The ground Procurement needs:
- Suppliers — created in this module (§4.6), with their terms, their currency, and — where you use landed cost — their default template (§4.10).
- Products and warehouses — receipts must have somewhere to land (Chapters 5 and 6), and purchase prices or costs to expect (Chapter 6).
- Company choices made once — your purchasing workflow depth (0.5); the landed cost and GRNI switches (0.6) — each off by default, each switching on a discipline this chapter explains.
Its neighbours: Inventory receives every receipt as stock — with lots and expiry dates where products are lot-tracked; Accounts receives the posted purchase invoice as a payable and the payment as bank money out; Sales shares the catalogue and the shelves. The Procurement cockpit (Chapter 2) reads it all back as spend, commitments and lead times.
