INVOICE PROCESSING
Draft a vendor dispute email for invoices that breach the rate card
When an invoice is flagged as over the negotiated rate, an agent assembles the contract evidence and drafts a professional dispute email back to the vendor.

What it does
This workflow turns a detected overcharge into a ready-to-send vendor dispute. Given a flagged invoice, an agent gathers the negotiated terms, calculates the exact overage, and writes a clear, polite email citing the agreed rate and the contract clause, attaching the math. It logs the dispute as a tracked case so nothing falls through.
When to use it
Use this when your team detects overcharges but loses recovery dollars because nobody writes the follow-up. It's for AP and procurement teams who want disputes drafted automatically with evidence, while keeping a human in the loop on the actual send.
How it works
- 1An incoming flagged-invoice signal arrives by webhook and triggers the run.
- 2The agent retrieves the vendor's negotiated rate card and the original invoice details.
- 3It computes the overage amount and the billing period affected.
- 4It drafts a dispute email referencing the agreed rate, the variance, and the relevant clause.
- 5The draft and a tracked case record are saved, and the email is staged in Gmail as a draft for a human to review and send.
