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 non-AI: a clean vendor and rate-contract master and a deterministic three-way match of order against goods-receipt against invoice that flags every price drift, quantity and tax mismatch, duplicate payment and missed rebate, so only genuine exceptions reach a person.
Where AI helps
AI helps read the invoice and the rate card and line them up for the match; the match itself stays deterministic and the payment decision stays with a person, because it must be defensible.
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.
