Separation of Duties

General Concepts
Separation of duties is an internal control principle that divides critical financial tasks among different individuals to prevent errors and fraud. In account reconciliation, it ensures that the person who prepares a reconciliation cannot also approve it, and that no single individual has unchecked control over a financial process from initiation to completion.
Why it matters
Separation of duties is a cornerstone of internal control frameworks including COSO and SOX compliance. The principle is simple: when a single person controls an entire process, there is no independent check on their work. Errors go undetected and fraudulent activity becomes possible because no one else is involved in the process to notice irregularities.
In the context of account reconciliation, separation of duties manifests primarily through the preparer-reviewer workflow. The preparer gathers data, performs the reconciliation, and documents the results. A different individual, the reviewer, examines the work and provides an independent assessment of its accuracy. Neither can perform the other's role on the same reconciliation, creating a mandatory checkpoint that catches mistakes and deters manipulation.
Beyond preparer and reviewer roles, separation of duties extends to other aspects of the close process. The person who records journal entries should not be the same person who approves them. The person who has access to modify account assignments should not also control the sign-off workflow. These separations create a web of independent checks that collectively reduce the risk of material misstatement, whether caused by honest error or intentional manipulation.
Auditors test separation of duties as a key control during financial audits. Deficiencies in separation of duties are frequently cited in internal control reports and can result in material weakness findings that affect investor and regulator confidence.
Modern financial platforms with built-in security controls enforce separation of duties through configurable role assignments and automated workflow routing.
How Arvexi handles this
Arvexi's Account Reconciliation platform enforces separation of duties through role-based access controls that are built into the workflow engine. The system prevents a user assigned as preparer from also acting as reviewer on the same reconciliation. Role assignments can be configured at the account, entity, or organizational level, with the platform automatically validating that no segregation conflicts exist.
The platform also supports the four-eyes principle for high-risk activities such as reconciliation template changes, materiality threshold adjustments, and auto-reconciliation rule modifications. Every role assignment and approval action is logged in an immutable audit trail that auditors can review to verify that separation of duties was maintained throughout the close period.
