# Invoice and purchase order checker — TradeCheck Team

Canonical: https://agiscorecard.com/workbench/tradecheck-team
Language: en
Method version: 2026-09-19.2

Compare invoice lines to purchase orders and flag duplicate invoice IDs.

## How this tool works

Invoice amount = quantity × unit_price. Match vendor + PO, then compare the amount within your tolerance. Duplicate checks use vendor + invoice.

## Input format

- Invoice lines: `vendor,invoice,po,quantity,unit_price,currency`
- Purchase order lines: `vendor,po,quantity,unit_price,currency`
- Previously recorded invoices (optional): `vendor,invoice`
- Allowed amount difference: `tolerance`

## Reproducible example

All prefilled business examples are fictional. Replace them with your own checked inputs.

```json
{
  "columns": [
    "Vendor",
    "Invoice",
    "PO",
    "Invoiced",
    "Expected",
    "Currency",
    "Review"
  ],
  "rows": [
    [
      "Sample vendor",
      "INV-1",
      "PO-1",
      "120.00",
      "100.00",
      "USD",
      "Amount mismatch"
    ]
  ]
}
```

## Limits and assumptions

Single-line PO / invoice comparison; split invoices and tax/freight need manual review. No OCR, ERP connection, payment approval or fraud guarantee.
