UC56: Expense Policy Violation Pattern Detection

The Problem

Individual expense audits catch line-item violations (alcohol on non-travel, meals above limit). But patterns reveal systemic issues: repeat offenders, split receipts to evade daily limits, weekend entertainment in non-travel roles, personal vendor patterns. These patterns require analysis across 12+ months and hundreds of employees. Manual pattern detection is impractical; violations persist undetected.

What the Agent Does

Ingests 12+ months of expense transaction history from SAP Concur / Expensify
Builds employee expense profile: role, department, expected travel frequency, historical spending patterns
Analyzes transaction patterns:
Repeat violator: same employee flagged multiple times for same violation type
Split receipt pattern: multiple receipts from same vendor on same day, amounts just below threshold
Weekend entertainment in non-travel role: entertainment charges on weekends for office-based employees
Personal vendor pattern: recurring charges from personal merchants (e.g., home improvement, personal services)
Peer comparison: employee spending significantly above peer group (same role, same region)
Generates pattern-based violation flags with supporting evidence and transaction references
Creates escalation list ranking employees by violation frequency and severity
Outputs pattern report for management action (coaching, policy reinforcement, disciplinary)

Data Requirements

Data Sources:

SAP Concur / Expensify , 12+ months of expense transaction history, receipt images/descriptions, employee IDs
Corporate card feeds (Visa, Amex) , Merchant names, categories, amounts, dates, employee assignments
Employee master , Role, department, business unit, employment status
T&E policy , Compliant hotel/airline vendors, per-diem limits, prohibited expense categories

Data Classification:

Public: None
Internal Structured: Expense transactions, employee roles, policy rules
Internal Unstructured: Receipt images, policy documents
External Third-Party: Corporate card feeds, merchant category data
Sensitive/Regulated: Employee spending data, behavioral patterns

Data Quality Requirements:

Timeliness: Monthly analysis (historical 12+ months refreshed monthly)
Completeness: 95%+ of expenses must have transaction records and merchant details
Accuracy: Merchant categorization and employee-role data must be current

Integration Complexity: Medium , Requires full 12-month expense history export from Concur/Expensify, employee data sync, and statistical pattern detection logic

Why It Scores Well

Pattern detection identifies systemic violators and policy gaps that point audits miss. Cost avoidance is material for large organizations (25 to 30% of repeat offenders). Behavioral deterrent is significant: employees aware of pattern detection are less likely to repeatedly violate. Strategic leverage is high because expense policy compliance is foundational to fraud prevention and cost control.

Regulatory Alignment

SOX 404: Internal controls over expense recording and authorization
FCPA/Anti-Corruption: Expense pattern analysis is a key anti-corruption control
Internal Policy: T&E policy enforcement across consistent application

Sprint Factory Fit

Sprint 1 (2 weeks)

Fits Sprint 1 because pattern detection requires statistical modeling and 12-month historical analysis. Discovery focuses on policy rule definition and sample violation pattern validation. Configuration focuses on pattern-detection thresholds, repeat-violation definitions, and reporting templates.
