# Approver

## Overview

The Approver reviews and authorizes documents submitted by other actors. For purchase orders, they control the transition from SUBMITTED to ORDERED, ensuring procurement spend is authorized before supplier commitment. The same user may hold both originator and Approver roles — separation of duties is not enforced at the application level. The Approver does not participate in the Transfer Order flow yet — the approval module integration for Transfer Orders is intentionally deferred and will reintroduce a SUBMITTED → CONFIRMED path at that point.
