What it does

Runs a classic three-way match on every incoming supplier invoice. It compares the invoice line totals against the original purchase order and the recorded goods receipt held in Postgres, and only invoices that agree within your tolerance band reach the approval lane. Anything off-amount becomes a flagged exception with the deltas spelled out.

When to use it

Use it when you require PO and receipt verification before payment and your controllers are doing that reconciliation by hand. It enforces the control automatically and gives finance an audit trail of why each invoice passed or failed.

How it works

  1. 1A new invoice email in Outlook starts the run.
  2. 2The invoice's PO number, quantities, and amount are extracted.
  3. 3Postgres is queried for the matching PO header and the goods-receipt record.
  4. 4A branch checks whether invoice amount and quantity match PO and receipt within tolerance.
  5. 5On a match, a ClickUp approval task is created tagged Three-Way-Matched.
  6. 6On a mismatch, a ClickUp exception task is created listing the price and quantity deltas for a buyer to resolve.
