Audit employee travel expenses with policy and receipt data
Prioritize explainable exceptions—duplicate claims, missing evidence, policy thresholds, currency issues, and unapproved merchants—for human review. Start with the what one row represents and definitions, calculate only from eligible records, and check the result against the source before using it.
Why the obvious method fails
Card feeds, claims, receipt images, travel bookings, approvals, and policy documents arrive separately. Similar amounts can be legitimate group expenses, while currency conversion and delayed posting create apparent duplicates.
What the file needs to answer
Prioritize explainable exceptions—duplicate claims, missing evidence, policy thresholds, currency issues, and unapproved merchants—for human review.
The assumption to make explicit
Two equal restaurant charges on the same trip may be a duplicate, split bill, deposit, or separate event; context is required before rejection.
A useful mental model
- Prioritize explainable exceptions—duplicate claims, missing evidence, policy thresholds, currency issues, and unapproved merchants—for human review.
- Claim totals must reconcile to reimbursement and card ledgers, every flag must state its rule, and cleared cases must remain available for false-positive monitoring.
- Two equal restaurant charges on the same trip may be a duplicate, split bill, deposit, or separate event; context is required before rejection.

Follow it with your own file
- Protect employee fields and match card transactions, claims, receipts, and trips without forcing uncertain matches.
- Attach the policy version effective on the transaction date and calculate transparent exception rules.
- Detect exact and near-duplicate claims, missing receipts, threshold breaches, and currency anomalies.
- Route cases to reviewers with source evidence and record cleared, corrected, and confirmed outcomes.
Check: Claim totals must reconcile to reimbursement and card ledgers, every flag must state its rule, and cleared cases must remain available for false-positive monitoring.
Three ways to approach the same file
| Approach | What it answers | What remains at risk |
|---|---|---|
| Quick spreadsheet total | A narrow descriptive question | Definitions, duplicate rows, timing, and exceptions may be hidden |
| Reviewed analysis | The stated decision with reconciled evidence | Human judgment is still required for policy and action |
| Ongoing monitored workflow | The same decision across new periods | unexpected column changes and changed business rules still need review |
Patterns that need context
- The source files do not share one documented what one row represents or cutoff.
- The decision owner cannot trace the headline result to eligible source records.
- Two equal restaurant charges on the same trip may be a duplicate, split bill, deposit, or separate event; context is required before rejection.
A method you can follow
- Define the decision: Protect employee fields and match card transactions, claims, receipts, and trips without forcing uncertain matches.
- Prepare the evidence: Attach the policy version effective on the transaction date and calculate transparent exception rules.
- Calculate the result: Detect exact and near-duplicate claims, missing receipts, threshold breaches, and currency anomalies.
- Review the exceptions: Route cases to reviewers with source evidence and record cleared, corrected, and confirmed outcomes.
