Why merchants need this

The challenge and how Nex MOQ solves it

The Problem

Without order limits

Your 60% off flash sale is supposed to attract 100 new customers. Instead, 5 people buy your entire stock in the first minute. The promotion fails to reach its target audience.

This costs you revenue, customers, or compliance — every unprotected order is a risk

The Solution

With Nex MOQ

Set a per-product maximum during the sale period. Use AND conditions to combine Collection = "Flash Sale" AND Product tag = "on-sale" for targeted limits. Nex MOQ limits each customer to your chosen quantity (e.g., 3 per product), ensuring more customers get access to the deal.

Set the rule once — Nex MOQ enforces it at checkout automatically
