What Prime MOQ does
Prime MOQ enforces order limits on a Shopify store: minimum order quantity (MOQ), maximum quantity, case-pack multiples, minimum and maximum order value, weight limits, and repurchase limits that stop one customer buying too much over time.
Unlike a discount app, Prime MOQ does not change prices. It blocks checkout when a cart does not meet the conditions you set, and shows the shopper a clear message explaining why, on the product page and in the cart.
Every rule is enforced by a Shopify Function that runs at checkout, so a customer cannot get around it by editing the cart in the browser, using a direct checkout link, or disabling JavaScript. There is no setting that makes enforcement advisory.
Why merchants use it
Problem | The rule that solves it |
|---|---|
Selling below your margin on single-unit orders | Minimum quantity, or a minimum order value |
Resellers buying out limited stock | Maximum quantity, or a repurchase limit |
Products that only ship in cartons of 6, 12 or 24 | Case pack (sell in multiples of) |
Freight-sensitive goods on pallets or LTL | Weight-based order limit |
Wholesale accounts ordering under your minimum | Order value rule scoped to a customer tag |
The building blocks of a rule
Every rule is made of the same six pieces:
Conditions. The limit type (Quantity, Value or Weight) with its minimum, maximum and multiple values, plus an optional repurchase period.

Condition How to count. Whether each matching product is checked on its own, or all matching products are added together first.
Applied products (scope). Which products, collections, tags, vendors, product types, or the whole store the rule covers.

Scope Customer eligibility. All customers, or a specific tag, segment, customer list or purchase-history condition, optionally narrowed by country.

Customers Schedule. Start now or on a future date, with an optional end date.
Messages. The text a blocked shopper sees, per language.
How it differs from Discount Prime
Prime MOQ is built by the same team as Discount Prime, but the two apps solve opposite problems.
Discount Prime | Prime MOQ | |
|---|---|---|
What it does | Lowers the price when conditions are met | Blocks checkout when conditions are not met |
Storefront element | Discount badges, tiered price tables, BOGO widgets | One limit message on the product page and cart |
Typical use | "Buy 3, get 15% off" | "You must buy at least 6" |
The two apps are aware of each other and run side by side on the same store. A merchant with a case-pack rule in Prime MOQ can still run a Discount Prime volume discount on the same product.
