How Purchase Requisition Approval Works
The process begins when an employee submits a requisition containing the requested item or service, estimated cost, department, subsidiary, location, required date, and accounting information. NetSuite can route the request according to approval rules based on value, organizational hierarchy, purchasing category, or other configured conditions.
An approver can review the business justification, expected cost, budget impact, supplier information, and accounting treatment before approving the request.

Approval Rules and Control Design
Organizations typically configure approval thresholds that reflect spending authority. A $2,000 routine purchase might require departmental approval, while a $100,000 capital request could require finance leadership and executive review. Approval routing should mirror organizational responsibility rather than treating all requisitions identically.
- Amount thresholds: Higher-value requests can require additional approval levels.
- Department ownership: Requests can route to managers responsible for the associated cost center.
- Subsidiary rules: Multi-entity organizations can apply different authorization structures by legal entity.
- Purchase category: Capital purchases, services, inventory, and other categories can follow specialized review paths.
- Budget oversight: Approvers can evaluate whether expected spending aligns with available financial plans.
These controls create a clear distinction between requesting a purchase and authorizing the organization to proceed with it.
From Requisition Approval to Invoice Processing
Once a requisition is approved and converted into a purchase commitment, downstream records create the evidence required for invoice processing. Supplier invoices can later move through invoice capture, extraction, validation, GL coding, approval, and posting using the approved purchasing information established earlier.
Effective invoice matching compares supplier billing with purchase orders and receipt records so finance can confirm that quantities, prices, and delivered goods or services agree.

How Vendor Portals Improve Invoice Transparency also becomes useful when suppliers need visibility into invoice validation, approval, or posting status after an approved requisition has progressed through purchasing.
Connection With Accounts Payable Approval
Purchase requisition approval occurs before the organization commits to a purchase, while an Accounts Payable Approval Workflow applies later when supplier invoices and liabilities require financial review. These controls complement each other by authorizing both the original spending decision and the subsequent supplier obligation.
AP Automation Software can automate invoice processing and payment planning around approved procurement records, enabling finance teams to maintain accurate and controlled AP activity after the requisition stage. This creates continuity between purchasing approval, invoice validation, liability recognition, and settlement.
Payment and Period-End Impact
After invoices have been validated and approved, Payment Approval provides the final authorization point before supplier settlement. Approved payments can then be scheduled according to due dates, discounts, fraud controls, payment methods, and cash availability.
If goods or services have been received before the related invoice arrives, finance teams may also recognize accruals so expenses and liabilities are recorded in the correct accounting period. Approved requisitions and purchase orders can provide supporting evidence when assessing these period-end obligations.
Approval Metrics and Practical Example
A useful metric is Requisition Approval Rate = Approved Requisitions / Total Requisitions Reviewed × 100. If 920 of 1,000 reviewed requisitions are approved, the approval rate is 920 / 1,000 × 100 = 92%.
Approval cycle time is another important measure. If a requisition submitted on Monday is approved on Wednesday, the organization can evaluate whether that turnaround meets its purchasing expectations. Tracking approval time by department, value, or approver helps identify where routing rules can be refined for faster purchasing decisions while preserving authorization controls.
Best Practices for Requisition Approval
Organizations should require complete request information, maintain current approval hierarchies, define clear spending thresholds, and ensure accounting classifications are selected before approval. Requests should include enough context for approvers to understand the purpose, financial impact, and timing of the purchase.
Automation can route requests according to predefined conditions, send approval notifications, and maintain a consistent audit trail. Teams should review approval rules periodically as reporting structures, budgets, subsidiaries, or purchasing policies change so the approval framework continues to support operational efficiency and financial control.
Summary
NetSuite Purchase Requisition Approval controls spending before a purchase order or supplier commitment is created. By routing requests according to value, department, subsidiary, category, and authority levels, organizations can improve spend governance, budget visibility, procurement efficiency, and auditability. Strong requisition approval also creates reliable upstream data for invoice validation, accounts payable, payment planning, accrual accounting, and financial reporting.
