Audit Evidence Extraction & Assessment Framework
Extract & assess audit evidence against assertions using ISA/PCAOB-aligned matrices
What You Can Do
You can rapidly process client documents—financial statements, contracts, bank confirmations, board minutes, and control narratives—to extract relevant evidence and classify it by audit assertions (existence, completeness, accuracy, valuation, rights/obligations, presentation). The skill evaluates evidence quality using ISA/PCAOB criteria, flags gaps in coverage, and generates structured assessment matrices that strengthen your audit file defensibility and reduce rework during review.
Features
Automatically categorize evidence by audit assertion type to ensure comprehensive coverage across all audit objectives
Aggregate and cross-reference evidence from contracts, confirmations, minutes, and internal control documentation into unified matrices
Rate relevance, reliability, and sufficiency of each evidence item using ISA/PCAOB standards to prioritize testing efforts
Flag missing or weak evidence before fieldwork completion to reduce rework and strengthen conclusions
Extract and evaluate internal control evidence to document design gaps and operating effectiveness support
Generate matrices and working papers formatted for inspection-ready audit documentation
Extract and assess evidence from multiple pages or documents simultaneously while maintaining classification accuracy
Tailor evidence classification to specific audit areas (revenue, receivables, inventory, fixed assets, debt, equity)
Example Output
Example 1: Revenue Assertion Evidence Matrix
| Evidence Source | Assertion | Relevance | Reliability | Assessment | Gap? |
|---|---|---|---|---|---|
| Sales contracts (Client file) | Existence, Rights/Obligations | High | High | 12 major contracts reviewed; all signed by authorized parties | No |
| Revenue cutoff testing (Bank deposits Dec 28-31) | Completeness, Accuracy | High | High | 3 transactions identified; all properly recorded in Dec | No |
| Receivables aging (as of 12/31) | Valuation | Medium | Medium | 2 accounts >90 days; allowance analysis pending | Follow-up |
Example 2: Control Design Gap Summary
Based on revenue cycle process narratives:
- ✓ Pricing authority documented and tested
- ✓ Segregation of duties (order entry/cash receipt) observed
- ⚠ Credit approval for customers >$500K not formally documented
- ⚠ Monthly reconciliation of sales journal to GL delayed 15+ days
Example 3: Evidence Sufficiency Alert
Inventory assertion status:
- Existence: 3/3 evidence items collected (adequate)
- Completeness: 1/3 evidence items collected (GAP: need cutoff testing, perpetual vs. physical reconciliation)
- Valuation: 0/2 evidence items collected (GAP: need cost basis support, obsolescence analysis)
What's Included
- SKILL.md instruction file with assertion framework and quality scoring criteria:
- Evidence Classification Matrix template (Excel/CSV-ready format for 6 audit assertions):
- ISA/PCAOB Evidence Quality Checklist (relevance, reliability, sufficiency scoring guide):
- Multi-area Evidence Summary template (revenue, receivables, inventory, fixed assets, debt, equity):
- Control Design Gap Assessment worksheet (documents design weaknesses and testing requirements):
Who It's For
- External auditors — Systematically extract and organize evidence during planning and fieldwork phases
- Audit managers/partners — Review evidence adequacy and file defensibility before fieldwork sign-off
- In-charge auditors — Consolidate evidence from team members and identify gaps early
- Public company auditors — Build PCAOB-compliant audit files with assertion-aligned documentation
- Audit committee coordinators — Prepare evidence summaries for inspection-ready audit documentation
Best For
- Evidence extraction from multi-page client documents during planning and fieldwork
- Assertion-based audit file organization and gap analysis
- Control design and operating effectiveness assessment documentation
- Multi-area evidence consolidation (revenue, payroll, purchases, cash, investments)
- Audit inspection preparation and defensibility review
