Air Bar Zen Plus: Quality Control Process for Distributors
Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Zen Plus order either protects or damages downstream relationships.
There is no shortcut on quality control process: the Zen Plus rewards preparation and punishes improvisation.
Where two suppliers look identical on price, quality control process is usually the variable that separates them over a full year.
Why quality control process matters on the Zen Plus
Incoming inspection sampling catches most issues before they reach shops.
Keeping a short internal note on quality control process for each SKU pays for itself the first time a dispute arises over the Zen Plus.
Functional testing of a sample from each batch is standard practice.
