The number DIANA is measured on

Every digital coworker is hired against one primary measure, agreed and baselined before build. The others are read alongside it so the primary cannot be moved at their expense.

Primary measure

Duplicate detection accuracy

  • Duplicate value prevented before payment
  • AP review time saved
  • Exceptions resolved within the agreed SLA
  1. 01

    Cash protected before it leaves, rather than recovered partially and slowly afterwards

  2. 02

    Every in-scope invoice screened, replacing sample-based assurance with population coverage

  3. 03

    AP review time redirected from searching for duplicates to adjudicating the ones that matter

  4. 04

    Control evidence generated as work happens, satisfying the duplicate-payment control test internal audit would otherwise sample annually

  5. 05

    Root causes routed upstream, since duplicate vendor records are the most common origin of duplicate invoices

What DIANA does alone, and what stays with your team

DIANA reports to the Financial Controller. Anything outside the written boundary goes to controls & investigations, payment approver or internal audit, with the evidence attached.

“Authorised. Logged. Reversible.”

DIANA in production at an Australian entertainment group

Duplicate checking ran through a legacy vendor-managed subscription that read a sample rather than the whole ledger. DIANA was trained on twelve months of the group's own accounts payable history in SAP.
