Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (180 units) | Tier 1 | 7-12 days |
| Pallet (1344 units) | Tier 2 | 14-21 days |
| Container (18598 units) | Tier 3 | 30-45 days |
