Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (149 units) | Tier 1 | 21-30 days |
| Pallet (503 units) | Tier 2 | 30-45 days |
| Container (11791 units) | Tier 3 | 14-21 days |
