Purchasing · Synthetic data · Deterministic calculation
Check invoice prices against dated contracts, identify possible duplicates and see which records still need a human decision.
Candidate amount to investigate
Constructed discrepancy candidates, not confirmed loss or savings. All findings are pending human review. Unknown amounts are excluded.
€35.00 + €120.00 = €155.00
Price deviations + possible duplicate = exclusive total
Excluded from the total: €20.00 of overlapping price alerts already covered by the possible duplicate.
16 invoices · 4 findings · 8 unknown cases · 2 matched · 2 excluded
The same discrepancy is counted once. INV-01 contributes its price difference; INV-02 contributes its remaining net amount as a possible duplicate. Matching records do not prove duplicate payment.
INV-02 · Pending review
€120.00 to investigate
INV-01 and INV-02 have the same normalized invoice number and matching business fields. €20.00 of price difference is excluded here to avoid double counting.
Confirm whether these records represent the same invoice; the retained ID does not establish legitimacy.
INV-01 · Pending review
€20.00 to investigate
€120.00 remaining − €100.00 under the applicable contract = €20.00 price difference.
Confirm the dated contract and credit allocation before accepting the finding.
INV-15 · Pending review
€10.00 to investigate
€110.00 remaining − €100.00 under the applicable contract = €10.00 price difference.
Confirm the dated contract and credit allocation before accepting the finding.
INV-05 · Pending review
€5.00 to investigate
€105.00 remaining − €100.00 under the applicable contract = €5.00 price difference.
Confirm the dated contract and credit allocation before accepting the finding.
Unknown cases keep their amounts unknown. Fully credited and cancelled invoices contribute zero.
| Invoice | Outcome | Reason | Candidate |
|---|---|---|---|
| INV-01 | candidate | price deviation | €20.00 |
| INV-02 | candidate | possible duplicate | €120.00 |
| INV-03 | matched | Within applicable contract | €0.00 |

| INV-05 | candidate | price deviation | €5.00 |
| INV-06 | excluded | Fully credited | €0.00 |

All 16 classifications and candidate amounts match independent fixture labels: 4 true findings, 0 false positives and 0 missed findings. This check applies to the constructed dataset and declared rules. Production accuracy, reviewer acceptance and time saved have not been measured.
Agent drafting unavailable. This example demonstrates deterministic checks. A validated agent-written investigation is still in development.
Structured single-line invoices, EUR net integer cents, explicit packaging conversions, invoice-date contracts and matching purchase orders. Ten boxes of ten units match one hundred individual units; INV-03 is not a price deviation. INV-04 uses the newly effective lower price.
Credits reduce remaining exposure under the declared allocation assumption. Fully credited INV-06 and cancelled INV-07 are excluded. Conflicting duplicate groups, absent contracts, unsupported currency or tax basis, missing purchase orders, fractional cents and excess quantity stay unresolved.
No live ERP connection, PDF extraction, invoice rejection, payment changes or supplier contact. Execution is disabled; all queue decisions are pending. Real accounting allocations and business rules require review.
A pilot would agree the accounting rules, compare approved reference data and measure how much investigation work remains after human review.
