Approval Matrix
Approval Matrix - Clear Rules for Every Order
Control approvals by value, role, and cost center
An approval matrix defines which role or person may approve orders and purchase requisitions up to which value. It links value limits, cost centers, and hierarchy levels into transparent approval rules - for control, compliance, and audit-proof documentation.
Approval Matrix: Structured Approval Control
An approval matrix is a set of rules that defines which role or person may approve orders and purchase requisitions up to which value and in which cost center. It links value limits, responsibilities, and the four-eyes principle into clear, traceable approval rules for procurement.
How the Approval Matrix Works in Procurement
From value limit to audit-proof documentation
Value Limits & Responsibilities
The approval matrix assigns clear value limits to each role. A department approves small requirements, while larger order values move automatically to the next hierarchy level. This makes it clear at all times who is responsible for which amounts and categories - without manual coordination.
- Value limits per role
- Assignment to cost centers
- Category-based rules
Four-Eyes Principle & Control
Critical orders require approval by at least two people. The matrix enforces this four-eyes principle rule-based and prevents requirement and approval from resting in one hand. This reduces errors and misuse risks and creates the foundation for internal control systems.
- Two-person approval
- Separation of requirement and approval
- Rule-based checks
Escalation, Substitution & Compliance
If an approver is unavailable, stored substitution and escalation rules take effect so processes do not stall. Every approval is logged in an audit-proof manner. This keeps the entire approval path fully traceable and meets both internal and external compliance requirements.
- Substitution rules
- Automatic escalation
- Audit-proof logging
