchase Order - Core Differences

The Purchase Requisition Process

The requisition process acts as a gatekeeper for spend.

Steps in the purchase requisition process:

1. Request Initiation – Employee submits PR with details.

2. Validation – Budget and GL codes checked.

3. Approval Routing – Manager or finance approves/denies.

4. Conversion – Approved PR moves to procurement for PO creation.

👉 Hyperbots eliminates manual delays by enabling approval to PO creation in minutes, using AI-powered validation and anomaly detection.

Converting Requisition to PO

The transition from requisition to PO is the most critical handoff. Manual handoffs often cause delays, errors, and compliance risks.

Challenges in manual conversion:

• Missing fields or incorrect GL codes

• Duplicate or unauthorized requisitions

• Long approval cycles

With Hyperbots PR-PO Co-pilot, enterprises can:

• Auto-populate missing requisition fields

• Flag duplicates and anomalies instantly

• Seamlessly convert requisitions to PO with full audit trails

Roles and Responsibilities in PR to PO Workflow

Typical roles include:

• Employee/Requester: Raises requisition.

• Manager: Approves based on the budget.

• Procurement Team: Converts PR to PO, negotiates terms.

• Finance Team: Ensures GL coding, budget compliance.

• Vendor: Receives and fulfills the PO.

👉 With Vendor Management Co-pilot, clean vendor records ensure accuracy during PO dispatch.

Approval to PO Creation - Why It Breaks Down

Without automation, approval-to-PO creation is plagued by:

• Email bottlenecks are delaying manager responses

• Data entry errors when converting requisitions

• Compliance risks from unauthorized purchases

Hyperbots addresses this with:

• Automated PR validation

• Configurable approval workflows

• One-click PO generation once approvals are in place

Result: Faster approval to PO creation, error-free, and compliant.
