Generate SOX 404 sample selections, testing workpapers, and control assessments for internal controls audits.
What is sox-testing?
This skill assists with SOX compliance testing workflows by generating sample selections, creating testing workpapers, and documenting control assessments across key control areas (revenue, P2P, payroll, close, treasury, fixed assets, inventory, ITGC, entity-level, and journal entries). Use it when planning quarterly or annual SOX 404 testing, pulling samples for specific controls, building workpaper templates, or evaluating control deficiencies.
- Generate control matrices identifying key controls, their type, frequency, and relevant financial statement assertions
- Calculate and select transaction samples using random, systematic, or targeted selection methods based on control frequency and risk
- Create SOX control testing workpapers with test objectives, procedures, expected evidence, and results documentation
- Provide control deficiency assessments and classifications (effective, effective with exceptions, deficiency, significant deficiency, material weakness)
- Supply pre-built test step templates for common control areas including revenue recognition, procure-to-pay, financial close, and ITGC

sox-testing FAQ
The skill supports testing across nine primary control areas: revenue-recognition, procure-to-pay (P2P), payroll, financial-close, treasury, fixed-assets, inventory, ITGC (IT general controls), entity-level controls, and journal-entries. You can also specify any custom control ID or name.
Sample size is calculated based on control frequency (annual, quarterly, monthly, weekly, daily, or per-transaction) and adjusted for risk level, prior year deficiencies, and external auditor reliance. Higher-risk controls and those with prior issues require larger samples.
The skill supports three selection methods: random selection (default for transaction-level controls), systematic selection (for periodic controls at fixed intervals), and targeted selection (risk-based supplemental testing for high-dollar or unusual items).
No. The skill assists with SOX compliance workflows and documentation but does not provide audit or legal advice. All testing workpapers and assessments must be reviewed by qualified financial professionals before use in audit documentation.
The skill uses the CEAVOP framework: Completeness, Existence/Occurrence, Accuracy, Valuation, Obligations/Rights, and Presentation/Disclosure. Controls are mapped to relevant assertions to ensure comprehensive testing coverage.

Usage
/sox <control-area> <period>
Arguments
control-area— The control area to test:revenue-recognition— Revenue cycle controls (order-to-cash)procure-to-payorp2p— Procurement and AP controls (purchase-to-pay)payroll— Payroll processing and compensation controlsfinancial-close— Period-end close and reporting controlstreasury— Cash management and treasury controlsfixed-assets— Capital asset lifecycle controlsinventory— Inventory valuation and management controlsitgc— IT general controls (access, change management, operations)entity-level— Entity-level and monitoring controlsjournal-entries— Journal entry processing controls- Any specific control ID or name
period— The testing period (e.g.,2024-Q4,2024,2024-H2)
Workflow
1. Identify Controls to Test
Based on the control area, identify the key controls. Present the control matrix:
| Control # | Control Description | Type | Frequency | Key/Non-Key | Risk | Assertion |
|---|---|---|---|---|---|---|
| [ID] | [Description] | Manual/Automated/IT-Dependent | Daily/Weekly/Monthly/Quarterly/Annual | Key | High/Medium/Low | [CEAVOP] |
Control types:
- Automated: System-enforced controls with no manual intervention
- Manual: Controls performed by personnel with judgment
- IT-dependent manual: Manual controls that rely on system-generated data
Assertions (CEAVOP):
- Completeness — All transactions are recorded
- Existence/Occurrence — Transactions actually occurred
- Accuracy — Amounts are correctly recorded
- Valuation — Assets/liabilities are properly valued
- Obligations/Rights — Entity has rights to assets, obligations for liabilities
- Presentation/Disclosure — Properly classified and disclosed
2. Determine Sample Size
Calculate sample sizes based on control frequency and risk:
| Control Frequency | Population Size (approx.) | Recommended Sample |
|---|---|---|
| Annual | 1 | 1 (test the instance) |
| Quarterly | 4 | 2 |
| Monthly | 12 | 2-4 (based on risk) |
| Weekly | 52 | 5-15 (based on risk) |
| Daily | ~250 | 20-40 (based on risk) |
| Per-transaction | Varies | 25-60 (based on risk and volume) |
Adjust for:
- Risk level: Higher risk controls require larger samples
- Prior year results: Controls with prior deficiencies need larger samples
- Reliance: Controls relied upon by external auditors may need larger samples
3. Generate Sample Selection
Select samples from the population using the appropriate method:
Random selection (default for transaction-level controls):
- Generate random numbers to select specific items from the population
- Ensure coverage across the full period
Systematic selection (for periodic controls):
- Select items at fixed intervals with a random start point
- Ensure representation across all sub-periods
Targeted selection (supplement to random, for risk-based testing):
- Select items with specific risk characteristics (high dollar, unusual, period-end)
- Document rationale for targeted selections
Present the sample:
SAMPLE SELECTION
Control: [Control ID] — [Description]
Period: [Testing period]
Population: [Count] items, $[Total value]
Sample size: [N] items
Selection method: [Random/Systematic/Targeted]
| Sample # | Transaction Date | Reference/ID | Amount | Selection Basis |
|----------|-----------------|--------------|--------|-----------------|
| 1 | [Date] | [Ref] | $X,XXX | Random |
| 2 | [Date] | [Ref] | $X,XXX | Random |
| ... | ... | ... | ... | ... |
4. Create Testing Workpaper
Generate a testing template for each control:
SOX CONTROL TESTING WORKPAPER
==============================
Control #: [ID]
Control Description: [Full description of the control activity]
Control Owner: [Role/title — to be filled by tester]
Control Type: [Manual/Automated/IT-Dependent Manual]
Frequency: [How often the control operates]
Key Control: [Yes/No]
Relevant Assertion(s): [CEAVOP]
Testing Period: [Period]
TEST OBJECTIVE:
To determine whether [control description] operated effectively throughout the testing period.
TEST PROCEDURES:
1. [Step 1 — What to inspect, examine, or re-perform]
2. [Step 2 — What evidence to obtain]
3. [Step 3 — What to compare or verify]
4. [Step 4 — How to evaluate completeness of performance]
5. [Step 5 — How to assess timeliness of performance]
EXPECTED EVIDENCE:
- [Document type 1 — e.g., signed approval form]
- [Document type 2 — e.g., system screenshot showing review]
- [Document type 3 — e.g., reconciliation with preparer sign-off]
TEST RESULTS:
| Sample # | Ref | Procedure 1 | Procedure 2 | Procedure 3 | Result | Exception? | Notes |
|----------|-----|-------------|-------------|-------------|--------|------------|-------|
| 1 | | Pass/Fail | Pass/Fail | Pass/Fail | Pass/Fail | Y/N | |
| 2 | | Pass/Fail | Pass/Fail | Pass/Fail | Pass/Fail | Y/N | |
EXCEPTIONS NOTED:
| Sample # | Exception Description | Root Cause | Compensating Control | Impact |
|----------|----------------------|------------|---------------------|--------|
| | | | | |
CONCLUSION:
[ ] Effective — Control operated effectively with no exceptions
[ ] Effective with exceptions — Control operated effectively; exceptions are isolated
[ ] Deficiency — Control did not operate effectively
[ ] Significant Deficiency — Deficiency is more than inconsequential
[ ] Material Weakness — Reasonable possibility of material misstatement not prevented/detected

6. Document Control Assessment
Classify any identified deficiencies:
Deficiency: A control does not allow management or employees to prevent or detect misstatements on a timely basis. Consider:
- Likelihood of misstatement
- Magnitude of potential misstatement
- Whether compensating controls exist
Significant Deficiency: A deficiency (or combination) that is less severe than a material weakness but important enough to merit attention by those responsible for oversight.
Material Weakness: A deficiency (or combination) such that there is a reasonable possibility that a material misstatement will not be prevented or detected on a timely basis.
7. Output
Provide:
- Control matrix for the selected area
- Sample selections with methodology documentation
- Testing workpaper templates with pre-populated test steps
- Results documentation template
- Deficiency evaluation framework (if exceptions are identified)
- Suggested remediation actions for any noted deficiencies
