AI does the paperwork.
A person approves it.

AI drafts factory POs and inbound shipments, checks every settlement against your rate card, files reimbursement claims and answers questions about your data. Nothing posts or sends until someone on your team approves it.

Purchase order drafting

Turns a factory's confirmation into a PO, priced and checked against your restock plan and landed cost.
