Why quality control process matters on the Zen Pro
Incoming inspection sampling catches most issues before they reach shops.
The most common mistake is optimising for the first order instead of the fourth, which is where Zen Pro economics actually settle.
Functional testing of a sample from each batch is standard practice.

Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
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 (140 units) | Tier 1 | 21-30 days |
| Pallet (818 units) | Tier 2 | 21-30 days |
| Container (16211 units) | Tier 3 | 14-21 days |
