Expense report policy compliance and audit
Finance teams manually review expense reports against travel and entertainment policies, catching violations after the fact. AI can pre-screen submissions in real time, flag policy breaches before approval, and reduce the audit burden.
What this workflow is
The review of employee expense reports and corporate card transactions against the organization's travel, entertainment, and expense policies — checking for policy compliance, receipt validity, proper categorization, and approval thresholds before reimbursement.
Why teams struggle with it
Policy documents are long and complex, with rules varying by employee level, geography, and expense type. Reviewers process hundreds of reports per week and can't memorize every rule. Most violations are caught reactively during audits rather than proactively at submission, creating awkward clawback situations.
Why generic AI often fails here
Generic AI can read receipts but can't evaluate whether a $150 dinner is compliant without knowing the submitter's grade level, the number of attendees, the city's per-diem rate, and whether the attendees included external clients. Policy compliance requires cross-referencing multiple data points that generic tools don't have access to.
Where AI can actually help
Real-time policy checking at submission — flagging violations with specific policy references before the report reaches an approver. Receipt OCR with automatic categorization. Duplicate detection across card transactions and manual claims. Risk-based audit selection for post-payment review.
Inputs the system needs
- Expense policy document with rules by category, level, and geography
- Employee master data (grade, department, location, cost center)
- Expense report submissions with receipt images
- Corporate card transaction feeds
- Per-diem and mileage rates by location
- Historical expense data for pattern analysis
Outputs the system produces
- Pre-screened expense reports with compliance status
- Policy violation flags with specific rule references
- Duplicate expense detection alerts
- Categorization suggestions for miscoded expenses
- Risk score per report for audit prioritization
- Policy compliance dashboards and trend analysis
Controls that matter
- Policy rules must be maintainable by finance without IT involvement
- Flagged violations require human review — no auto-rejection
- Employee grade and entitlement data must stay current
- Receipt images must be retained for the defined retention period
- Appeals process must exist for disputed policy interpretations
When this is not a good fit
When expense policies are informal or unenforced, when receipt requirements are waived for most purchases, or when the organization has very few employees and manual review is fast enough.
