Air Bar Zen 4 Sample Order Workflow
Published 2026 · VapeWholesaleHub trade desk

A disciplined sample workflow shortens the path from first interest to a Zen 4 purchase order.
Distributors reviewing their Zen 4 range usually find that sample order workflow explains most of the variance in results between accounts.
Cash flow is the quiet constraint behind sample order workflow: the cheapest option is rarely the one that frees the most working capital.
Why sample order workflow matters on the Zen 4
Request samples with the final specification, not an approximation.
Freight consolidation changes the answer to sample order workflow at container scale, which is why small and large buyers reach different conclusions.
Evaluate across at least two weeks of real use.

Practical notes for buyers
Consistency across batches matters more than peak performance for Zen 4, and sample order workflow is where inconsistency first appears.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 4.
Checklist
- Retain one sealed sample carton from every batch for reference.
- Log sell through by account for the first eight weeks.
- Confirm the exact configuration in writing before the deposit is paid.
- Record the arrival condition with photographs on the day of delivery.
- Request batch photographs and a packing list prior to shipment.
- Check carton quantities against the commercial invoice line by line.
Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (68 units) | Tier 1 | 30-45 days |
| Pallet (551 units) | Tier 2 | 30-45 days |
| Container (17932 units) | Tier 3 | 7-12 days |
Frequently asked questions
How many Zen 4 samples should we request?
Three to five units per shortlisted configuration is enough to judge consistency.
Do you support long term supply agreements?
Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
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.
What happens if a batch fails inspection?
The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.
Final word
The buyers who do this well are not luckier; they are simply more consistent about the basics.
