What is Requisition Approval Hierarchy?
Definition
Requisition Approval Hierarchy is the structured chain of authority that defines who must review and approve purchase or spending requests at different levels within an organization. It establishes a clear sequence of decision-makers based on roles, financial limits, and organizational policies to ensure controlled and accountable spending.
How the Approval Hierarchy Works
The hierarchy determines the path a requisition follows from submission to final approval. It is typically embedded within a Purchase Requisition Workflow and aligned with predefined rules that reflect organizational structure and financial authority.
When a request is initiated, it moves through levels such as:
Department manager: Validates business need and budget availability
Finance team: Ensures alignment with Requisition Approval policies and financial controls
Senior leadership: Reviews high-value or strategic expenditures
Specialized approvers: Handles category-specific approvals like IT or legal
This layered approach supports a robust Approval Hierarchy that ensures every request is evaluated at the appropriate level.
Core Structure and Components
A well-designed hierarchy is built on clearly defined rules and responsibilities. It is often governed by a Procurement Approval Matrix that maps approval authority to spending thresholds and roles.
Approval levels: Multiple tiers enabled through a Multi-Level Approval Workflow
Threshold rules: Different approval requirements based on monetary value
Role-based routing: Assigns approvals based on job function rather than individuals
Delegation rules: Allows temporary reassignment of approval authority
Audit visibility: Supports tracking for reconciliation controls
Financial Control and Governance Impact
Requisition Approval Hierarchy is critical for maintaining financial discipline and preventing unauthorized spending. By ensuring that approvals are distributed across levels, organizations reduce the risk of errors and enforce accountability.
It directly contributes to:
Improved cash flow forecasting by validating commitments before spending occurs
Enhanced vendor management through consistent and timely approvals
Stronger alignment with budgeting and financial planning processes
Better coordination between procurement, finance, and operational teams
Practical Business Applications
Organizations implement requisition approval hierarchies across various procurement and finance activities to ensure consistent decision-making and control.
Operational purchasing: Routine expenses approved at departmental levels
Capital expenditure: Large investments requiring executive approvals
Inventory procurement: Managed through Inventory Approval Workflow for stock control
Service agreements: Integrated with Contract Approval Workflow for legal and compliance checks
Employee expenses: Connected to Expense Approval Workflow for reimbursements
Integration with Financial Workflows
The approval hierarchy does not operate in isolation; it is tightly integrated with broader financial processes. Once a requisition is approved, it often triggers downstream activities such as purchase orders, invoicing, and payments.
Key integrations include:
Alignment with Payment Approval Automation to ensure payments follow approved requests
Connection to Expense Approval Automation for unified expense governance
Linkage with Revenue Approval Workflow in organizations managing both procurement and revenue controls
Support for accurate financial reporting and budget tracking
Best Practices for Designing an Effective Hierarchy
To maximize efficiency and control, organizations should structure their approval hierarchies with clarity and flexibility.
Define clear authority levels: Avoid overlaps or gaps in approval responsibility
Align with organizational structure: Reflect reporting lines and financial ownership
Use threshold-based rules: Scale approvals with financial impact
Ensure transparency: Provide visibility into approval stages and status
Continuously refine: Update hierarchy as the organization grows or changes
Summary
Requisition Approval Hierarchy establishes a structured chain of authority for reviewing and approving purchase requests. By defining clear approval levels, aligning with financial policies, and integrating with key workflows, it enhances control, accountability, and operational efficiency while supporting strong financial performance.
