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: the three-way match of purchase order, goods received and invoice, the rate-versus-agreed-rate arithmetic, the duplicate and short-load checks, the GST reconciliation and the rebate ledger all run on plain rules against the converter's own documents.
Where AI helps
AI is confined to reading resin and additive invoices, delivery challans and rate sheets that arrive as scans, PDFs and photos, extracting the figures and matching each line to the right purchase order and agreed rate; it proposes the flag, it never approves a payment or alters a number.
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.
