A supplier audit checklist turns impressions of a Zen Ultra factory into comparable data.
A range review that ignores supplier audit checklist will often produce a confident decision and a disappointing quarter on the Zen Ultra.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen Ultra.
Why supplier audit checklist matters on the Zen Ultra
Production capacity, quality records and certification should be verified on site.
Cash flow is the quiet constraint behind supplier audit checklist: the cheapest option is rarely the one that frees the most working capital.
Traceability of raw materials matters increasingly to downstream buyers.

- Retain one sealed sample carton from every batch for reference.

- Agree in advance who pays for return freight on a defect claim.
- Log sell through by account for the first eight weeks.
Commercial terms
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (133 units) | Tier 1 | 30-45 days |
| Pallet (1953 units) | Tier 2 | 21-30 days |
| Container (8564 units) | Tier 3 | 7-12 days |

Can several models be mixed in one shipment?
Yes, mixing models and flavours within a carton or pallet is common and usually helps first time buyers test demand.
Can packaging be adjusted for our market?
