Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (101 units) | Tier 1 | 14-21 days |
| Pallet (559 units) | Tier 2 | 30-45 days |
| Container (6931 units) | Tier 3 | 21-30 days |
