What you offer, and what you actually hold.
A catalogue item is what you rent or sell; stock is the physical units and quantities behind it. Serial-tracked units, bulk quantities, variants, kits and containers, with one availability figure across all of them.
- Serial-tracked units or counted bulk, chosen per item
- Kits built from components, with buildable quantity set by the scarcest
- Containers that stay packed between jobs and load as a single scan
