How to Source Air Bar Zen 4: Payment and Credit Terms
Published 2026 · VapeWholesaleHub trade desk
Payment and credit terms shape cash flow as much as unit price does for Zen 4.
The Zen 4 has settled into a stable position in the range, which makes payment and credit terms the natural next question for distributors.
Cash flow is the quiet constraint behind payment and credit terms: the cheapest option is rarely the one that frees the most working capital.
Why payment and credit terms matters on the Zen 4
Standard practice is a deposit with balance before shipment for new accounts.
The most common mistake is optimising for the first order instead of the fourth, which is where Zen 4 economics actually settle.
Established relationships may move to documentary credit or open terms.
