UC53: SOX Testing Automation

The Problem

SOX 404 internal control over financial reporting requires documenting, assessing, and testing hundreds of key controls annually. Testing is labor-intensive: selecting random transaction samples, pulling support documentation, verifying compliance with control procedures, and documenting results. A single control test might require 4 to 8 hours of auditor time.

What the Agent Does

Ingests control matrix defining control ID, control narrative, key process steps, and test procedures
Automatically selects statistically significant transaction samples from ERP (e.g., 30 to 50 transactions per control)
Pulls transaction-level data and associated documentation (approvals, supporting evidence, GL posting)
Executes test procedures: checks approval authority, validates GL coding, confirms workflow sequence
Documents test execution: samples selected, test date, procedures executed, exceptions found
Generates exception summaries flagging failed controls or deviations from documented procedures
Assembles test working papers (samples, evidence, conclusions, sign-off) in Workiva or AuditBoard
Produces SOX readiness summary showing testing completion status and exception remediation tracking

Data Requirements

Data Sources:

Control documentation (Workiva, AuditBoard) , Control matrices, test procedures, control objectives
ERP (SAP, Oracle) , Transaction logs, approval sequences, GL postings, supporting documentation
GL detail , Account-level transaction history
Approvals systems , Authorization records, approval evidence

Data Classification:

Public: None
Internal Structured: Control matrices, test procedures, transaction samples, SOX documentation
Internal Unstructured: Control narratives, working papers
External Third-Party: None
Sensitive/Regulated: SOX test results, control exceptions (required for external auditor review)

Data Quality Requirements:

Timeliness: Within 2 weeks of control definition
Completeness: All key controls must have defined test procedures and sample populations
Accuracy: Transaction samples must be valid and representative; documentation must be retrievable

Integration Complexity: High , Requires APIs to pull controls from Workiva/AuditBoard, ERP transaction sampling logic, and working-paper document assembly

Why It Scores Well

Automation reduces SOX testing time by 60 to 70% (from 5 hours to 1.5 hours per control). Test objectivity is improved through systematic sampling and consistent execution. Working-paper quality and completeness are consistently high. External auditor confidence is strengthened through transparent, documented testing.

Regulatory Alignment

SOX 404: Requires documented and tested design effectiveness of key controls
PCAOB: External auditors rely on management's testing and documentation
COSO: Testing is integral to ongoing monitoring of control effectiveness

Sprint Factory Fit

Sprint 1 (2 weeks) + 1 build sprint (2 weeks)

Fits Sprint 1 because control procedure logic is complex and SOX-specific. Discovery focuses on control matrix extraction from Workiva/AuditBoard and test procedure documentation. Build sprint (2 weeks) focuses on transaction sampling logic, control testing rule engine, and working-paper assembly.

Comparable Implementations

Workiva AI Control Testing , Integrated SOX testing and documentation
AuditBoard Risk & Control Center , Control testing automation and working-paper management
