Trace the discrepancy.
Know what remains unproven.
Compare four independent data sources before writing a vendor claim. Handle outcome-based rules, contract periods, taxes and invoice adjustments. No account, key, network upload or payment required.
Source authenticity, contract validity, invoice completeness and actual recoverable money are not verified. This tool creates review candidates, never automatic refund claims.
Load four ledgers
Each file is processed locally. Download templates or run the synthetic example first.
Choose a sample or select all four CSV files.
Investigation results
Each exception links to the supplied scope and a recommended next step.
All findings are candidates. The source files and contract authenticity have not been independently verified. A zero net variance does not certify an invoice.
Keep a record of your review
Export a redacted summary for sharing. Raw source IDs never leave the browser unless you deliberately copy or export them separately.
Review-required vendor clarification
This draft is not a legal demand, invoice certification or refund entitlement. Review the actual agreement and invoice; no message is sent automatically.
What this audit can and cannot prove
Checks it can run
Duplicate records, source/meter discrepancies, supported contract rule counts, subtotal differences, declared taxes, credits, discounts and period alignment.
Checks requiring more evidence
Tiered or custom pricing, prorations, full tax determination, missing vendor outcomes, agreed contract versions, settlement, source completeness and recovery rights.
Recovery follows human review
Any request depends on contract, applicable law, jurisdiction, limitation periods and proof. This beta neither sends claims nor initiates payments or legal proceedings.
