What Prime MOQ does
Most order limits on Shopify are cosmetic. A line of theme copy asks for a minimum of six, and the cart page shows a warning, but the constraint is not actually part of checkout. A drawer cart, a Buy Now button, or a draft order walks straight past it.
Prime MOQ puts the rule where it holds. Limits run through Shopify Functions, which means checkout itself refuses an order that breaks them. The three things you can bound are quantity, order value, and cart weight, and each can be scoped to a product, a variant, a collection, a tag, or the entire cart.
In practice that covers the rules merchants actually write: minimum six per order with a maximum of two per customer, wholesale orders that start at one hundred dollars, or a cart that has to weigh between ten and one hundred pounds.
What you can enforce
Minimum and maximum quantity
Floors and ceilings on how many units a cart may contain, per product or across the whole order.
Order value limits
Require a cart to clear a value before checkout, or cap how large a single order can get.
Weight limits
Minimum and maximum cart weight, for stores where a pallet or a courier limit sets the real boundary.
Rule scoping
Apply a rule per product, per variant, per collection, per tag, or across the entire cart.
Per-customer limits
Cap how much one customer can take, so a single order cannot clear the shelf.
Customer tags and countries
Narrow a rule to a customer segment or a market instead of applying it to everyone.
Enforced by Shopify Functions
The limit lives in checkout, so it holds even when the cart is reached by an unusual path.
Drawer carts, Buy Now, draft orders
The paths that usually slip past a themed message are covered too.
Unlimited rules
No cap on how many active rules a store can run, including on the free plan.
How a rule gets set up
Add the app block
Prime MOQ installs as a theme app block. There are no code snippets to paste into a template.
Write the rule
Choose quantity, value, or weight, then pick what it applies to: a product, a collection, a tag, or the whole cart.
Let checkout enforce it
The rule runs through Shopify Functions at checkout, so every cart follows it without further work.
Who tends to need it
Case-pack and wholesale sellers
Beverage and food suppliers, B2B retailers, and anyone selling in packs rather than singles.
Heavy and bulky goods
Tile, parts, and other catalogs where courier weight brackets decide what a valid order looks like.
Limited and collectible runs
Collectibles brands and small-batch makers who need a per-customer ceiling on a scarce product.
Stores with a minimum worth serving
Any merchant for whom an order below a certain size costs more to fulfil than it returns.
How it sits next to Discount Prime
Prime MOQ and Discount Prime are two separate apps with separate listings and separate installs. They solve different problems. Discount Prime decides what a customer pays. Prime MOQ decides what a customer is allowed to order in the first place.
They do share one thing: both read your Shopify customer tags. A wholesale segment you already use to drive wholesale pricing or volume discounts can carry its own order minimum without being rebuilt. Neither app requires the other.
Prime MOQ FAQ
What does Prime MOQ do?
It sets minimum and maximum limits on a Shopify order: quantity, order value, and cart weight. The rules are enforced by Shopify checkout itself through Shopify Functions, rather than shown as a message on the cart page that a shopper can route around.
Is Prime MOQ part of Discount Prime?
No. It is a separate Shopify app with its own listing and its own install. It comes from the same team, Aspedan, and the two apps read the same Shopify customer tags, so a segment you already use for pricing can also drive an order limit. You can install either one without the other.
How much does Prime MOQ cost?
There is a free plan with unlimited rules and all three limit types, quantity, value, and weight, with no credit card required. The site states that paid tiers, when they arrive, only add new capabilities.
Can I set a different limit for wholesale customers?
Yes. Rules can be scoped by customer tag and by country, so a wholesale segment can carry a different minimum from a retail one without running a separate store or catalog.
Does it work with drawer carts and Buy Now buttons?
Yes. Drawer carts, Buy Now buttons, and draft orders are covered, which are the paths that typically bypass a limit that only exists as theme copy.
Do I need to edit my theme code?
No. Prime MOQ ships as a theme app block, so there are no snippets to paste into a Liquid template.
