What is automated, where AI helps, who signs off
Automation for the routine. A person on every decision that matters.
The reliable spine
The reliable spine is the deterministic three-way match: PO against goods-receipt against invoice, flagging every price drift, quantity and tax mismatch, duplicate payment and missed rebate, with clean invoices flowing through and only genuine exceptions reaching a person.
Where AI helps
AI is limited to reading the vendor invoice and rate contract into structured rows and matching a bill to the right PO and receipt; the match logic and the recovered figure stay deterministic.
Who signs off
A named person signs off anything touching money, stock, a customer promise, a regulated filing, a payment, a price, a credit decision or a people decision.
