Air Bar Zen 4 Sample Order Workflow Checklist 2026

Published 2026 · VapeWholesaleHub trade desk

A disciplined sample workflow shortens the path from first interest to a Zen 4 purchase order.

Between the factory gate and the retail shelf, sample order workflow is where most of the value on the Zen 4 is either created or lost.

Consistency across batches matters more than peak performance for Zen 4, and sample order workflow is where inconsistency first appears.

Why sample order workflow matters on the Zen 4

Request samples with the final specification, not an approximation.

Where two suppliers look identical on price, sample order workflow is usually the variable that separates them over a full year.

Evaluate across at least two weeks of real use.

Practical notes for buyers

Cash flow is the quiet constraint behind sample order workflow: the cheapest option is rarely the one that frees the most working capital.

In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 4.

Checklist

Confirm the exact configuration in writing before the deposit is paid.
Retain one sealed sample carton from every batch for reference.
Review the reorder point after one full selling cycle.
Log sell through by account for the first eight weeks.
Record the arrival condition with photographs on the day of delivery.
Verify that artwork matches the approved compliance template.

Commercial terms

Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.

Volume commitments work best when they are structured as a rolling target rather than a single fixed number.

Volume tier	Indicative unit level	Lead time
Carton (162 units)	Tier 1	30-45 days
Pallet (827 units)	Tier 2	30-45 days
Container (6696 units)	Tier 3	14-21 days

All figures above are indicative working ranges used for planning. Final specification and commercial terms are confirmed in writing before any deposit.

Frequently asked questions

How many Zen 4 samples should we request?

Three to five units per shortlisted configuration is enough to judge consistency.

How quickly can a repeat order be produced?

For established configurations production typically runs two to four weeks, with transit on top depending on the chosen method.

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.

If only one thing changes after reading this, let it be the habit of checking sample order workflow before reordering.
