Invoice price-exception investigation
Run as the specialist sub-workflow after a three-way match fails, reconciling contracted, ordered, received, and invoiced prices.
What this workflow does
Run as the specialist sub-workflow after a three-way match fails, reconciling contracted, ordered, received, and invoiced prices. It uses deterministic matching where possible, isolates unresolved differences, and leaves every material classification to an accountable reviewer.
What you gain
Resolved discrepancy or vendor-owner task
What the AI agent changes
How this worked before
Exact matching worked for identical records; ambiguous names, missing fields, and inconsistent documents still created a manual queue.
What the AI agent changes
The agent combines deterministic checks with document understanding, explains uncertain matches, and sends only real exceptions for review.
Agent trigger
A three-way match fails specifically on price or quantity.
Inputs
- Process context: contract, PO, receipt, invoice, and tolerance rules
- Approved policies, ownership, and exception rules
Agent flow
- 1
Normalize records and validate period, currency, and ownership.
- 2
Apply deterministic matching rules before model-assisted classification.
- 3
Prepare a result covering a cited root cause and permitted resolution and isolate every unresolved difference.
- 4
Post only approved matches and retain the reconciliation evidence.
Human decisions
After step 3
The accountable process owner approves a cited root cause and permitted resolution.
Outcome
- Resolved discrepancy or vendor-owner task
- Evidence, exceptions, and audit trail
Guardrails
- Never auto-clear unresolved or material differences.
- Preserve source rows and match rationale in the audit trail.
Risks and mitigations
A plausible but incorrect match can hide a material difference.
Keep deterministic rules outside the model and require review above materiality thresholds.
Sources and evidence
Sources establish feasibility or impact. Not every metric comes from an identical implementation.
