UC52: T&E Compliance Auditor

The Problem

Travel & Expense (T&E) audits traditionally sample 5 to 10% of expenses. Policy violations,personal charges, non-compliant hotel rates, alcohol above per-diem,escape detection. Computer vision on receipts can detect violations (alcohol logos, personal vendor patterns) that text OCR misses. 100% audit coverage using vision + policy rules eliminates undetected leakage and enforces compliance uniformly across the organization.

What the Agent Does

Ingests expense reports and receipt images from Concur / Expensify
Applies computer vision to extract receipt details: merchant, category, item descriptions, prices
Cross-references merchant category against policy rules (e.g., no alcohol on business travel, only approved hotel chains)
Detects policy violations: alcohol purchases, personal vendors, out-of-policy rates
Calculates daily meal & entertainment totals, flags exceed-limit days
Analyzes patterns across submitter: repeat violations, suspicious vendors, weekend entertainment charges in non-travel roles
Drafts audit comments and rejection notifications with violation details and policy citations
Generates monthly audit report ranking violators and policy-violation trends

Data Requirements

Data Sources:

SAP Concur / Expensify , Expense reports, receipt images (PDF, JPG), vendor names, amounts, dates
Corporate card feeds (Visa, Amex) , Transaction details, merchant category codes
T&E policy document , Compliant hotel rates, per-diem limits, approved vendors, prohibited categories
Employee master , Role, department, business unit (to identify non-travel roles)

Data Classification:

Public: None
Internal Structured: Expense transaction data, policy rules, employee roles
Internal Unstructured: Receipt images, policy documents
External Third-Party: Corporate card feeds, merchant category data
Sensitive/Regulated: Employee payment and reimbursement data

Data Quality Requirements:

Timeliness: Within 48 hours of expense submission
Completeness: 95%+ of expenses must have receipt image attached
Accuracy: Receipt image clarity target 90%+ for policy enforcement (readable merchant, amounts, item descriptions)

Integration Complexity: High , Requires computer vision API (e.g., AWS Textract, Google Vision) for receipt processing, APIs to Concur/Expensify for report ingestion, and policy rules configuration

Why It Scores Well

100% audit coverage replaces sampled 5 to 10%, catching more violations and deterring policy breaches. Computer vision detects alcohol and vendor patterns invisible to text OCR. Compliance uniformity eliminates subjective sampling bias. Pattern detection identifies systemic violators for management action.

Regulatory Alignment

SOX 404: Internal controls over transaction recording and authorization
FCPA/Anti-Corruption: Expense policy enforcement is a key anti-corruption control
Internal Policy: T&E policy compliance is foundational to expense management governance

Sprint Factory Fit

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

Fits Sprint 1 because receipt image processing and vendor pattern detection require tuning. Discovery focuses on policy rule extraction and sample receipt validation. Build sprint (2 weeks) focuses on computer vision fine-tuning, pattern detection rules, and audit report generation.

Comparable Implementations

AppZen: 100% audit coverage for Fortune 1000 , Computer vision on receipts, 99%+ accuracy
Concur Expense Audit , Policy violation detection and pattern analysis
