Compare invoice draft rates vs standard rates and output CostGuard report
When & Why to Use This Skill
The CostGuard skill automates the auditing of financial billing by comparing invoice draft rates against established standard rates. It streamlines the reconciliation process by identifying discrepancies and generating a structured report with risk-based tiers (PASS, WARN, HIGH, CRITICAL), ensuring billing accuracy and effective cost management.
Use Cases
- Vendor Invoice Auditing: Automatically verify that service provider invoices align with pre-negotiated contract rates to prevent overpayment.
- Pre-payment Billing Verification: Review draft invoices before final processing to flag high-cost outliers or missing standard rate data.
- Financial Compliance & Reporting: Generate detailed CostGuard reports to document rate consistency and provide evidence for internal financial audits.
