The ground Inventory needs:
- Products — the catalogue of what can be stocked, each with its unit of measure (Chapter 6). A product that does not track stock — a service, for instance — never appears here.
- Warehouses — the physical places stock lives: your shop, your store, your factory floor. Every quantity in this chapter belongs to a product in a warehouse; there is no stock floating nowhere.
- The neighbours who move stock — goods receipts bring it in (Chapter 4), waybills and issues take it out (Chapters 3 and 10), and this module's own adjustments, transfers and counts keep it honest in between.
Its switches (0.6) are the three tiers of 5.11: the base enquiries and reports are always on; Planning and Advanced are switched on when the business is ready for them, and everything in this chapter that depends on either is marked as it comes.
