Skills in this bundle
Expense & Travel Auditor
Audit travel & expense claims: invoice compliance, itinerary/contract consistency, duplicate detection, over-period stays, full audit report.
Voucher Auditor
Auto-generate ERP-compatible accounting vouchers from source documents (expense / purchase / sales).
Fraud Radar
Run a set of deterministic, explainable fraud heuristics over a bank statement. Two check types: fictitious_cash (round-number padding, large cash withdrawals, high-frequency identical amounts, weekend large amounts) and shareholder_misappropriation (related-party / shareholder keywords, outflow with no repayment / long-outstanding). Every hit lists the rule and evidence — leads for human review, not conclusions. Outputs a 2-sheet Excel.
Large-Amount Test
Audit-style large-transaction screening. Detects per-entry net amounts on both the bank statement and the journal, flags entries at or above a threshold, and cross-checks them so single-sided large amounts (the audit focus) stand out. Outputs a 4-sheet Excel: summary, large journal, large bank, one-sided large.
Working Hours Compliance
Deterministic working-hours compliance check. (Action Co-pilot: generates next-best-actions (actions.json), follow-up tasks and calendar reminders on top of the analysis — what to act on today.)

Real use cases
FAQ
Which claim and receipt formats are supported?
Expense claims, invoices, and travel detail (Excel/PDF), auto-structured and linked to receipts. All processing runs locally; data stays in your network.
Can the expense policy be customized?
Yes. Standards, limits, categories, and approval rules are configurable and checked line by line, with violations tagged by policy clause and reason.
What fraud signals can it detect?
Fabricated and sequential invoices, duplicate and split claims, anomalous time/place, and out-of-policy spend, with suspicious items alerted upfront and evidenced.
Why full coverage instead of sampling?
Automated auditing is not limited by headcount and checks every claim line by line, upgrading traditional sampling into full coverage and markedly reducing misses.
Is the audit report usable for audit?
Yes. It includes violation lists, recommended actions, and traceable voucher numbers meeting internal and external audit evidence requirements, exportable to PDF/Excel.
