Output Verification and Human-in-the-Loop Auditing

Output verification refers to the process of checking and validating AI-generated results to ensure they are accurate, consistent, and aligned with real-world expectations. This is essential because AI, especially large language models (LLMs) like GPT, can sometimes produce hallucinated or misleading outputs. 

Common Verification Techniques:

• Cross-referencing with trusted sources (e.g., tax codes, accounting standards)

• Rule-based validation (e.g., GAAP compliance checks)

• Numerical validation (e.g., totals, ratios, reconciliations)

• Logical consistency checks (e.g., balance sheets must balance)

Human-in-the-Loop auditing means a qualified human (e.g., an accountant or auditor) is involved in reviewing and approving the output generated by AI systems. Rather than trusting AI blindly, HITL ensures oversight, accountability, and regulatory compliance. 

Why HITL Is Important in Accounting:

• AI might misapply accounting principles

• Auditors and accountants bring context and judgment that AI lacks

• Ensures audit trail and professional responsibility remains intact

Use Cases in Accounting & Tax

• Automated Tax Filing: AI generates returns → Human reviews before filing

• Invoice Processing: AI extracts data → Human checks totals & vendor info

• Audit Trail Generation: AI flags discrepancies → Human investigates context

• Financial Reporting: AI drafts footnotes → Accountant verifies narrative compliance
