How the Approval Workflow Works
The process typically begins when an employee or authorized requester submits a purchase requisition containing details such as the requested item or service, quantity, estimated amount, supplier information, department, location, project, and business justification. The request is then evaluated against the organization's approval rules.
Depending on the configured workflow, a requisition may move through one or several approval levels. A lower-value request might require department approval, while a higher-value request could require additional finance or executive authorization. Approved requests can then proceed toward purchase order creation and subsequent purchasing activities.
- Request submission: The requester provides purchasing and accounting information.
- Rule evaluation: The workflow determines the appropriate approval path.
- Approval routing: The requisition is sent to authorized reviewers.
- Decision recording: Approvals, rejections, and comments create an auditable history.
- Purchasing execution: Approved requests can proceed into the appropriate purchasing process.
Core Components and Approval Controls
The effectiveness of a requisition workflow depends on clearly defined approval criteria. Organizations can align approval responsibility with spending authority, organizational structure, and financial accountability. Approval conditions may distinguish routine purchases from requests that require additional scrutiny because of their value, category, project, or department.
Segregation of duties is also important. The person requesting a purchase does not necessarily need to be the person approving it. Clear role definitions help establish accountability while making the approval path easier to understand and audit.
For organizations connecting requisitions with broader AP operations, AP Automation Software can support downstream invoice processing and payment planning while preserving approval controls. The requisition workflow therefore becomes one part of a broader source-to-pay process rather than an isolated approval step.
Connection With Invoice and Accounts Payable Processes
Purchase requisition approval can influence what happens after goods or services are ordered and invoiced. Once an approved purchase progresses into purchasing, subsequent invoices may need to be captured, validated, matched with purchasing records, coded, approved, and posted. In this context, invoice capture helps bring invoice information into the processing workflow, while invoice matching helps compare invoice details with relevant purchasing information.
For a broader view of the supplier invoice lifecycle, Vendor Invoice Processing 2025: AI Supplier Workflow Guide covers invoice capture, extraction, validation, matching, GL coding, approval, posting, and straight-through processing. invoice processing can therefore be viewed as a downstream activity that complements the purchasing authorization established by the requisition workflow.
Organizations can also use How Vendor Portals Improve Invoice Transparency to understand how supplier-facing visibility can support clearer communication around invoice status and processing milestones. These practices help connect purchasing authorization with subsequent financial operations.
Role in Financial Control and Cash Flow
Purchase requisition approval provides an opportunity to evaluate spending before an organization becomes committed to a purchase. Reviewing requests before purchasing helps management align expenditures with budgets, departmental priorities, projects, and established spending authority.
The workflow also supports better coordination between purchasing and payments. Once approved purchases eventually generate supplier invoices, payment activity can be managed according to the organization's authorization, cash position, due dates, and payment policies. This connection makes requisition approval relevant to both purchasing discipline and cash flow planning.
A related Payment Approval process generally governs authorization of the actual payment, which is distinct from approving the original purchase request. Keeping these stages conceptually separate helps organizations maintain clear financial controls from purchase initiation through settlement.
Relationship With Vendor and AP Approval Workflows
Purchase requisition approval should be distinguished from supplier onboarding and invoice approval. A Vendor Approval Workflow focuses on whether a supplier should be authorized for business use, while requisition approval focuses on whether a particular purchase should proceed.
After purchasing activity generates an invoice, an Accounts Payable Approval Workflow can govern the review and authorization of the payable. Together, these workflows can create a connected control framework covering supplier authorization, purchase authorization, invoice authorization, and payment authorization.
This structure also supports vendor management by clarifying responsibilities across procurement, finance, accounts payable, and business stakeholders. Each stage has a defined purpose while remaining connected to the organization's overall financial process.
Best Practices for Effective Requisition Approval
- Define approval thresholds: Align authorization levels with spending amounts and organizational responsibility.
- Use clear approval roles: Assign reviewers based on department, entity, project, or financial authority.
- Capture complete requisition data: Require sufficient information for purchasing, accounting, budgeting, and audit purposes.
- Maintain approval history: Preserve decisions, timestamps, comments, and routing information for accountability.
- Connect purchasing with AP: Maintain consistent information between approved requisitions, purchase orders, invoices, and payments.
- Review workflow performance: Monitor approval turnaround, outstanding requests, spending patterns, and exception volumes to improve financial operations.
