Overview

Prepare invoice exceptions for AP staff by organizing the supporting evidence around duplicate invoices, missing purchase orders, amount mismatches or incomplete supplier details.

Why it works

The expensive part of an invoice exception is often the investigation, not the invoice itself. Preparing the evidence packet lets AP staff spend their time on decisions rather than searching.

How it makes money

One-off project

How to start

  1. Define the client's exception categories and approval thresholds.
  2. Collect a batch of invoices plus the relevant PO or supplier records.
  3. Normalize invoice numbers, supplier names and dates.
  4. Check for duplicate identifiers, missing references and amount mismatches.
  5. Use AI to prepare a short evidence summary for each exception.
  6. Keep every exception tied to its source documents.
  7. Route uncertain cases to the AP reviewer instead of deciding them automatically.
  8. Measure which exception types consume the most review time.
  9. Deliver a prioritized exception queue to AP.
  10. Report recurring causes such as missing POs or supplier-data errors.
  11. Use the pattern report to suggest upstream process fixes.
