Invoice processing & 3-way match. A production blueprint.
A 6-week invoice processing and 3-way match agent on Google's Gemini Enterprise Agent Platform. ADK, Memory Bank, Agent Registry, Model Armor.
The outcome.
- What it does
Three-way match without the BPO contract.
Reads the invoice, reconciles against PO and goods receipt, flags the exceptions, writes back to the ledger. Exception-only review by your AP team.
- Who it serves
AP, controllership, and the line-of-business buyer.
AP gets exception-only queues. Controllership gets the audit trail. The buyer gets a payment cycle that is no longer their problem.
- Business KPI
Touchless rate and exception turn-around.
Touchless processing on standard invoices target 75-85%. Exception turn-around drops by half on the cases that route to a human.

Persona. CFO, AP Director, Controller.
The CFO cares about working capital cycle time. Every day shaved off the invoice-to-payment loop is liquidity unlocked.
The AP Director cares about exception ratios. The blueprint eliminates the manual triage tier and routes the team to the cases that actually need a human.
The Controller cares about the audit binder. Every match decision is logged with the linked PO, GR, and invoice fields.
Timeline. 6 weeks.
The standard 6-week pilot methodology — discovery, build, govern, deploy.
