Shops that receive a short briefing on quality control process convert noticeably better than shops that only receive stock.
Why quality control process matters on the Zen Air

In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen Air.
Functional testing of a sample from each batch is standard practice.

Commercial terms
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (115 units) | Tier 1 | 14-21 days |
| Pallet (1174 units) | Tier 2 | 30-45 days |
| Container (10542 units) | Tier 3 | 7-12 days |
