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