How to Set Minimum Order Quantity (MOQ) on Shopify

Quick answer: which method should you use?

For most stores, an app with checkout validation is the right choice. It’s the only method that truly blocks checkout when rules aren’t met, works on all plans, and requires no code.

What is minimum order quantity?

There are two types of minimums:

Minimum order quantity (MOQ) — the smallest number of items a customer must buy. Example: “You must order at least 12 t-shirts.”

Minimum order amount (MOV) — the smallest dollar value an order must reach. Example: “Your order must be at least $50.”

Both can be set per product, per collection, per variant, or for the entire cart.

Method 1: Using an MOQ app Recommended

This is the recommended approach for most Shopify merchants.

Step by step with Nex Minimum Order Amount MOQ

1. 1

   Install the app from the Shopify App Store.

2. 2

   Create a new rule — choose “Minimum Quantity” or “Minimum Amount.”



3. 3

   Set the scope — select specific products, variants, collections, or the whole cart.

4. 4

   Enter the minimum — quantity (e.g., 6) or amount (e.g., $50.00).



5. 5

   Set conditions (optional) — customer tag = “wholesale” for B2B, country = Canada for regional, or always apply for store-wide.

6. 6

   Customize the message — write what customers see. Example: “Minimum order is 6 units. Please add 2 more.”

7. 7

   Activate — cart warning + checkout validation are both active.

What happens when a customer doesn’t meet the MOQ

• —On the cart page: A clear message shows what they need to add.
• —At checkout: If they proceed without meeting the rule, the payment button is blocked with your custom message.
• —Customer action: They go back, add more items, and complete the order.

Why an app is recommended

1. Works on all Shopify plans (Basic and up)
2. No code required — set up in minutes
3. Checkout validation blocks payment (cannot be bypassed)
4. Cart page warning guides customers before they reach checkout
5. Supports conditions like customer tags, country, product, and collection

Method 2: Shopify B2B catalog rules Plus only

If your store uses Shopify’s built-in B2B features, you can set quantity rules directly in your catalogs.

How to set up

1. Go to Shopify Admin → Products → Catalogs
2. Click on the catalog you want to edit
3. Click Manage → Manage Products and Pricing
4. Hover over the product, click + Add in the Quantity rules column
5. Set the Minimum, Maximum, and Increment fields, then click Done → Save

Limitations

• Only works for B2B customers assigned to catalogs
• Does NOT work for regular D2C customers
• Rules apply per variant, not per product total (buying 5 blue + 5 red does not equal 10 of the product)
• Requires Shopify Plus or higher for full B2B features
• No custom error messages

When to use this method

Only if you have a dedicated B2B store using Shopify’s native B2B features and your MOQ needs are simple per-variant minimums.

Method 3: Custom Liquid code Cart only

You can add Liquid code to your cart template that checks quantities and shows a warning.

Basic example

Add this to your cart template (cart.liquid or cart-template.liquid):

{% assign min_quantity = 6 %}
{% assign total_quantity = 0 %}
{% for item in cart.items %}
{% assign total_quantity = total_quantity | plus: item.quantity %}
{% endfor %}

{% if total_quantity < min_quantity %}
<p class="cart-warning">
  Minimum order is {{ min_quantity }} items.
  You currently have {{ total_quantity }}.
  Please add {{ min_quantity | minus: total_quantity }} more.
</p>
{% endif %}

Serious limitations of the code approach

• Does NOT block checkout — it’s a visual warning only. Customers can still proceed to payment.
• Only works on the cart page — accelerated checkout, buy-now buttons, and direct checkout URLs bypass it completely.
• Theme-dependent — breaks when you update or change themes.
• Requires developer maintenance — any cart page change risks breaking the validation.
• No conditions — applies the same rule to everyone (no B2B vs retail differentiation).
• Per-product MOQ is very complex — requires significantly more code and is fragile.

When to use this method

Only as a temporary visual hint while you set up a proper solution. Not suitable as a standalone enforcement mechanism.

Choosing between quantity vs. amount minimums

You can combine both — require a minimum of 6 units AND a minimum of $50.

Tips for implementing MOQ successfully

Summary

The most important thing: checkout validation. A minimum order rule that can be bypassed isn’t really a rule — it’s a suggestion. Use a solution that blocks payment when the rule isn’t met.
