Cash flow is the quiet constraint behind inventory replenishment: the cheapest option is rarely the one that frees the most working capital.
Where two suppliers look identical on price, inventory replenishment is usually the variable that separates them over a full year.

Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.

| Pallet (1901 units) | Tier 2 | 7-12 days |
