Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Payment history is the single most reliable route to better terms, more than total annual volume.

|---|---|---|
| Carton (184 units) | Tier 1 | 21-30 days |
| Pallet (1644 units) | Tier 2 | 7-12 days |
| Container (11589 units) | Tier 3 | 14-21 days |
