Invoice exception review, with AI. A 30-day pilot you can measure.

Flag supplier, purchase-order and policy exceptions for finance review while payment approval and supplier decisions remain human-owned.

What the AI prepares

What the model drafts in a invoice exception review pilot, and where a person steps in.

  • Invoice checks

    Invoice lines are checked against thresholds, supplier records and purchase orders.

  • Duplicate and PO checks

    Missing PO, duplicate reference and unusual amount checks are grouped.

  • Supplier queries

    Supplier queries are drafted from approved wording.

  • Exception routing

    Exceptions are routed to finance, buyer or operations owner.

Errors, not intent, cause late payment

Admin errors, disputed invoices and lost invoices are the main reasons firms pay suppliers late. They are exactly what an exception check catches.

Common questions

Can the AI act on its own?

No. It prepares drafts and checks. A person signs off before any of this happens: approvals, payments or supplier commitments.

What does it cost to start?

The AI Rollout Diagnostic is £1,500 fixed and takes two weeks. You get a clear answer for this workflow: build, pause, clean up first or do nothing.

How do we know it worked?

Track exception volume, false positives, missed issues and reviewer changes. The pilot is kept only if those numbers improve.
